Interesting in that I was not going to join this thread until it became evident that the room size and speaker efficiency of Baroque_lover's set-up is very close to mine. I have been using a 50 watt triode push-pull amp with my 88db speakers for some time now with very good results. I have also been pretty biased to tube systems for some time and agree with those who recommmend tubes based on the type of music Baroque_lover enjoys. However, in looking for a new amp I have listened to some flea powered SETs, as well as higher powered push-pull designs. I have to say that I do not believe a SET amp is a good choice here based on the speaker efficiency rating, unless you can get one upwards of 45 watts or so, and that could be difficult and/or expensive. The higher powered push-pull designs I believe would work well and there are many choices at different price points.
As for me. I'm going to give a solid state amp a try with my Spendor 1/2e speakers and compare it to my triode. I anticipate that there will be differences in sound but since I will be keeping tubes at the preamp and phono stage levels, I may succeed in maintaining warmth while tightening up the low end and driving my speakers to take full advantage of their dynamics. Only way to find out is to listen.
