That's why Spendor still also makes the Classic line.
But good luck finding the 1/2 or the 100 to audition.
The conversation has certainly taken a tangent or two! So in an attempt to redirect, it would seem most people (who have responded) seem to prefer tube amps to solid state.
I wanted to focus on solid state options albeit tubes are very interesting and as I understand it typically provide a warmer sound which was my stated intent...however I hoped there may be some solid state options worth noting.
You are right Gearhead, sorry.
On your budget an amazing solid state amp value is a used (only way to get one) McCormack DNA.5 that has been upgraded by Steve McCormack. They are ridiculously good for the money is stock form at full list price but to get a used one that has been modded for the $800-$900 prices they seem to go for is an even better deal. I make this recco because I own both a DNA.5 and DNA-1, both modded heavily by Steve. The .5 sounds sweeter but the 1 has more bass ooomph and propulsive-ness. They both "like" a tubed preamp as they have a suitable input impedance. This will sweeten up the tone too and tubed preamps are far less prone to problems than amps (unless you get an Audible Illusions 3A so my advice is don't).
But I will say it again. Your question is just too broad and generally unanswerable. You are going to have to try stuff. Buy used so you can re-sell on this forum if you don't like it and limit your losses.
