Thanks Jakeman - I'm sold on the 60's.

The tube amp won't clip in the same manner as a solid state amp. I wouldn't be concerned about damaging the speakers with the tube amp.
However, you'll be drawing excessive plate current if your amp is not rated for 4Ohm speakers and you'll be replacing tubes frequently.
Hey good point Mojo.  There is a big audible difference between the hard clipping of a solid state amp and the soft clipping of a tube amp. In both cases you are running out of headroom. In the case of the SS amp you fall of the square waveforms very quickly and the noise is very annoying. With a tube amp the soft clipping and longer roll off the round waveform can actually sound pleasant depending on how many second order harmonic components are generated. Though even with tubes the sound gets more distorted quickly as the volume goes up.
25W doesn't leave much headroom with the 80s but it may work with the 60s depending on the quality of his tubes and the circuit design. You'll know when your tubes start to degrade by that dull film like sound and the tubbier than usual bass. I have had several tube preamps and amps and tube rolling can be addictive, not to mention expensive and occasionally inconvienient. These days after much experimentation, I run a tube preamp and a SS amp in my 2 channel system which gives me the best of both.
Good choice Tamzarian.

1. Although this reply is to to Jakeman, thanks to all for the invaluable information provided on this thread. I think my wife is going to enjoy the 60's.
2. In the event that the Soundstage One Hybrid ($395 CAD) doesn't quite cut it, any suggestions as to the "next step up" hybrid tube amp, which doesn't cost me my 1st born child (I'm always prepared to surprise my wife if things don't quite work out right).

Sorry, I left out a lot of detail - I'm only looking at integrated tube amps, and they don't have to be strictly hybrids.

I'm not as familiar with integrated tube amps. I'm more into separates so I can't help you with that one.

Jakeman: If you have a suggestion for a "cheap" preamp/amp pair (< $800 for the pair), I'm all ears.

I can't think of any in that price range that would do justice to the 60s. Best to try out that integrated amp first. I know there is alot of great gear coming out of China now at very low price points so please post your impressions.

I'm with you John, you start getting that cheap and you may be sacrificing quality. Emotiva makes a few combinations that are close to that price range and would do great with 60's.
