Looking for a good Integrated Amp for my Nola Boxers

price would be no more than $1200 new or used.  I have a Aaron "5555" Anniversary integrated (50w) from the late 90's that I purchased from a fellow Audiogoner years ago.  It sounds good but I'm looking for something thats a little more resolving and transparent.  a little more power would be nice also. would like to stay with ss. thanks for any insight!
I'm using a Simaudio I-5 with a pair of Boxers and really like the combination. Mine is the LE version but I've also owned the standard version and it's a beautiful sounding, exceptionally well-built amp with excellent ergonomics. There's one available in the classifieds listings here now, not mine, and within your budget.
