That's kind of frustrating but possibly true... In my experience, K340s require a bit more volume than 600 ohm DT990s to reach the same loudness, but that doesn't mean optimal performance...the Emotiva a-100 really opens it up, but I don't want another bulky speaker amp on my office desk. I was looking for a DAC+amp combo that's powerful enough and reasonably compact. This seems to be quite a challenge now...
Thanks Crhis J!

How about something like this Topping T-30 15WPC? Small, attractive, and even has a DAC (no idea the quality). Topping amps are inexpensive, but regarded well for what they are. I'm assuming you have speaker connections on your K340 if you are already using a speaker amp.

Or if you'd rather just an amp, the TP21 ups the power and nixes the built in DAC for less money:

In my experience, you're not gonna get the same SQ experience from a headphone amp on a few of the very power hungry headphones. I don't think you'll find any that have the power for them.

Thanks Maxvla! I know this is taking you guys off-topic, sorry! The topping amps seem to be a very hopeful option. I will look into them carefully.

I must agree that the K340s is one of them. 

 I might be one of the few guys today still playing with these... Thanks!

Honest question: I've dropped my HPA-2 down to $225 in the FS forums and continue to not really get any interest. Is my pricing reasonable? Or is this just not a desirable amp at the moment?

I think I've owned 2 or 3 pairs. There is something really special about that headphone.
 
Something to note, in case you didn't know, is I believe all topping amplifiers run on a tripath design, meaning you do need a balanced recable on your K340 to use them (someone correct me if I'm wrong on the tripath).

 

[Maxvla]

The Topping amps I linked to above have standard speaker outputs. I assume since he has the K340 in use with a speaker amp already, he has reterminated to bananas or something.

I think it's a reasonable price. Dunno why it ain't selling man.

Let's just say I sold my HPA-1 for $150.
Does yours have the USB DAC?
mine did not.

 

[TooPoor]

Yes, it does.

I think the M-stage HPA-1 was such a FOTM type amp that about 6 months ago a ton of them were selling used.
 
I think you might want to include that it's a "USB DAC" and not just "USB". If the DAC is decent seems like a good all in one for a computer type rig.

 

[Chris J]

Yes, it does.

Hey, why are you selling your Bushmaster?
I love mine!

 

[TooPoor]

I love mine as well! Just looking to go with something balanced for a future balanced setup. Or if I like it enough with my newest (incoming amp = La Figaro 339) then I'll keep it!

I understand.
I was thinking about getting a Matrix Quattro amp myself, so I'll need a balanced output DAC to go with it.
