@vinpic Thanks for the update. Comparing it to the Ypsilon Phaeton says a lot!

Valvet’s AE4s are on my radar to explore / experience a higher watt and solid state pairing for the Nenuphars; and to serve as a ’book end’ in terms of differences from my 2A3 amps.

Looking forward to your updates as you run the E2SEs in.

@vinpic, 
Agree with David that favorable comparison to the Ypsiplon is high praise. Valvet amplifiers are  consistently well regarded.

@david_ten how did you install the rear brass bumpers on your Cubes? Did you have to install threaded inserts? Thanks

@abd1  I went with the unthreaded version of these:

I used commercial / industrial grade double sided adhesive discs.  I have not had any slippage.

The bottom rear cabinet area can be drilled, but it is tricky and there is a chance one may damage/crack the finish.

@david_ten So did you just wrap the adhesive discs around the hemisphere threads and insert? I have the hemispheres but haven't installed and still using the stock rubber bumpers. Where did you get the discs? Thanks.
