At the moment I am using my Beresford Caiman as a pre amp into an EL34 power amp & since upgrading my speakers to a pair of Tannoy Eatons the sound has improved greatly.

My question is would I see another improvement in sound quality by using a dedicated pre amp? Connections wise all my sources are digital (Squeezebox, DVD) and hopefully sometime in the future a SACD player. No real space for a vinyl setup so no need for a phono section.

Budget wise I like to buy 2nd hand so I was looking up to £350 and was considering something like a Croft Micro.

Any advice would be greatful received.
