I'm listening to a pair of 1B's with a Cayin TA-30 right now , plenty of power and I'm very pleased with the sound of Vinyl and CD's. I would highly recommend a tube integrated as they didn't impress me when I heard them with a SS amp. That said they are not a speaker which you will get really heavy bass from as they don't go that low. You also might want to list your turntable setup as that may have something to do with it.
