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.

CJ says 200wpc, 135 lbs, 1b is the latest version

but owners manual says 150 wpc

in any case, more than enough power for those speakers, and more for future speakers

personally, I would go with the McIntosh, 75 wpc also enough for those speakers

@elliottbnewcombjr Thanks for the info. I just grabbed a VAC renaissance mk5 tube pre from ebay at what I believed a good price. Now I am leaning between the mc275 and VAC 70/70. They are relatively similar in power. Do you know how different would this two sound?

I know you said you prefer a stereo amp but man these Air Tight ATM-3 mono’s would drive your Pulsar’s to perfection and used they are right at your $7K budget mark. No connection to seller just a former Air Tight owner, ATM-1 a long time ago great amp.

Unless you wanted an integrated the Line Magnetics are not what you are after as a power amp , the preamp section of the LM integrateds are not taken out of the circuit when you use a separate preamp. I have a LM 518IA so I know firsthand
