REVIEW: Purity Audio K.I.C.A.S. Caliente home headphone amp - updated with comments on regular KICAS - Page 10

post #136 of 379
I have a Caliente too but I'm using my HD650s with them and the match is great. I haven't done much listening with my DT770/80 Pros and my Caliente since I got the HD650s but I remember the sound being unimpressive. The warmth and detail that the Caliente offers is masked by the DT770s in my experience.
post #137 of 379
Thanks for the heads up, alwayshungry. Do you know how the bass compares between the DT770s and the HD650s with the KICAS Caliente?
Sounds like I'll have to try another set of headphones. Hmmm..

Tbonner1 mentioned the KICAS Caliente with Denon AH-D5000s. Can anyone else comment on them (or the D2000s) together?

I have the regular KICAS and I have to say that it is a great match for the D5000s (never heard the 2000s). I went with the regular version due to the phones I wanted to use with it (D5000, Pro900) and since they are laid back and warm already, the regular version gives them a nice sparkle.

Oriel was great in helping me out with the decision and his customer service is excellent.

BTW, all the phones I throw at the KICAS sound great, whether 300ohm or 25-32ohm.
Great versatile amp....

Hey booz I just spent some time going back to my DT770s with some music that I'm pretty familiar with (Jazz, alternative, rock, etc) and I think you should try another pair of cans before you give up on the Caliente. The DT770s don't sound bad persay but in comparison to the 650s I noticed the following:
(1) Noticeable loss of details across all frequency ranges. This is especially prevalent in the mids but also gives the bass the perception of "muddiness". There is lack of separation in the highs as well.
(2) Boomy bass as I mentioned. Lack of clarity and boomy bass.
(3) Some harsh highs - although most high frequencies are recessed in the DT770, some are not smooth and have a harshness to them. This is very noticeable compared to the HD650 which sound very smooth but detailed at the same time.
Overall the HD650s have a very smooth warm sound with Caliente and the detail is amazing. I have found it to be a very musical complement between the 2. In comparison, the DT770s it almost sounds like you are listening to the music through a cardboard box and really don't take advantage of the strengths of the Caliente. Keep in mind though that I have not compared the Caliente to other high end amps but I have had my 650/caliente combo for about a month but listen about 30-40 hours a week. I hope that helps.

EDIT:
I also forgot to mention soundstage but thats where the cardboard box analogy comes in. I just switched back to my HD650s and they give a real feeling of space and whereas the DT770s just feel like everything is directed straight at your head.

I will try to repeat my deleted post - if you are comparing the XM4 with bass boost ON to the KICAS you are not comparing apples to apples. Really, if you feel you need bass boost, you would be best to stick with amps that have that feature.

And differences between amps can be subtle, but for me very meaningful over the long haul.
post #142 of 379
Thank you for the comparison, alwayshungry. I get the feeling that this amp has a lot of potential, so I'll definitely pick up a pair of HD650s next.
Ya know, the more I listen to the KICAS, the more I realize that everything is significantly better than the XM4, and I anticipate to notice it even more as I continue to listen to it. I guess my expectations different from my first impressions, but as Skylab said, it takes time to truly appreciate the differences

boozcool, please allow me to pick up on your "feeling that this amp has a lot of potential", because I am still finding out just how much potential by hearing it become actual as I make improvements to the rig that it is in. I've been loving the way the Caliente has been driving my HD650s since July when I first bought it from Purity Audio. Recently, I replaced the Equinox HD650 cable that I've had since February with an ALO 18 AWG Jena Labs Cryo Wire Sennheiser cable. With the Caliente driving these newly-cabled phones, it showed me even more of what has always been coming from the source through the Caliente, but was being limited on the way to the phones by the headphone cable. I could run through the gamut of the categories on the audiophile scorecard, but the improvement of all such aspects of audio performance through and from the Caliente with this rig change has been a jaw-dropper to me. It's been one of those times when I've been going through listening sessions to hear all of my music collection again, so familiar and yet a fresh experience of new discovery all at once. I thought that I'd been actualizing the potential of the Caliente, but I have been hearing of late just how much more it is capable of after widening an audio bottleneck that had been there from this amp to my phones. There's a lot of potential in the Caliente which becomes actual as investments are made in the rest of the audio path. This makes it a very good and cost-effective choice of an amp around which to grow an ever-improving end-to-end headphone audio rig. It would take a lot to get to where the Caliente were to become the bottleneck.

sbulack, i see you have the HD600 with cardas. have you tried this combination with the kicas? would love to hear your thoughts and impressions.
post #145 of 379
I definitely agree with you, sbulack. The Caliente seems like its being held back a bit. Any recommendations for a DT770/80 recabling? (Preferably under $200)

I have never had the opportunity to listen to the DT770/80. I can offer some observations about improvements worth-the-cost from recabling three different sets of phones which may help you to figure out how to widen this bottleneck in your own rig. Two of these observations are my own, the third comes from posts from markl. I have used his observations successfully multiple times to make successful rig changes.

