Ah! So the enclosure you have to work with is the plinth. Ya know... Something like the Connex SMPS300RE (or my SMPS-86) would fit nicely.

Chris: Thanks, they are a 'long term' project. Eventually will dipole the bass, but for now they do the job, even if in a 'difficult' room.

Tom: Have the transformers (12 months now ) but will be using SMPS on my next project for the kitchen. There I have the box already (Denon POA-F100 I bought for a surround experiment that never happened). I have more space in there esp as will be lower power.

Will all be worth the wait...

Sadly not my rig. My listening room is embarassing. But the speakers are the same.

I finished another stereo mod86p for a friend today. Sounds awesome as expected. I really should box my own unit up...

I've been saying that for 2 years... But it sounds so great why would I mess that up with a box when a MDF board works so well?

206 W into 8 Ω @ 0.0006 % THD+N verified. 350 W (4 Ω) when my lab supply hits its current limit. I expect the actual limit to be closer to 400 W.

6 x LM3886 + LME49724 + OPA1642 in a Bridge/Parallel Differential Composite Amp architecture.

Availability: Preorders by end of January 2018. Full production towards mid/late February.

Just saying...

Tom

Kaboom! Nice! Hope you sell a gazillion! A nice option for those who don’t want to go Class D and get better documented measurements to boot!

Best,
Anand.
