Great question! Also interested. I'm another fan of the Belles 150A Hot Rod. It's really a great sounding amp. Always wondered how the 150A Reference sounds?....
Belles reference 150A Vs Belles Reference 150A V2
Has anyone compared the Belles Reference 150A against the newer Belles Reference 150a Version 2. The orignail 150A Reference has a 1000VA transformer and the newer V2 has a 650VA. The Bass should has some effect of the smaller transformer? I own a Hotrod 150a and wanted to upgrade to a used amp for 1,400.00 I own the Belles 21A with the Aurua cap upgrade already. I love the belles Hotrod sound but want to have more resolution.
