Default Gainclone vs tube

both the gainclone and most tube amps can be very simple designs and deliver performance that belies their cost but how would they compare to each other.

Say a good gainclone like the gain card (25W) v/s an EL34 PP Triode or UL (15-30W) ?

BTW I did read the thread comparing the gainclone to Leach etc..but that was a SS only comparision and I did not see the AKSA mentioned.

I'm not sure what "most tube amps" involves, but my experience is that they take considerably more money and skill than a GC. Mind you, I prefer a good DHT SET and think it sounds better, but it is not going to get built for $100 like a GC.

I had the chance to compare a GC with a 3 stage DIY PP 20W classA triode, both made by me. The tubed amp kills the GC in every department. But the GC is way too good for the time and effort. Its certainly cool and fast sounding. For those that havent experienced the GC, I can say that it reminds a lot low powered Naim Audio models for tonality and pace.

Excellent review. SO any other tube-chip combos out there?

I use tube pre (Bottlehead foreplay) with IGC power amp.

Suits me.

Almost everything I've read about gainclones says, you want a right-sized power supply that can supply current at a moment's notice. Battery PS has been recommended, as has hi-cap Carlos AC PS. Regulated PS gets mixed reviews, personally I think regulation just gets in the way of supplying current to the IC. To me, a well-implemented GC is inherently low-noise, regulated PS doesn't appeal, but that isn't dogmatic.

The catch with tubes is that they require good iron. That's the thing that has struck me, again and again, while looking into these things. And good iron = $$$.
