Tube Watts Vs. Soild-State Watts?

I am considering replacing a large solid-state amplifier with a decent sized tube amp, and was wondering what I may be giving up/gaining by making the change? My speakers are quite sensitive, about 98dB. I love the dynamics and bass control the big SS amp provides, but I would like to get more resolution and detail out of my music. I don't play music at loud volumes, but I do enjoy decent listening levels. Any info appreciated.

Hi 333jeffery, 
What output tube does this amplifier use and is this a parallel SET topology? 80 watts is a lot for a SET.

Jeffery,
Your description reminds me of a NAT audio (Serbia) type SET amplifier. If at all similar then it will have terrific quality output transformers and very robust power supply. They are very ruggedly built.

NAT Audio uses a Phillips QB 5/1750 tetrode to generate 80 watts from a single tube.

I believe the chances are very good that you'll have success with this NAT amplifier matched with your Tekton DI speakers. Let us know your listening impressions when you have the time.. Congratulations.

I'm with Al  in regard to the output tube selection process, confirm with NAT  before even thinking about any possible tube alternatives.  This is a serious amplifier with ultra high voltage and I'm certain strict design criteria and circuit and power supply layout. Reviews and word of mouth say this is a superb sounding amplifier. I'd be surprised if it doesn't clearly outperform the Musical Fidelity transistor amplifier currently in use. Jeffery you may discover that you've achieved a world class audio system.