Some recablings seem to be targetted for specific phones. The Cardas Sennheiser replacement cable, for instance, seems to get its best reviews when used on the HD600. For the HD650, the Equinox or APS, from my reading, get more good impressions posted about them than the Cardas. I own both the Cardas and the Equinox replacement cables. I prefer the Cardas on my HD600 and the Equinox on my HD650. The best sound from my HD650, to my ears in my Caliente rig, has come from the ALO 18 AWG Jena Labs Cryo Wire replacement cable. I have not yet tried the Jena wire cable on the HD600's, but I will, in order to assess whether or not I hear the Jena cable to bring out more from the HD600 than the Cardas cable tailored to them. The Cardas cable was about $150, and when I installed it on the HD600, the differences that I heard were sufficient in kinds and degrees to make it well worth its price in my listening to music.

I've been a long-time big enjoyer of a pair of Grado SR225 phones (from late 2003 to the present). Last December I purchased a pair of the ALO-modded SR225 (hardwood cups), cabled with 18 AWG Jena Labs Cryo Wire. On the one hand, its the familiar (and much enjoyed) sound of the SR225 - but taken to a whole new level of spatial, dynamic range and timbral competence. It was the real success of this recabling that was a factor for me to decide (about 10-11 months later) to make the purchase of the ALO Jena Cryo Wire Senn replacement cable - which has turned out to be a very successful improvement to those phones.

Markl has developed a set of improvements for the Denon 5000's and 2000's, and his own assessment of the recabling of those which brings out their best is 22 AWG Jena Labs Cryo Wire. One of the recablings with which he compared the Jena Wire recabling was the well-regarded APS recabling.

Also involved in my decision to spring for the ($385) ALO Jena Labs Cryo Wire Senn cable for the HD650 was this finding by markl that this wire was the best he'd heard on the Denon phones. Prior to this finding by markl, I was wondering if the Jena wire, which had worked wonderfully well on the SR225, were also well-suited to the HD650. Markl's discovery that it also worked really well on the Denons got me thinking that it might just let more audio signal and power through and be a generally good recable wire, rather than being targetted to bring out more of this or that particular aspect of audio for a particular phone.

Will the Jena Cryo Wire bring out the best from the DT770/80? Looking at the results above on a set of three different phones that the folks who've heard them have characterized as being rather different, there is some basis on which to think that it could. I surely can't say from any experience. In fact, I haven't even listened using a pair of DT770/80, ever.

I am aware that what I am about to say next has recently received some criticism, but there is also the factor of how your hearing and sonic goals matches that of markl and me. I know from the items of gear that markl has discussed, and that I have also heard, that my observations and assessments agree well with his. Before anyone else could accept our observations and assessments as a basis for making a purchase decision involving enough money to buy another very decent amp or set of phones, they'd have to first assess how well our observations and assessments agree with theirs.

I hope that these observations, assessments and thoughts have been helpful enough to make it worth the threadjack away from the Caliente for a monent to have posted them.

I had originally posted about the Senn recabling NOT to veer the thread off onto a phone recabling sidetrack, but to highlight the untapped potential of the Caliente (detected by boozcool) which was able to show itself in actual performance in my rig with this improvement to the audio path downstream from it. I'll end there, to do my part to help get the thread back on track.

Soon, I will post my observations and assessments of the performance of the Caliente with the HD600 with both Cardas (as requested by chouman) and ALO Jena Cryo cables, with a focus on the performance of the Caliente to drive those phones.

The Jena wire is especially good with dark sounding cans. The HD650 benefits a lot from it. The DT770 may improves too.
post #148 of 379
Hello!

Sbulack, are you still as excited about your amp as you were a month ago?

