I Have used ss pre and power for years and years and....recently decided to give tubes a try.
Was using a krell pre and krell 2250 power amp plenty of current to drive my tannoy D700s
So got the chance of an Audio Research Ref3 pre (new tubes) and all I can say is should have done it years and years and .....you get the drift.
The Krell combo was dynamic and detailed but the Ref3 has transformed my whole listening experience to another level; more live sounding, engaging, without loosing any dynamics or detail....wonderful !!
