BIF,
Yes, Great advice.
In my post above, I meant to mention the Ref 75 SE as an amp choice. I don't feel I need the power of the Ref 150 (SE) class amps and 75 wpc will be enough for me.
I am going for the preamp first because I just purchased a Lampizator Big 7 balanced and a pair of Lampizator fully balanced 211 amps. An amazing combination but want to try a preamp in the chain. I am going direct now and can not believe what I am hearing. I normally prefer a preamp in my system but my current CJ GAT is not balanced.
I think an ARC preamp will, in this case, be a great choice. The only major difference I can see is the GSPre's out impedance is 500 ohms vs 600 for the Ref 5SE. Not sure if that means a whole lot, but I usually prefer the lower output impedance pre in my system.
