if you're liking your Cambridge, maybe just a step up the the Azur 851A Integrated might do it for you...I have one and it is quite good, more powerful and better sounding than the model you have...
Best sounding amp/preamp for Snell Type E/ll model speakers?
What is the best sounding amplifier/preamp or integrated choice to use with Snell type E floor standing speakers? They are efficient. Specs: 91db Sensitivity, 4-6 ohm Impedance. I hooked them up to a Cambridge Audio Azure integrated (65-70 watts per channel). They sing and sound lovely, that wonderful bass and sound the company was famous for but I and wonder if they could sound better with a different amp? Are they best with tubes? At some point I am going to pull the trigger on a Freya Plus or Quicksilver preamp but not anytime soon. Other associated equipment I can use now: Adcom 5400 amp, B&K Ref 200 amp, B&K Sonata Pro preamp, Apt Holman Preamp. Any suggestions would be appreciated.
