Am looking for an upgrade integrated amp for a smallish listening space (3.5 x 4 sq m). I listen to mostly vinyl and sometimes CD so I want an analogue rather than all bells and whistles that I'll never use amp. Based on reviews / comments rather than auditions, (not found any opportunity to audition as yet), my budget will go to either a used Norma Revo IPA-70b or a new Exposure 3510. Have any of you compared the two? How do they differ? Not bought used before so not sure what to watch out for but I have seen a couple of used Norma amps for sale online. A new Exposure amp presumably has the added bonus of a guarantee. As for speakers, as I have a small space I'm considering Larsens, Harbeths and ATC SCM 11 or 19s. Any suggestions / experience welcome. Thx
