ALO Audio RXMKIII Balanced Portable Amplifier Impressions - Page 50

post #736 of 914

How does it compare with 627x ?

I'm not looking for power, but dynamics and neutrality.

Does anyone have any experiences with the C5 that they can compare to?

Incoming!

 

I have the C5 and the RxMKIII-B+ will arrive this weekend. Please note these are VERY different amps.

 

I can try make a comparison using my Earsonics SM64 v2. Would that be OK? Other good headphone I could use is the Hifiman HE-500, but I think that would be unfair with the C5...

Of course, thanks Themad! :gs1000smile:

I wanted to chime in and say that I have been using the RxMkIII B+ since last August, when I bought it from ALO, during a visit to their headquarters. I initially used UE900s, but have since switched to AKG3003s and an iPhone. I have never had the hissing problem, but the 3003s aren't as efficient as other IEMs, so it may not be the toughest test for the Rx.

I have also used Audeze LCD-2s and LCD-3s with it and I have been shocked at just how good of a job that it has done. I thought that although others had claimed that it could drive tough headphones, it was still JUST a portable amp. I really enjoyed several evenings listening to the ALO/iPhone/LCD-3 combo.

I have since sold the Audeze as I am saving up for a Stax combo. I will probably end up selling the ALO as well, to help finance the big rig, but I will definitely end up with an ALO amp again, once I can afford it. For me the perfect addition to the ALO RxMkIII b+ would be a built in DAC section that was as good as the Resonessence Labs Herus.

That would be awesome! Especially not having a third box to carry in my pocket : )

I'm new to head-fi gear. In November, I purchased this rig iPod -> CLAS-dB -> RxM3B+ -> LCD-3 (balanced) for a road trip around New Zealand. I noticed a hum/buzz, which was only slightly annoying with classical music with the bass boost turned on. With the bass off, the hum was much worse and almost any classical music almost unlistenable. 2 weeks ago, I changed the LCD-3 for the LCD-X and the problem has become much worse, I presume because the X is more sensitive. It's a buzzing rather than hiss which people describe. Interestingly when I listen to it while its charging, it completely disappears. It's gotten to the point where I can't listen to this combination anymore as the buzzing is noticeable in all classical music and quieter passages with all other music. With the bass boost turned off, the noise is several times louder and the amp is completely unlistenable. Any thoughts on what the problem might be? I also have the Vorzuge Duo which is whisper quiet but I would prefer the ALO if this issue could be eliminated.

I would contact ALO on this one, since your device is under 1 year old.  Dumb question, what gain setting are you using, and have you tried all 3 settings to check for the hum?

 

Also, maybe make sure your S/B switch is seated in the correct position, as I would expect so noise if it was stuck between...

Thanks. I would bring it back to the dealer but I'm stuck in a more remote part of Australia at the moment. The hum is present at all gain settings and doesn't seem affected by which setting is used. And whether in S or B mode, I've tried both with the switch correctly positioned.

I just upgraded from the MKll to the MKlllB+, 1st impression:  Significantly more power. There are plenty of desk top headphone amps with less juice. My HD650 is my office HP and they seem to pair better with the medium gain, high gain knocked out the ability to tweek the volume.  So far I haven't heard any hiss or hum, but my understanding is this may be more of an issue with IEM's.  

 

Over the weekend I'm going to pair with the HD800 and T1 with the MKll3B+.

 

Any thoughts about a a choice of balanced 4 pin mini as an out to HP's?   

post #747 of 914

You will probably really like the T1 balanced. I can't give support for a certain plug style or company but I can say with enthusiasm that dynamic headphones and balanced wiring were made for each other.

post #748 of 914

I'm actually not massively thrilled with the synergy of my HD650s with my Mk3 B.  It's got the power, and I also use the middle gain setting.  I prefer my HiFi-M8 for those particular phones.  But I do suspect you will be real happy with your HD800s and T1 with this amp.

 

I had a cable made with the Kobicon (sp?)/RSA plug as an end, from BTG Audio.  And I think he would sell you an end if you want.  But i don't think there are options/multiple brands of his connector, like there are in other balanced ends...

I am thrilled with my HD650's and CLAS -R/Rx Mk3 B+ /Silver Poison Toxic Cable (balanced) combo. I use the high gain setting and color the low end about 20% of the available bass extension. Expansive soundstage, impressive separation and nice dark space. Beautifully musical. Too bad I can't wear them on the trams and metros of Prague without disturbing the general public. That's why I decided to order the "big dogs" from Mr. Speaker. The Alpha Dogs with a Double Helix balanced terminator cable should really light up with the CLAS/Mk3 B powering them. Too bad there's a 6-8 week back order on them. Soon they will be mine, all mine (add sinister cackle here).

post #750 of 914

I appreciate all the above advice.  I decided to balance the HD650 as it is the HP I use at my office thus with the MKlllB+.

 

If I like the sound I may end up balancing the HD800/T1, but then I'll have to grab a balanced Amp., damn this hobby, a never ending wallet drain.
