As for subtle but useful features, I look forward to double headphone insertion and watching a movie on the pc with the wife. Sound is enhanced with no thrown switches. Switches thrown do result in appreciable differences.

 

Thanks for your thoughts.  The form factor is extremely nice and the switches give the amp good versatility, which can make some very technically proficient headphones that don't fit your preference more to your liking.

but I can say some things absolutely:

1- I hear a lot of interference when some one is trying to call me (my phone is Motorola)

2- the Arrow is really portable (I put it in my pocket while going to university)

3- I can't hear any noticeable improvement in SQ of my shure se315 (although I didn't expect any improvement on SQ when I ordered arrow)

4- when I listen to live recording tracks, the sound stage is amazing

5-I'm planning to buy a westone 4r with a 75ohm added impedance to pair with my arrow ( this is why I ordered arrow etysmile.gif)

 

 

edit: do you find the crossfeed function useful ? I just use it on some live recorded tracks.

I haven't use bass boost; but put the treble on " I " some times.

 

1. Yep, and that is the most unfortunate thing about the amp.

2. Very portable!

3. Lower end BA earphones in general don't improve much with many amps.

4. Is the soundstage better with the amp?  If so, that is an improvement ;)

5. Nice, should be a good combo

 

I don't notice a difference with the cross feed on, but then I don't listen to much from before the 70's.

I know - I kept typing 'EPH' instead of 'EHP', but there it is in black-and-white. 

 

Thank you...fixed!

Good to hear.  The hiss really isn't a factor for music playback, but I noted what I heard.  I do have some ultra high sensitivity CIEMs, with the most sensitive being the DUNU DC4 and hiss isn't an issue with my setup.  If you have a quiet source, you may hear the hiss, but it is still doubtful.  I try to mention all the things people may be concerned with, even for tiny % of people that may have a setup that could lead to hiss.

I'll reserve the rest after burn in
one more thing...Mr. Aguilera has been extremely helpful thru this transaction - emails were replied promptly and I was given updates on the order processing, and a surprise on shipping wink.gif
[edit] and of course I post this in the wrong thread doh

 

The channel imbalance is there on mine.  I listen at extremely quiet levels, as low as the amp will go, when lying in bed and every single amp with an analog volume control has had imbalance issues with my high sensitivity CIEMs at that volume.  Not a big issue IMO and as mrarroyo stated (good).

 

And thanks for posting here ;)

I have 5 CIEM reviews I need to do before I review any more amps, and each review takes on average 2-3 weeks...  But, it is an amp I am very interested in hearing.  I did have the RX, I think the original and while it was great with some of my IEMs, it didn't fit help my SM3 much so I sold it.

I get the impression that the Mk3-B, as its now known on the ALO site, is designed explicitly for balanced use, just as the SR71B was - there are cheaper options like the Stepdance for single-ended use - that said, it has had some glowing reports thus far. I like to wait until the initial hysteria has had a chance to die down, which is one of the reasons that I'm still keen to hear the L3 - it doesnt appear to be anyone's FOTM amp, but I have yet to hear a negative re sound quality from anyone who actually owns the amp - form factor and price notwithstanding, it stands out as the very thing I've been chasing : a battery-powered (easily) transportable amp that will power almost anything short of the HE-6. Triad seem to have their production act together now - still not like ordering something from iBasso, though.  wink_face.gif

 

If I can throw in my 2 cents worth re the EHP-O2, having had mine for 6 months, I hold the amp in considerably higher regard than I did in the first month or so of ownership. I suspect that's simply a case of getting used to the presentation, but initially I found myself going back to my other amps when the 02 seemed too brutal with things like YouTube vids and throwaway pop, particularly with the AD900s, but that is no longer the case unless I'm really tired and just want something mellow as background music. I agree with others that the hype around this amp is way out of all proportion to the sound, but it has definitely settled into its spot on my bedside table. It would be interesting to hear it paired with a better source than my MSII - I suspect those YouTube vids might be a bridge too far.   eek.gif

 

When I eventually get another P4, I'm going to revisit my impressions of the O2 alongside iBasso's little marvel. I have a massive soft spot for the P4 as a killer bang-for-buck amp (largely overlooked on Head-Fi), but it would be interesting to be able to DBT the two - stock opamps to be fair to the 02's budget chipset. If memory serves me correctly, neither of your top picks has been less than 500 USD - add Ray's balanced amp at 650USD and the L3 at 800 clams, it soon becomes obvious that there is a place for 'mid-range' amps that fit in between Fiio (good products in their own right) and the top shelf.  Thanks again for the effort you are putting into this thread.   beerchug.gif

Currently listening to Charles Mingus - This Is Jazz 6 and the sound is very nice and involving. The sound has "weight" and authority.

