I have both a NAD 7175PE receiver and a C320BEE integrated. As was stated by Ferrari the amp section of the 7080 is the same as your 3080. My 7175PE is the generation after the 7080. Though it has more power than the C320BEE (75 watts compared with 50 watts) the C320BEE is noticeably more musical. I am using it with a pair of Dynaudio Audience 42 speakers in my bedroom and it drives them with ease. One other thing to consider is the age of the 7080. I have had to have some solder joints repaired a couple of times in my 7175PE.
Vintage NAD 3080
Hard to find much information about this vintage NAP integrated. Thinking of using this to drive a pair of newly acquired Von Schweikert VR-1's. Anybody have any thoughts on how this system may work, given that I'm using them in a small bedroom in a nearfield setup? The VR-1 as I am hearing them are somewhat lean and bright, so I would like an integrated that would smooth that out some. I can pick up the NAD 3080 for $219 at a local hi-fi retailer, which seems like a reasonable price, but I am just wary of using such an old amp. For a budget of $500, would you guys just recommend that I forgo the 3080 and invest it in a used NAD 320CBEE or perhaps even a Jolida hybrid integrated?
