The LCD-2.2 - yuk. No, just kidding - but it was not a favorite of mine at all. The EF-6 is not an amp you want to do long listening sessions with, you might feel like you just came from the dentist office getting a root canal.
Seriously: going to some audio store in Austin is going to be one of the best thing to do. Take along one of these: You might can get a fast turn around time at BTG, not sure what is work load is these days: http://www.btg-audio.com/ forget about Norne, it takes about a month or so to get your cable - However, he would have been my first choice.
You live in the states correct. OK well Reno Hi fi has one of the best in home trail and return polices around and Mark is a great guy to deal with - he will answer all your question. Oh by the way - he sell speaker amps For the price of the EF-6 Mark could hook you up with something way better. His stuff is mostly used, demos or refurbished but comes with a three year warranty. http://renohifi.com/FirstUsed/FirstUsedInStock.htm
Also there's AudioGon for a better verity, but I have not idea about returns there.
What kind of cable is that, I can't find one that looks like it exactly at BTG?
Is the above all that is needed to plug into a speaker amp? Is there anything else I need to be aware of when trying to run it off speaker amp?
