Amp recommendations for Joseph Audio Perspectives2

I bought a pair of Joseph Audio Perspectives (Graphene 2 upgraded) and they will arrive next week. I am looking for amp recommendations now.

Currently I am using prism sound DA1 as source, Schiit freya + as tube pre. I also have a CJ pv5 tube pre and really enjoyed the Conrad Jonhson midrange presentation. I am thinking of upgrading the pre to higher end CJ line in near future (like a used CJ GAT?).

Previously I was using only SS amps with tube pres in ATC speaker system since they have a hard load. I tried a bunch of SS (Krell 402e, Pass xa30.8, Nord nc500, Benchmark ahb2, Mivera 1200), they all sounds nice in their own way but I feel the piece that makes the most difference in my system is the CJ pv5 tube pre. It brings out the 3d soundstage and liquid mids that I was looking for with each amp it paired with.

I love rich liquid golden midrange. So for amp, should I use a tube amp to achieve this goal? I searched around the discussions and what is available in the used market and a couple that interest me now are:

VAC Renaissance 70/70 Mk III
Jadis defy -7 Mk 2
VAC Phi 200
Conrad Johnson Premier 12 (NA in used market now, only a premier 140)

I prefer stereo unit to monoblocks. It will be even better if the amp can produce less heat. I live in CA and it is pretty hot in the summer. But if I have to go that route to get the best sound I want, then it is what it is.

Any recommendation (not necessarily to be the amps mentioned above, can also be ss) or advices are welcome.

For the amp stand, check out Symposium Acoustics; Ultra Platform, Pro Ampstand.  Those amp stands can handle a nearly unlimited amount of weight.  And when combined with Rollerblock or Rollerblock Jr+ it becomes an excellent mechanical ground system for amp vibration drainage.  Truly a state-of-the-art amp stand, and though not inexpensive, at much less cost than some of the other highly effective amp stands available.  I hope this helps you.

I was looking at the rack in this listing https://www.audiogon.com/listings/lisa4309-vac-valve-amplification-company-renaissance-70-70-mk-ii-tube and it looks great to me. Any one know what model is it? Thanks.

I would look into Pass Labs class A amps (XA30.5 or even better XA60.5). They sound magical with Josephs

I have not heard those specific models.

In addition to performance,

I buy things I like/love every time I see/touch them, power on or off. That puts my brain in a more receptive state for their superior performance.

That Vintage MC275 is a beauty, I much prefer it to the CJ. I would not want that beauty down out of sight if I could arrange it.

I tore my Meniscus pulling my McIntosh SS Amp, MC2250 80 lbs, out of a low shelf, a pair of compact mono's have an ease of movement advantage. Location: think about how two people could put heavy piece in place together.
