Thanks for your suggestions/recommendations. I have to add that the room size is approximately 3.00m x 6.00m, I listened mostly to blues, some rock, pop, jazz and sparingly classical (Mozart). Also, if I ever did buy a tube integrated amp, I also plan to use my Mordaunt-Short MS 20i Pearl speakers (sensitivity 89db, 8 ohms) as an alternate. The MS is currently located at our living room (approx. 4.00m x 4.00m).
I read that single-ended amps sound better than push pull but the former have less powerful output. I'm leaning towards a push pull 50w or 75w but the thought that single ended sounds better is giving me second thoughts.
Can you please make additional recommendations? Thanks a lot.
