Solid State for Rock and Tubes for Jazz, Yes or No

I use a tube amp with a MOSFET REL sub...thus I am conflicted as to what camp I'm in. Where am I, and who are these people? I'm frightened.

Not to say it cannot be done, but I have yet to hear a SET amp do rock/pop well, at least on the usual terms of rock/pop music which is different than much classical, jazz.

At shows, when SETs and high efficiency horns have been featured, the demos are always jazz or classical.

At Capital Audio fest, after hearing some nice sounding Jazz being played, I asked to hear some Rush on vinyl in the Zu room where their larger high efficiency speakers were being demoed on a 5-6 watt tube amp. It sounded nice enough in a polite sort of way, but much lacking on any kind of muscle or drive needed for that kind of music. The ZU guy admitted more power was needed really for that.

So I am thinking it may be possible, but certainly much more of a challenge than other approaches perhaps. I just have not heard it yet, though I am sure I have not "heard it all" yet regarding SETS/hi eff. speakers.

THough no rock music was played, I felt like the Atmasphere/Classic Audio combo at teh same show could have done it nicely, but that was a much more powerful tube amp being used, not a SET.

Both my SET and my pushpull amps can be considered marginal, in terms of power, for my speakers. My SET amp is rated at something like 6.5 watts and the pushpull is 5 watts. I don't have any problems playing rock at fairly high volume.

Where some power issues do show up is with large-scale choral music. I do notice some compression and mild clipping if I try to play something like Rachmaninov's "Vespers" at somewhat high volume.

Good SET systems do reproduce classical and jazz music convincingly.The irony is that recordings of these two genres are often done to a higher quaility standard than a lot of rock and in most cases also provide a much wider dynamic range gradient with better musical ebb and flow.Much of rock and pop music is by comparison compressed so it seems listeners will compensate by cranking up the volume.Absolute volume levels will be in the domain of higher power amps if that`s the goal.

I`ve heard SET play digital and analogue rock recorgings very well in terms of overall sound quality and involvement,it was loud but not 'crazy' loud.

What I have seen/heard to date with sets is consistent with your assessment and I would tend to agree.

Rock music is meant to be played/heard loud but some may not care for that so it is not an issue then.

Of course peaks on orchestral and even big band jazz recordings for example can get pretty loud, but from what I have heard, SET power may not be as big an issue there for most.

I have heard some orchestral recordings with convincing dynamics on at least one very high efficiency horn system using what I recall to be fairly low powered (but very expensive) Audio Note tube amps (not sure if these were SET or not though).
