Requesting opinions about 4 specific amplifiers


Greetings Audiogon community,

I am requesting your input about four specific amplifiers in a particular price range and how they may, or may not, pair well with my Dynaudio Confidence 20 stand mount speakers.

My room is 20' x 16' and does have wall absorption treatment. I do not listen at high levels, typically in the 75 to mid 85 db territory. 

I currently own a Luxman L-509X integrated amplifier, which is probably the best integrated amp I have owned to date. However I am wondering if there is a better amp match for my Dynaudio Confidence 20 speakers, and so am considering moving to separates. My budget for the amp alone is in the preowned $4K to $5K range.

Here are amps I am asking for your input about ;

-Simaudio Moon 860A V1 (Dynaudio dealers seem to endorse Simaudio)

-Pass Labs X150.8

-PS Audio BHK Signature 250 stereo (PS Audio has dropped the price on new amps in their closeout sale)

-Parasound JC 5

I realize there are many, many, amp manufacturers, and that of course if I reach a bit higher I could consider Ayre, or Aesthetix, or Coda, all of which interest me, but seem to stay outside of my budget. 

I wish I could side-by-side compare or demo all of these amps, but unfortunately it is not possible. I am looking to your experience to help in any way possible.

Thank you!

<.005% THD+N performance, .1dB flat from 3Hz to 50kHz, full differential.  Half the cost of Mac and only 27 lbs for 200W.....something to consider....

other ideas: replace integrated with integrated?  Simaudio is wonderful stuff; Moon 641?  Also, Modwright KWH 225i (hybrid).  I suspect both would sound a little warmer than your Luxman.

Personally, I feel the Luxman 509 is a little analytical to my ears, especially with those Dynaudio speakers. I agree with those posters who recommend a tube preamp to warm things up.

I love the look of the accuphase, and people who’ve heard them seem to have great things to say about them, but they just seem overpriced in the USA. Their USA distributor seems hell bent on price gouging. It’s a shame. 

Hello @jpipes , so many choices and opinions!  While never with your speakers, I have owned and quickly sold BHK 300’s which were noisy and dull.  I have owned and sold Parasound JC1+ monos, which were also lacking on sparkle.  I have demo’d the Luxman, which, I did not prefer..  I have heard many Pass amps, which I found warm and pleasing, but not magical for me.  I have not had the pleasure of Coda or Sim / Moon or Accuphase but bet they are good.  I have had the Benchmarks in my system and I thought nothing special except small and less expensive.  For me, the clear winner was Audionet amps.  The entire line shines but the magic really comes starting with the Max amps.  These were well more resolving in a pleasant way than anything I had tried or heard.  Much more sparkle on top, but in a non fatiguing way.  Very full spectrum.  They occasionally can be seen used for around 18k, more than most discussed here but to me so worth it.  I now have my Max’s upstairs, and have the  amazing Heisenbergs in my reference system.  All here is just my opinion, but I do recommend you listen to Audionet.
