Hi John
Twas Rega Isis CD, Belles Pre and Power Monos.
I'd heard the TAD kit before but couldn't justify the price for the uplift in sound quality
All change when a Coherent Grounding Box came along and everything sounded better.
The difference to TAD was now significant. Enough for me to splurge. Glad to say 2nd hand and not list !
Sound was good before. Sublime now
