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, Downunder...please let me know if you listen to them!!! It is tough/impossible to get CJ in UK where I am.

Thanks, Larryi...have read your posts and learned from them. I will try to look into Atmaspheres here in UK.
Thanks, Larryi. I've seen your posts before and learned from them. I agree with you on Strads. Compared to Wilson Grand Slamms or Maxx 2s, the Strads are more about "feeling the roisin of the violin strings' than dynamic attack and speed. I prefer my Strads to the Maxx2 because while I care about hip hop, Deep House and orchestral, I listen most critically to jazz, female vocals, and string quartets where the emotive feel of the Strads is remarkable. That said, the Grand Slamms are in their own league.

Thanks for your advice. I'll look for Atmaspheres in London....and hope the Berning Quad Zs (also OTL's) will be a good match.

Lloyd,

I too really like the sound of Strads. I hope you find an amp that really works well for you. The Strads do not strike me as being particularly tempermental so you should not have too much difficulty finding a good match.

Let me make it clear that I have not actually heard an Atmasphere amp with this particular speaker, although I've heard and really liked their amps in general. I've also heard, and liked the Joule OTLs. The Joules struck me as being warmer sounding (richer upper bass), but the particular unit I heard had problems with bad tube sockets (caused an intermittent, but extremely loud BANG), so I can recommend Joule on sound quality, but I would be concerned about reliability.

I am generally partial to OTLs when it comes to higher power from tubes. I personally have found some higher powered pentode tube amps to have a brittle edge to the sound and a "glassiness" that is worse than most solid state amps. OTL's can sound a bit rough and tumble and they may have a bit of brittleness too, but, the compensating payoff with OTLs is their unmatched liveliness and vividness.
The top line VTL monoblocks--the Reference or the Siegfried. This is the best-sounding, most seductively addicting and at the same time most dynamic amp I have *ever* heard.

They give you the best of everything: Magic of tubes, wickedly powerful, and regulated by a complex solid state circuit that maintains proper bias, speed, and linearity.
Have you considered the McIntosh 2301 dual mono pair?

They come straight to mind when you say powerful and tube in the same sentence! :-)
