Audio GD SA-31 head amp/ preamp . A powerfull Head Amp with Diamond Difference design . - Page 24

post #346 of 433
Has anybody else tried the SA-31 with the Beyer DT-48e?

IMO, a great combination for vocal and choral (tremendous transparency and lack of grain).

is it possible to use a universal remote with this amp?

It doesn't seem to be possible with an ordinary Logitech remote or similar. There's an old thread about Audio GD remotes here:

Reading this thread I realized there isn't a whole lot of information about how the amp actually sounds, especially compared to other amps.

 

My own very, very brief impressions:

 

Compared to the M-Stage, I found the SA-31 faster, brighter (neutral?), with a larger soundstage and much more powerful, yet controlled, bass. I preferred the M-Stage with Denons, but have preferred the SA-31 with everything else (particularly HE-500, T1).

 

Compared to the Bottlehead Crack, obviously the SA-31 is much, much better with the HE-500s. In fact, I find that to be a very good, highly recommended match. With the Beyerdynamic T1s I prefer the Crack. It sounds a little bit more open, a little bit more detailed, but still in a warm-ish, fluid way. Still I sometimes leave the T1s plugged into the SA-31 for a couple of days and find that I enjoy it a lot. Again the bass is very powerful and controlled, and the upper treble a little bit easier on the ear (the upper treble can get tizzy with the Crack + T1 for me).

 

Overall, I think the SA-31 a very versatile amp, brighter and faster and more dynamic than the M-Stage, but still a sound with great body and sweet highs.

Sorry, didn't notice your reply.  Were you able to try out an apple remote?

Yes, I did. It didn't have any effect on the SA-31, which is good since I'm using the remote with my Concero DAC.

Depending on the amount of hours you have on it, I find things change a bit with more use- particularly the openness and treble smoothness on the several AGD amps I have owned/own.

Plenty of encouraging feedback in this thread, and I like that some of you compared the amp to the M-Stage which is helpful.  Still no SA-31 versus a C-2 variant?

Well, this is the only piece of info I've found, courtesy of MLE, from the Compass2 thread:

 

"I wouldn't give up my Compass 2 for any other amp/dac in their price range. Hell, I downgraded from the SA-31, and I'm perfectly content with the Compass 2."

He also said [but for some reason I can't find that anymore] that the C2's midrange might be a smidge more refined.

The SA-31 is bit more musical and warmer it seems.

 

That's all I got.

The SA-31 worked better for me than the built-in amp in my NFB-27 - which is between a NFB-6 and Master-6. The Compass 2 is probably not up to par with the NFB so even less so with the SA-31.
That's with Hifiman headphones which benefit from a warmer amp (SA).
MLE likes warm/dark headphones and has a strong bias against more expensive gears, so I'm not surprised the compass worked better for him.

FYI, Compass 2 has a very similar amp to the NFB-28's [which is a step down from the NFB-27] which has a similar amp section to the NFB-6. The C2 and SA-31 iare built around a single ended design while the NFB-27 & 28 are built around a balanced design so they're not on equal footing if you compare them SE. Also, between NFB-6 and Master-6, that's a pretty broad range, isn't it? 400 vs 1500 is quite a jump there.

Also, I am not sure to what degree HFM benefits from a warmer amp [or source] but I am about to find out. Some say the C2 is slightly warm, others say it's slightly bright and some say it's neutral with equal bass and treble extension... I for instance found the HE-6 w/ a warmer source a bit dull [but still great, don't get me wrong], hence going with a neutral-ish source this time around.

Also HFM 4, 5LE & 6 are the three hardest to drive headphones around [pretty much], not sure to what degree it is warmness or also the raw power output where the 500/560 or 400/400i isn't nearly as demanding.

Well, I'll find out soon but it seems the difference between gear is often exaggerated around here... 

Just saying and IMO.

 

Not in disagreement, just pointing some things out :beerchug:

As is power requirement for certain phones...


How do the buttons on this amp work in terms of convenience compared to a big volume knob? Seems like it would take a while to reach preferred volume and constant pressing/holding might make the buttons not last as long as a potentiometer.

Hard to say, I always used a potentiometer [either analogue, or just as a digital volume control "knob"]

I was comparing NFB-27 balanced vs SA-31 single ended (with NFB-27 as a DAC, in SE) so that reinforce my point.
In the end, all that matters is that you're happy.
