Hi! I found your site a while back when I was researching DIY speakers. It's been a few years and I'm back to making something that will improve my listening experience. I'm interested in classical, classic jazz, and some new smooth/cool jazz (interesting differences between classical jazz and the more modern, highly electronic-augmented stuff!!)
I completed 2 of the projects discussed on the DIY audio site -- the Sony Vfet (P, 2021) amp and the ACP+ pre/headphone amp. They pair well and sound great to my ears. The weak part of my current system is the Polk Audio speakers that I "temporarily borrowed" from my home audio setup back in 2021 and have still not upgraded.
I'm looking forward to reding and learning and sharing on the Audiocircle site.
