Here's the criteria. Less than $250 Equal or better to Schiit Audio Magni 2 Uber for both quality and power (50 ohms: 1.2W RMS per channel). Something bigger than Magni 2 Uber but still less than 10" wide Two primary headphones are Sennheiser HD580 and AKG K7XX Massdrop Limited Edition...

  Only source is my computer so not really an issue.     I really do like the NFB-15 but I'm worried about size.  I need to measure the space when I'm back in the office on Monday.

Going with the dac/preamp/headphone amp route I see two contenders.   The Audio-GD NFB-15 and a Schiit Modi 2/Magni 2 Uber combo.  I'd keep using the TP30 but only to power the speakers.   The NFB-15 has a little more power, more flexibility on the output and is a single unit.  It's a lot...

    That has serious potential.  Price is low enough that I could find a separate power amp for my speakers and put it under the desk.

Starting to think it might be easier to find a preamp/headphone amp and then just have a separate power amp under the desk.

Yeah, those are beautiful amps but too expensive and honestly too big.

The element is interesting.  Still prefer a single unit but I may be able to fit two, especially if I can stack.​

Hmmm, been looking around I did find this one.  I have to admit, being able to get a tube amp hybrid has some appeal. 

Have to admit, that is a sweet amp but yeah, more than I really want to pay.  I wish the Musical Paradise MP-302 was still being made.  That's what I run at home and I prefer it to the TP30.

No offense but I didn't ask for a complete new setup, I asked if a specific type of speaker/headphone amp was available.   I like the DT990s but if I needed to switch I've got a pair of Senn HD580 and AKG K7XX Massdrop edition at home.    I most definitely don't want new speakers as the ones...

If possible I'd like to keep it under $500.  Main reason I was looking for a single unit is that this sits on my desk at work and I don't have a huge amount of space to work with.

So I'm in my 50s and have some hearing issues.  Not to the point where I need a hearing aid but my hearing is definitely diminished. I’ve got a pair of Beyerdynamic DT 990 PRO 250 Ohms headphones being driven by a Topping TP30 amp.  Source is my computer.  Even when I have the amp and computer...

I'm fine with a class-T, would just like some specific recommendations.  For example, I thought about a Topping TP41 but in doing research, it looks like the amp used for the headphone section isn't that great.

I've been a big fan of Musical Paradise's MP-302 Class-D Mini Amplifier.  Quality small size headphone amp that I could also use to drive speakers when I didn't want to wear headphones.  I liked it so much that I wanted a second one for the office but now they are discontinued.   Here's what...
