Hanshhh,
I have gone thru somewhat the same experience as you. I owned a very high quality 300b amp and just totally enjoyed the listening experience even though my speakers were not really designed for a low powered SET amp. Being the typical audiophile I sold the 300b and bought a great 70 watt k88 tube amp looking for better sound. I enjoyed that set up for about a year and when on to a different speaker. 6 years later I have gone back to a 8 watt 300b amp and I could not be more happy. If you are drawn into the SET sound like I am then you must get a SET friendly speaker. You will never know how good a SET amp sounds unless you get a speaker designed for a SET amp. I now have a SET friendly speaker (96db) and the music to my ears is the best I have ever owned. So my suggestion is to buy a SET amp and see how it works on your current speakers, then down the road purhase a pair of speakers that really shine with SET amps.
