MW Sony HAP-Z1ES

My MW Sony HAPZ1-ES arrived Thurs. After 48 hours of break-in, I'm at the point where I can enjoy it. Sound stage is expanding in all directions, images are well defined with solid density, dynamics improving with excellent Bass and High extensions. Still hearing POSITIVE changes so can't wait until it's fully broken in.

Setting up the Sony was SIMPLE. It took me longer to replace the fuse than launch the program and download music to the unit.

The stock fuse was replaced with SR Red immediately. Replaced stock tubes after 24 hours with NOS TS 5U4GB and 60's Siemens e88cc.

Comparing to MW 6SN7, one is not superior but just different. HAP-Z1ES has superior detail, resolution, more neutral and less warm but definitely not bright or SS sounding. Personally I prefer the sound of the HAP-Z1ES. For reference, Shuguang BT cv181-z was my favorite 6SN7 in MW.

FYI, I was also considering Bryston BDP-2 or Antipode with Allnic D5000 ... Dac. Ultimately chose Sony due to simplicity with available reference mods and definitely not disappointed in my decision.

So far the only suggestion I have is it was difficult removing the driver tubes from the unit. I couldn't get a good grip so either increase tube exposure or expand the hole diameter.

Dan clearly hit a HOME RUN with this new transformer coupling design. I look forward to new MW models with this design.

Thanks Dan for the excellent work and service.
