Audio Research 75 SE

Rrolack ... I just dropped 2 quads of KT-150s into my Ref 150. Sound is better, but not transformational. So I wait to hear back from Oregonpapa and Carey1110.

I actually found the KT-150s to be a huge step up in the Ref 75, particularly in the bottom end. Best money I ever spend in audio.

That said, I'm also super curious to hear how the upgrades change things.

Hmmmm, well Obfiscation Central were hardly going to leak any other set of percentages were they? when one does the math on the residual $3000 for a handfull of resistors and capacitors, together with a meter or so of silver plated copper wire!!! Or are we being taken full circle back to ' costly proprietary Teflon ' Capacitor Gate once again?

Those ARC technicians must charge more per hour than my Wife's Orthodontist and Gynaecologist put together!

Well, all I can say to you, Tsushimal ... is that ARC, like all businesses, has expensed to meet. Your post reminded me of the old joke where a brain surgeon had to call in a plumber to fix a major leak in his home. When the plumber presented the bill to the brain surgeon, the surgeon looked at the bill, then looked totally shocked at the plumber and said: "Hey pal, I'm a brain surgeon ... and I don't make this kind of money." The plumber looked the surgeon n the eye and said ... "Neither did I when I was a brain surgeon."
