Powerful Tube Amp for SF Strads?


I am looking for recommendations for a powerful tube amp for my Strads. A powerful tube amp which truly excels at palpability, musicality but also has very good bass control (though bass control is not as 'mission critical' to me as palpability).

My current amp (see below) sounds great to my ears!...but runs out of steam much too soon.

My system today:

Zanden 5000S DAC
CJ Act 2
CJ MV60 (EL 34 tube)
SF Strads (4ohms, 92db sensitivity though impedence does dip to 2.5ohms)
Velodyne DD-18 (run in parallel)
Transparent Ref/Ref XL cabling throughout
Purist Audio Dominus PC

In addition to recommendations, any thoughts are welcome on Wavac, Audio Note, Zanden, VTL, CJ LP275...or monoblocking MV60 (EL34)? Thanks!

Wow...Thanks Sirspeedy. Sounds pretty incredible. I will say the Zanden 5000S captured me, after only 5 minutes. I had struggled to do the DCS Elgar Plus 3x before ultimately deciding it was not for me in spite of how great it was.

I will look into the 9600s.

And yes, Downunder the Bernings are 30K. Nevertheless, i am someone who likes to listen to pieces like this so that either a) i determine i am going to keep looking, b) i understand the totality of what is achievable today, c) i decide i am either going to do something crazy like get them, or wait until a more sensible time to spring for them.

I bought my first boombox in 86, my first system 93-96, and have started the first upgrade in '05-'08. i have upgraded each component ONCE, and do not expect to look back for another 10+ years.

Thanks to the A'Goners, i have many things to audition before i decide: at the moment,

Wavac
Berning Quad Z
CJ LP 275
Zanden 9600

will be an adventure for sure!
Consider Audio Valve challenger 180 watt class A, built like a German tank. Amp, tubes fully protected, auto bias, tells you if tubes are weak. Sound is amazing bass best Ive heard out of a tube amp. Can run differant tube types. Can drive most any loudspeaker including electrostatics
The Audio Valve amps are indeed superb and I should have included them in my discussion (I usually do, but forgot). The 400, I believe, is one of the rare high-powered tube amps that truly sounds good. They will be expensive with the current exchange rate (assuming you are in the U.S.).
has anyone heard the Pass XA.5 upgraded class A amps??

I wonder how they would go with my Strads and how similar they sound to nice tubes in the upper frequencies.
