Best Integrated for 400 dollars

Used Rega Brio is quite musical, new NAD 3020 version (50wpc).

I'm using an 80's Sony "Legato" "ACT"(Ta-Ax6) int. amp to drive my Chorus 705's. It's an excellent amp. Another 80's Sony int. amp (Ta-Ax44)drives my daughter's Energy XL-15's. For the $ used, unbeatable. IMO, I would look into a warm sounding/refined int. amp to drive JM Lab spks. I would consider a Marantz PM-57 int. amp as well. A soft/mellow sounding int. amp which would mate well to the JM Labs. (I have mint one w/box, manual & remote. Send me an e-mail if you'd be interested.) Also, you'd might consider older (70's) Kenwood/Sansui int. amps as well. If I had to choose an int. amp on your list, I'd go w/the Arcam. (I know a dealer which has a very hard to find mint Arcam 5+ int. amp.) Good Luck. Bill

I found a Myryad MI-120 on this site for $450. Incredible build, features and sound quality.
