Always been interested in ZOTL amps, so the appearance of an Integrated gets my attention. But beware!! This is a VERY long review!
You think Srajan waffles? oh no...... but it's worth it. If the tax refund/Bond win comes in? Always been interested in timbre and subtlety in sound-hence my reccent 11 years with Ocellia full range (PHY driver) and now my Lavardin speakers.
Had a brief loan of a ZOTL about 5/6 years ago which didn't disappoint.

I have skim read that and it tells you nothing about the way ZOTL works.
It is NOT transformer less, the amplification is done at very high frequency, in fact classed as RF, using RF transformers, then converted back to audio frequencies.
A clever use of technology, as valve usually excel at RF, but IMO a complex hammer to crack a nut.
Quote of David Bernings design 'The high-voltage, low-current tube impedance-plane is re-mapped to the high-current speaker impedance-plane through a special transformer at a constant RF carrier frequency of 250 kHz (500 kHz for the ZH230)'
PS HOW MUCH? $7650, feck me..