Ah, the Mk3-B is primarily a balanced amp. I did a balanced vs. SE comparison with my CIEMs using the 801 balanced output vs. the Anedio D1 vs. the GAME card (I have not posted it) and found that sometimes the SE won, sometimes balanced won depending on the CIEM I tested it with.  I wonder how much better an amp like the Mk3-B would be than the 801 balanced card as I am sure there are some improvements.

 

And yes, there is room in the mid-budget for amps.  If I only had more time I would love to test more amps at all price levels.  Maybe the P4 at some point!

I am guessing you are referring to the 627 ;)  If so, yes, the 627 really adds a realistic weight to the presentation that is neither overpowering nor unnatural.  Other amps that increase the weight, such as the Arrow, do it in a more upfront way that doesn't sound as natural and integrated.  The 627 is a pleasure to listen to!

post #110 of 277

So is the 627 really just gives 4 hours of playback? (and the battery only 500 charging cycles?!?) That seems poor to me even if the sound quality is the best out there (according to your review...). Have you tried the JDSLabs c421?

 

 

Thanks,.

yea it dies pretty quick and just pops when it goes dud. i think the review is pretty spot on. I don't want to say too much about sq because of my limited experience and lack of burn in at this stage. My impression from reading the other user experience is that ATH CK10 are hard to have synergy with often "sidegrade" or mismatched amp/phone pairing, and the portaphile 627 has definitely improved its performance in many areas. (this doesnt change the fact that they STILL sound good unamped.)

With the 627 and CLAS there's a lot "wow" moments. I have no idea of music describing terminology but the best way to describe it that it renders background instruments with words as: enveloping, airiness, 3d, clarity, and TONS of detail. The wow moments usually happen when the instruments kick in/transitions and all of a sudden you're in a sonic flood. With this said its strength is also its weakness. Sometimes there's too much emphasis on the instruments, you could almost pick out each one playing it's own thing, getting a little distracted. In some songs it takes a little effort to focus on the main singer.

HEy Average_joe, any chance you can modify the table sizes so i can see all the ratings? It's become quite annoying having to open up word and copy and paste it, then go to web layout mode just to read the total quality with sensitive IEM's. and other scores.

That it does (the dies pretty quick part).

 

As far as the emphasis on background instruments, I find it keeps background instruments in their place better than other amps while still giving them weight and definition, so I wonder how much the mastering has to do with the emphasis?

I made some changes, let me know if they worked.

Average_joe does the uha120 pair well with JH-13s?

post #115 of 277

Just jumped on the Portaphile train!!! Can't wait till it comes in.  As a side note, I must say that Cesar has been wonderful to work with.  I don't think it has taken him longer than two hours to respond to anyone of my emails; one of those being on a Sunday at 10pm.  He also shipped the amplifier out the very next day, perfect service!

The uHA-120 pairs rather well with the JH16, so I would imagine it will do well with the JH13.  I can compare to specific amps I own if you would like with the source closest to the one you will use, just let me know.

Thanks for letting us know about the exceptional service, and great to hear you got the amp.  Let us know how it performs for you!

Average_joe, If you could only afford a $200 amp, would you pick the O2 or the Neco Soundlab v.3  for the HD600? (I know you've reviewed the version 2 here). I'm open to any other suggestions as well.

OK, I just A/Bed them with the HD600 and that's a tough one...the V2 form factor is better than the O2, so if you are taking it on the go, the V2 is the clear winner IMO.  From a sound perspective, the O2 is cleaner, especially in the treble area, but the V2 has more detail/resolution and slightly better dynamics.  If you want a smoother, more pleasant sound, the O2 wins, if you want to hear more detail the V2 wins.

Thanks for taking the time to do that; I really appreciate it. Unfortunately, you said exactly what will make it impossible for me to choose! :) I contacted Neco to see how the V3 was to improve upon the V2 maybe that will help me choose!

Well the portaphile 627 will be delivered at some point today, I will post my impressions for those interested later this week/weekend.
