Amplifier Upgrade Decision


Hello,
I need some help/feedback with regards to upgrading my power amplifier for 2 channel music. My current set up includes following components
1. Source (Digital)- Oppo BDP-95
2. Source (Analog)- Clearaudio Concept Turntable
3. Pre-Amplifier- Parasound Halo JC-2
4. Pre-Amplifier- Parasound Halo P-7 (using the phono interface for playing the turntable)
5. Power Amplifier- Parasound Halo A-21
6. Front Speakers- Aerial Model-7T
7. Power Cable- Nordost Heimdall 2 and Red Dawn 2
8. Interconnect Cable- Nordost Frey 2, Heimdall 2 and Red Dawn 2
9. Speaker Cable- Nordost Red Dawn 2
10. Wall Receptacle- Furutech GTX-D NCF(R)
11. 2 Dedicated 20 Amp (10 AWG) circuits feeding the entire system
12. GIK Room Acoustics Bass traps/Diffusors
13. Room size- 16’ X 12’
This set up sounds good but I wanted to take it to the next level and wanted to upgrade my amplifier to a better 2 Channel amplifier or a set of mono-blocks. I love Class A/AB sound and would like to stick to this technology. My choices, not in any particular order, are
1. Upgrade to a Plinius SA 103 (125 W pure Class A per channel) and use it as a 2 channel amplifier
2. Upgrade to a set of Class-A mono-blocks. My choices, not in any particular order, are
    a. Parasound Halo JC-1
    b. Pass Labs XA-60.8
My budget is around 10-12K.

I know everything is system dependent but I would love to hear your opinion on these amplifiers before starting on product evaluation.

I am also not sure if my mono-block amplifier choices would provide significant value add from a sound perspective over the Plinius or any other good quality 2 channel amplifier at this price point. So I would love to hear your feedback on this point as well.

You should consider the Aesthetix Atlas. You could buy mono amps used in your price range.
After listening to a few different PASS, Threshold, Stasis amps popular in my area of NorCal over many years, a few local guys started trying other amps for different sound tastes; one is the Cary SA-200.2. I bought the new Cary 200.2 solid state amp just over a month ago to compare side by side to some of my tube amps. With the right sources, interconnects, and compatible speakers, the new Cary SA-200.2 stereo or larger monoblock amps are really nice sounding for the $ and then some. I put a nice Cary SLP-98 tube preamp in front of my SA-200.2 solid state amp, it really sings smooth after 150-200hrs of break-in. Sound can be tuned using softer or brighter interconnect cables. Just went from silver plated copper back to pure copper interconnects on this new setup, and wow. It’s giving my tube amps a run for the money. Huge, deep base, nice soundstage, very dynamic, and more midrange with good copper cables. I own just one Cary SA-200.2 stereo amp, and its plenty at 200w/8ohms, but I’m running mine at 350w/4ohms. Great value too, my .02 cents. Super bang for the buck $

Ayre MX-R in old config
or a VX-R might get lucky and find a used Twenty series in your budget
the Aesthetix stereo and mono are awesome amps IMO
