My amp has no faults

Oh, well if you are looking for amps for an active system that does change things. No pesky amp-crossover interactions to worry about. Fun stuff.

I will be using the Acoustats to start with but I for one like merry-go-rounds.

On ESLs, OTLs are often described as 'the best'.

Tubes in general usually work better on horns and high efficiency speakers than transistors.

Some speakers are such low efficiency and/or impedance that you need an amp with a lot of power and is comfortable with low impedances. In such a case transistors will likely serve better (despite the misgivings I have about transistors).

If you read the article at that link then you know more than most about the matching issues involved.

For me convincing is more a product of the speaker and the amplifier than just the amp.

That said:
My NuForce and now nCores have, to a large part, spoiled me for most linear solid state amplifiers. Of course there are new solid state amplifiers that I could never afford that I'm sure could hit most of the marks the switching amps do.

There is one area most linear sold state amps fall short compared to my switching amps. In driving my Eidolons they begin to get congested and distinctly fatiguing at higher listening levels. For me this is a big issue. The ability to listen to music comfortably at more realistic levels is THE luxury of high end.

Neither the linear solid state or switching amplifiers do second order harmonics like tubes which is why my nCores are relegated to the studio. I have finally found a pair of affordable 200 watt pentodes that can drive my speakers effortlessly.

Even though tubes may have the most amplification faults, those faults are an easy trade off for the characteristics I value in entertainment playback as opposed to the desired clinical playback the switching amplifiers provide in my studio.

Technical evolution will continue, for now its about the right tool for the job.

Thank you, Ralph. I did read that paper when it was recently referred to on another thread and just read it again. I'll probably read it a couple more times yet. Seems like it could be a game changer. Possibly in a mix. I like the bottom end to cut like a knife.
