AR Ref 600s Best for Genesis2?


I'm looking for the best tube amp for my Genesis2. Now using four monoblocks of VK 60s. The power now are just adequate but lacking the headroom needed for big orchestra.
How do you think about the Audio Research Ref 600 driving the Gen2? Will I sacrifice anything from the VK 60s?

The Reference 600s will raise the temperature in your room by 20 degrees. They are also very noisy compared to the BATs. Save some money and look at the VTL 750 Reference monos. Much quiter and all the headroom you could ever need.
Thanks Jtinn, for your advice. About a year ago, I had an opportunity to acquire a mint pair of VTL Wotan but I wasn't ready to, just acquiring the BATs. I understand the drawbacks of Ref60os but how about the sound? How do they compare to VTL or BAT soundwise? Would appreciate your sharing of experience.

I think the new BAT equipment is superior to the Ref 600s in every way execpt soundstage and ultimate power. The REF 600 MKI & MKII are very thin sounding, tonally inaccurate, hotter than a radiator with bloated bass as well as a huge noisefloor. They are also incredibly expensive in terms of tube replacement (short life tubes as well). They throw one of the biggest soundstages I have ever heard, and have an iron grip on notes. But, all in all I did not think it was worth ever owning them. The BATS, on the other hand, are dead quiet (comprable to ML & Krell in that respect), with exceptional tonality, detailed bass, beautiful mids and highs and great detail.

The VTLs are very good but you have to get the new ones with the latest revisions. If you get the newest VTL 750 Reference amps, they should do fine. The problem is that you are still dealing with a short life 6550c that costs quite a bit to replace.

If you want something speacial, go to the VK-75SE's or VK-150SE's. They are a huge difference over your current VK-60.

Let me know if I can be of any other help.

Good luck!
