I had a Yamaha A-S3000 four amps ago. It was the silver face model. IMO that amp was the most beautiful solid state integrated amp out there. It sounded great with my Infinity RS4b speakers.
It wasn't a good match for the speakers I upgraded to after the RS4b's so I sold it. I have a 2nd rig now that uses the RS4b's and that's where I miss the A-S3000.
Any regrets in selling gear?
By its nature, our hobby/passion for gear encourages buying and selling gear, hoping to land on a final purchase, that point of satisfaction where you can sit back and just enjoy the music without any niggling issues about there mechanics of it all.
That said, is there any gear that you came to regret selling?
