new Parasound A21+ vs my old Rotel RB-1080


Parasound is having a sale on siver.  Audiogon moderator just removed the post.

any advice on an A21+ to replace an old Rotel RB1080?  system is MartinLogan ESL-X .  I have an top end tube audio-gd preamp with a PSA-DacJr and Eversolo source.  SVS micro sub.    I think that the Rotel is the bottleneck for clarity.  I recall it being a step up from my Adcom 5400, still warmish but with better bass control.  With the tube pre, I was hoping to upgrade to a strong Class A neutral SS like a Pass or Coda.  but probably never have the budget.  for $1500, do you think it would be worth it?  or too similar to the Rotel

I owned a Parasound A21+ to drive electrostatic speakers and was thinking of selling the speakers until luckily a potential buyer wanted to audition them with his amp. Suddenly I realized it was my amp. The parasound, and most high power amps, in my experience, does not perform well at low power.

The Pass and Coda you mention are in another class. I would expect the parasound to be a step down from your Rotel.

That is just my experience with one amp. Could have been made on a Monday I guess.

Your ML has active bass and doesn’t need a lot of power to drive it.

@soix I may be looking for something the speakers don't have?  when reading about electrostatics, I expected that speed to come out as a crisper sound.  I listen to mostly live- Dead, jam bands, blues and new grass.  in the live experience.  drums and cymbals are tight, they don't sound like thwacking on a cardboard box, cymbals ring and crash.  I previously had B&W 683 towers, followed by ML 60Xti.  dynamic drivers. my car has Focal separates- the inverted dome titanium next to a windshield is incredible for ride cymbals

from the non ESL speakers, I know the warmth of Adcom, the Rotel at 200w was a step up in control.  a 160w Perreaux was cool. I also had a rogue cronus magnum iii that I tried when my CJ PV-12 needed too many repairs.  Pretty certain that thw weakness in the rogue was the preamp.  even Rogue said the RP-1 would be noticeable improvement.  I did enjoy it, but it was time for achange.  the Rotel I had in storage.  I traded in the Rogue for the Vacuum HE1 MK3 (super clear, all balanced).

I like these ESL over the box speakers for their continuous soundstage.  although a bit surprised by the narrowness of the sweet spot.  not beaming, but can definitely tell when not on it.  unfortunately, no good listening room in this house so no flexibility to optimize placement or room treatment.  long 30' and narrow 13' room with picture window on one side and stone fireplace on the other where first reflection hits.  and barely 3 ' from front of speaker to the wall. 

punch from an electrostatic?  I am happy with the bass response, I have a total of 6@8" drivers (two per ESL and two in the SVS micro).  

I admit- went to a show and the big room had Neolith with two huge parasound monos.  best sound I have heard.  it was just such a relaxed presentation (vs strained) sounded very natural.  I then bought what I could afford.