I'm certainly interested in this amp. I have a pair of AD2000's that need good, warm/dynamic/punchy amplification, which would also power up the bass a bit.. They are low impedance/efficient phones though.
Is it true that you cannot hear noticeable hiss from your Shure 530's plugged into the amp?!?
I'm sorry, but this is dazzling
Also, the gain seems to be relatively high, from what i've read/been told. Is this a problem with low impedance/sensitive phones? Can you use it further than 9.00 o'clock, while not blowing your brains out? Of course the source has something to do with this too.. But just out of curiosity.

Thanks

-K

1) I'm actually more excited about it now than before. Up till now, I've only owned the Caliente in the warmer months of the year (Summer, Fall). Now that the temperatures are dropping and I'm moving into my late-Fall/Winter listening preferences (which are more subtle and refined) I was wondering how the Caliente would do. It's doing great. It delivers clean, clear, fully formed subtleties against a clean, quiet background. It's a really good all-arounder amp, and now for all seasons as well.
2) No doubt that the Caliente delivers on the warm - but it's not a warmth that steps on the rest of the acoustic spectrum. It's sufficiently tight and transparent that it supplies its satisfying effect without detracting from the other effects in the music going on at the same time.
3) Here's a link to what I posted about the performance of the Caliente with the Shure SE530:
REVIEW: Purity Audio K.I.C.A.S. Caliente home headphone amp - updated with comments on regular KICAS - Page 13 - Head-Fi: Covering Headphones, Earphones and Portable Audio
It IS true (in the sense that I DID actually hear) what I posted about the performance of the Caliente and the most sensitive phones I own, the Shure SE530. What I posted is how I hear it - my hearing has undergone general testing multiple times in my adult life and I have never been diagnosed with any hearing deficiency, and neither do I think that my ears are especially sensitive.
4, 5 & 6) Neither the gain of the amp nor the performance of the pot at any placement has ever become an issue in my use of the Caliente. Because of this, I don't have a mental catalog of "O'Clocks" that I use. I simply adjust the pot clockwise or counterclockwise (mostly without looking at it) until what I hear is at the desired level and sink into the enfolding embrace of the music. This is true with every phone I've used with it: Shure SE530, Grado SR225 (stock and ALO Modded), Beyerdynamic 531 & 831, Sennheiser HD600(cardas)/650(Equinox,SLO). For sources, I've used the lineout of a 5.5G iMod, a portable DAC (the Picollo by AOS), a now discontinued iRiver 350 PCDP, and a SONY pocket AM/FM-stereo radio. With every source/phone combination that I've used with the Caliente, setting the desired listening level with the pot has been a matter of issue-free "set it and forget it" (with thanks to Ron Popeil). Have I always set the Pot at-or-beyond 9 O'Clock? No, but using a setting on the Pot below 9 O'Clock has not introduced an issue that I would remember either. In a longish post earlier in this thread, I posted a review of the Caliente, specifically commenting on its performance with Shure SE530, Grado SR225, and Senn HD600/650. If I were to have noticed an issue with the pot using any of this range of impedance/sensitivity phones, I would have mentioned it there - with all of that comparative listening fresh in my mind. Speaking of the Pot on the Caliente, I really like its feel. It's very easy to take hold of the Pot, adjust it as slightly as desired and release it to get just the perfect setting. Since where the Pot is actually set to has never introduced an issue for me, I generally don't know or care where it is actually set at. And my brains? I would say that they're not blown out yet. What would you say from reading my posts?

What has struck me about the Caliente is that it is probably the best all-arounder amp that I have ever owned, AND it sounds exceptionally good with the phones for which I mainly bought it: the HD650. In the review/impressions post earlier in this thread, I go through a variety of music tracks and rate the performance of the Caliente as an "A" with the series of phones that I used.

I don't have a mental disorder about the pot's placement in general either. I take your answer that it's not too sensitive, that you get a good feeling of it and have room for error.. Some amps that have high gain, I can't turn beyond 9 o'clock with my Grados and AD2000's. I'm not sure if this case could be solved with a logarithmic pot, not that i had the skills to make such an operation . I've gone accidentally to 10 (Crikey!) with AD2000's and have almost damaged my hearing permanently..

Thanks for your very thorough answer!
I've read the whole thread by the way, just needed to hear it exclusively. Respect! (not in a gangsta way.. though why not?)

It's 'warmness' sounds exactly what i'm looking for. To have that extra weight on notes, while - as you said - not letting the bass veil any of the other elements/instruments of music, in other words, retaining it's transparency and control. Sounds too good to be true. Am i getting ahead of myself?
