I got it today. Before I even listen to it in stock form, first thing I did was change the power caps to larger 1200uF and changed the input caps to 4.7uF metallized polypropylene caps that I had at hand. I also constructed a simple battery wire with 3amp inline fuse.
This is not a "review"...just my opinion
The setup is Airport express --> Monarchy DIP --> Ack Dack 1.2e (battery powered) --> Modded X10V3 tube buffer --> Modded TA10 (battery powered) --> vintage Bose 201 with Cambridge SoundWorks passive subwoofer (I know..I need a better speaker)
The result is astounding! The words that come up to mind is holographic, alter black background, more space between notes, deep yet controlled bass, good treble extension, warm silky vocal range, just fabulous. Imagine if I had a decent speakers
I never been a fan of speaker systems but this can change things.
From memory, it's better than the standard T-amp and even better than Super T-amp. This is designed for DIYers in mind.
Next stop...putting it in a better case. The case that comes in is not bad, actually pretty good. But I need a matching "box" with rest of my silver box setup
