There's another super crazy high power amp card for HM-901/HM-801 to be available in 2014 and that should be called U235 card with whopping 6V output

http://www.erji.net/read.php?tid=1433688

How do we actually know whether that's too much power to damage another amp's input or not?

Besides, is triple-amping causing any potential problems?

HM-901 headphone amp card > KM01-BRASS > ALO The International

About your question I will answer by tomorrow

I am sorry , I have not tried your dsd music file to drive my abyss

Rudi do yourself a favor and audition or get an AK120-S. It is just sick ;).

We could also take advantage of the balanced output of RWAK120-B and go for perform something like this:

 

RWAK120-B > 4-pin TRRS to RSA balanced cable > Cypher Labs AlgoRhythm Duet > RSA to RSA balanced cable > ALO Rx Mk3-B+ > balanced headphone cable

 

Both AlgoRhythm Duet (preamp) and Rx Mk3-B+ (amp) are pretty much having the same size so the stack should look quite neat:

 

4.5 x 2.8 x 0.9 inches ; 7.2 ounces

 

http://www.amazon.com/Cypher-Labs-AlgoRhythm-Headphone-Amplifier/dp/B00H9L2B28

 

2.9 x 4.5 x 0.9 inches ; 9.8 ounces

 

http://www.amazon.com/ALO-audio-ALO-2217-Mk3--Black/dp/B00DZVY53O

 

Of course we could also replace RWAK120-B with AlgoRhythm Solo -db plus another excellent source such as Sony NW-ZX1 etc. Or go completely single-ended if we prefer the sound of KM01-BRASS.

 


 

Heck, what if we just do a double whammy by stacking a pair of KM01-BRASS instead so balanced output could be created just like this?

 

 

 

Not an easy task to pull that off IMHO but still worth a try?

My friend has planing to do like your idea on his O2
I will let you know if already finish his balance O2
post #8780 of 13876
Is that the same friend who helped you with both iPhone 4S mod and DB-2 mod?

I wonder what would it costs to build a solid brass case by your friend versus getting that done for O2 with 3D printers. Then the case could be gold-plated afterwards instead of always wrapping the amp with a piece of cloth.

Something similar could be done for the housing/chasis of an iPhone or Sony NW-ZX1 etc. Instead of 24K gold like the ones from Gold & Co. London, we'll just go for solid brass if that were actually changing the sound.

Rather impressed with this R3 dual dynamic by Brainwavs coming out my Studio.
The rather strange looking acoustic chamber gives them a unique soundstage experience.
Their aluminum housing also seems to reflect in their timbre. 
Not bad at all for $129 offering. The fit may not be everyone's cup of tea but if you can get it right you'll be rewarded.

+1! I should be able to source two matching amps as well... 

post #8784 of 13876
+1 does splitting require the source is a balance line/phone out?

Totally agree was pleasantly surprised by them

I sold my Grado SR60's a little while ago to a dear friend from school.

I do miss them but its nice to see they've gone to a good home and introduced another friend to the hobby :) 

 

Sorry about your wallet Dave! lol :P

It might make just a bit more sense once we check the back of that amp with 3.5 + 3.5 = 4-pin XLR below

I'm still not sure about how the source should be handled. At least we could tell that an extra 3.5-mm output was found in addition to the 3.5-mm input and 3.5-mm headphone jack.

 

Another interesting design here

A fun setup for me would be having something similar to the affordable yet fantastic Neco V4 so I'll keep 4 of them at home, 1 pair as preamp and another pair as amp for driving hungry cans. Then pick only one of them whenever I decide to bring something away from home and still having plenty of power.

Where it all started.

 

No expensive amps. No external DACs. No overpriced ICs. Just an iPod and a pair of on-ears (granted the first time, they were PortaPros...)

Those were the days, before addiction kicked in with a healthy wallet in hand. Before curiosity began playing chess with audiophile devils.
