Hey John I just wanted to say a heartfelt thank you for all your advice.My Acoustats are singing and all is well in the world.Regards from Barbados derockster 
Did you get the ADC...which one did he have in stock still - the
ADC XLM II's?
I gotta' visit Sounds Unique one day...he's only an hour south of me.
Mike was charging like $79 or something a year+ ago for them...did he raise his price on them? For anything near that price, I don't know anything on the market that can compare to them today.
The AT440ML/OCC that I have (now morphed into the AT440MLa and costing from $99 to $129) is good in a lot of respects, but it's tilted to the bright end of the scale (yech). Someone recently told me to load mine at 33K and it'll change it's demeanor
drastically. So, I may give it another go after burying the last time it was squakin' in my ears

Nonetheless, for $80 or so and no fuss setup at all....the ADC is king at that price point today (Grado's are wonderful creations, but terribly frustrating to get them fully optimized). The extra voltage of the ADC should give your system a bit more oomph, too.
Regards!! John
