Tube amp advice

VTL or Manley?

I drive my JM Labs Focal Electra 936s with Amps that weigh 80 lbs a piece and are rated at 75- 78 WPC. The Focals are rated at a nominal 8 ohm impedence but have a 3.8 ohm min. impedence.
I agree with Raquel the output trannys must be big and heavy, to do the job right, the combined weight is about 160 lbs. They do a truly fantastic job and are very under rated, they are Opera Consonance Cyber 800 mono blocks. In fact they got a Blue Moon Award on 6 Moons, I encourage you to read the review. They List for $3995 new but you can usually get a deal on them. Used they sell for less than half that if you can find them.
E-mail me for a vendor who I know will give you a good price. No affiliation etc. But keep an open mind and ear these really punch way above their weight. (unitentional pun)

Manley Snapper can probably do it; and fully balanced.

Hi Dan,
That post by Raquel is absolutely correct regarding the importance of high quaility transformers and power supplies, they matter greatly. His suggestion of the VAC 70/70 amplifier is spot on, this was one great all time tube amp. It used 300b tubes in a push pull circoit and simply sounds wonderderful. keep in mind this is a directly heated triode tube(DHT) and not a pentode tube like the two amps you mentioned. The main downside to the VAC amp is the tube replacement cost for multiple good quaility 300bs(they do have a long life span however) but man oh man the sound! I do believe that the EAR 890 amp would drive your speakers very well, it does have very good transformers and power supply, just a different sound using the KT88 pentode rather than DHT tubes.

There is a Music Reference RM-200 on Audiogon right now which is known to drive difficult loads well. It's no CAT, and it's not 200 lbs, but 90 seems like a good start. I haven't heard the RM-200 myslf, but I do own its smaller cousin, the RM-10.
