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.

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.
@elliottbnewcombjr Thanks for the advice! Years ago I used to have the 135lb Krell 402e amp on a cabinet. I eventually installed wheels on the supporting cabinet after my back starts to hurt when moving the amp.

So I just ordered some wheels for the salamander cabinet and racks, just to save me some back pain.

I agree the appearance of equipments plays an important part! You just can’t take your eyes off certain gems.
Is 75 wpc enough for those speakers? I agree, talk to Jeff.

I had the Infinite Slope Crossover, I don’t understand how it would make any difference to placement. They were the most measurably accurate speakers I’ve ever owned, enjoyed them for many years, driven by 300wpc SS (they didn't need that much, it was a phase I went thru, 35 wpc tubes drove them well also)

I missed and now prefer my horns and 15" woofers, and back to tubes, JSE’s at my son’s house.

They were heavy, came on wheels, rolled forward and away from the corners, toed in.

I have my preferred location(s). I often talk about how a very small adjustment to balance can make a surprising difference.

Last night, playing Norah Jones, 2lp set, 2nd lp recorded live, after a while, I adjusted my toe in outwards some, it made a very nice difference. Last week, imaging was un-naturally weide, I toed them in some, bingo.

I’m a big fan of heavy speakers on wheels, pushed back when space needed for large family gatherings; pulled out the pre-determinned distance from rear and side walls for listening, and situational toe-in.

I use 3 wheels, (two front and 1 rear) so the weight per wheel is increased, and no wobble/vibration issues anywhere I move them. They can tip during movement, so I put two blocks on the back corners, just above the floor surface normally, but if they start to tip, the block stops any tilting movement. Not as important with my current monsters, more important with the taller JSI Infinite Slope Model 2’s, they came with 4 wheels, I changed to 3 and rear corner blocks.
@elliottbnewcombjr Thanks for sharing. Do you know if there are wheels options for the JA perspectives? I have isoacoustics GAIA feet to put them on my floors but it would be nice to have wheels installed. 

I ordered a VAC renaissance 70/70 mk3 to match the vac renaissance mk5 pre for the perspectives2. Will see how it goes.
