@audiosaurusrex Thanks for the info! The Q3 (their new larger model is rated at 90db/4ohm and has a minimum suggested power requirement of 20wpc, so it would probably be pushing my luck with a 2a3 set at 3.5wpc haha!
I'm hoping they bring them back next year for the next SWAF show and plan on spending a fair amount of time in their room next time to really hear how they handle different music types and whether any fatigue develops.
Enjoy yours! The Octave is a great amp & I see you also have the MW PH9.0X. I just got the 'T' upgrade for the power supply and it's been great, if you ever consider upgrading it a bit.
