Nice amps you guys have. I have, or had some similar.
In the past I have had the entry level Prima-Luna, both stereo and the mono blocks. Also had First Watt Aleph J, F5, and original Aleph 3.
Today I have:
VTA ST-70 with the octal input tubes
Pass ACA mono blocks
Ayre Acoustics V-3
To try something different, I just purchased a Purifi Audio 1ET400A by VTV, with the Sparkos SS2590 input buffer. Looking forward to trying this amp. First class D for me.
Ah, interesting. So you're also a tube guy, and you're dipping your toes into Class D. Have fun! If the Purifi amp doesn't fully satisfy you, don't give up on Class D, check out the Cherry/Maraschino amps from DAC here on AC. I've heard them a few times at RMAF and they get tone right in a way that many Class D (and SS) amps don't.
