This thread has had me scanning around for all sorts of heavier amps! Trace Elliot, SWR etc. I think I’m at the stage where I’ve tried various class D’s, TC RH450 &750, GB Shuttle 9.2,, TH500, GK MB Fusion, DG M900. The last two I still own, and the GK has served me really well, but I’ve got a hankering for something A/B. Was tempted to sell them both and go for a new ABM600, but I’m now leaning towards going for an older EBS head, HD350, TD650 or even a Fafner
