Amplifier upgrade advice under $2000


Hi!  I have a new pair of speakers on order and want to upgrade my power amplifier to be ready when they arrive.  My current system is Klipsch Heresy III, Onkyo M504 amp, MiniDSP SHD preamp/streamer/room correction, and SVS SB12 sub.

Scheduled to arrive in December are Ohm Walsh 2000.  Research indicates these like a lot of power.  If the Ohms don’t work out I’ll shop for a used B&W 804, so still probably needs good power.

So, with a budget under $2000, wondering if I can get something that sounds significantly better than the Onkyo.  Used is fine.  Brands I have seen come up in the price range are Classe (ca-150), Vincent (331MK), Krell, PS Audio, Parasound, Bryston, etc.

I want to know if this would be a significant upgrade in this price range.  My sense is that brands like Rotel, Adcom, Emotiva, etc. would probably not change the sound all that much.  I also have a Crown ps-400, for example, that sounds pretty much identical to the Onkyo.

I recently tried out a Rogue Atlas Magnum tube amp.  It sounded great with the Heresys, a definite upgrade. Unfortunately  it created a loud speaker hum that I was unable to fix.  But it did make me crave the tube sound.  But it seems like finding a high powered tube amp to work with the Ohm Walsh is going to be challenging.

Sorry for the rambling, basically, is it worth spending $1-2K on a new amp or should I wait until I can get into a higher price range before ditching the Onkyo (which has those awesome green meters!).  Thanks!

another option is W4S integrated

Underwood HiFi has a super sale on one. Definitely worth a look

OP - I know there’s a lot of responses but let me add my .2 here - used Parasound Halo A21 might be good for your Ohms or if you choose to go the B&W way. They are solid amps and it’s easy to sell them when you choose to upgrade. You might not loose a lot of $$ when reselling.
Save yourself some money and get one of these amps.

Bryston 4B

Or if you're brave (but probably you aren't), you could build a pair of VTA M125 monoblock tube amps (120 watts each).
