Recommendation Tube Integrated

Don’t forget to consider Atmasphere. 

I would think carefully before changing from SS to tubes for the Harbeth 40.2's.

I recently bought the 40.3's and even with gobs of power my Rogers High Fidelity EHF-200 did not sound good with the big Harbeth's. 

It's not about power it's about damping factor/impedance matching.

I switched to a BAT VK3500 (hybrid tube/SS) and they sound amazing, but  this was an expensive lesson for me.

Quicksilver amps are Anything but "creamy"......very harsh.  Decware is good if you can find one.The Harbeths need power. I wouldn't go with anything tuby unless it's a MAC Hybrid w/ 150 watts min.

@macg19 I couldn't agree more. I have a Cary SLI80 HS paired with Volti Razz and I am over the moon with the set up. In my opinion I'd need to go the route of pre-amp and monoblocks to significantly improve where I am now. There's just good musical synergy with my current set up. 

I'd normally highly recommend the Cary most of the time. However I feel the Cary SLI 80 would not be a good match with the Harbeth's. Perhaps the Cary SLI100, on sale now at Cary Direct starting at $3897.00. More if you fully option the unit, which I did, and do not regret in the least.  

+ 1 for Rogers.  I have an EHF 200 Mk 2. It’s amazingly powerful for a tube integrated, all class A operation, so it runs hot and is not easy on output tubes.   I believe that its quality of workmanship is unsurpassed.
