The most neutral amp I’ve heard in my system is the Liberty Audio B2B-100 made and sold direct by the designer of PBN Audio. In addition to sounding exceedingly neutral, it is excels at throwing a large 3D soundstage that I think would really work well with the Pulsars. With your budget you could even get monoblocks, which are said by the designer to be a good step up sonically, and you have a 2-week period to try them at home that is great to have.
Similarly, the D-Sonic M3a-800S is very neutral and quite a bargain at $1475 and offers I think a 3-week trial period. This amp is said to punch way above it’s weight and price sonically if you read the reviews so could save you $$$ if it knocks your socks off.
While these amps are Class A/B and Class D, respectively, if you’re looking for something neutral but with a little more tonal depth the Clayton Audio S40 is a Class A amp in your budget that I’d think would sound absolutely sublime with the Pulsars. Not sure if they offer a trial period, but it’s well worth a call to check it out.
If tubes are an option, the Rogue Medusa has a small tube in the input stage but Class D amplification and is up there with the Liberty amp in its neutrality and soundstage capabilities. For a tube amp, I think a used Audio Research Ref75 SE would synergize magically with the Pulsars.
I heard the Pulsars at a show where Jeff had them paired with I think Bel Canto Ref 500M amps and they sounded fantastic and changed my opinion of digital amps. JA has also shown with Hegel but I’ve never heard that pairing personally although the reviews were very good so yet another good potential option.
Ok, brain dump over. With the wonderful Pulsars I’m sure any of these amps will sound incredible, so it really comes down to your personal preferences and how much you want to spend. Anyway, hope this helps, and best of luck in your search.
