Thanks folks for the input, which kind of solidified the way I was leaning (toward the Pass). Surprisingly was able to get a new one for around $7500. I wanted the tube/SS combo deal on the Mac as that was my initial consideration, plus the balance control that I finally realized I didn't need (I had another equipment problem I fixed). Input from you and others convinced me I could get the warmth out of the INT-60, and the backlog and lack of info on the Mac started to bother me, along with some uncertainties some have had about their service facilities and support, not to mention the ownership change. Probably not to worry, but no problems there for sure with Pass, although was surprised no dealer in Houston area (or Texas).. One other thing you may have an opinion about: heat management. My rack has a space just big enough for the amp but is completely open front and back. I could put it on top but am concerned that might be getting top-heavy up there. I'm putting a maple platform under it as its feet are an inch or so farther apart than my 15 inch support. Upgrading has put me into a league that I have to have my son lug the equipment for me! Times change! Thanks for the help.
Mac MA 352 vs Pass INT-60
I've had an order in for the Mac MA 352 for 3 months and supposedly it's coming shortly. I wanted the tube front end but now I've got an option since I no longer think I need a balance control and I just found a really good deal for a new Pass INT-60. I'm running these, hopefully, into KEF R7 Metas at 88 dB. I figure the Pass is adequate into those 4 ohm speakers in my 25x14 space. I also figure the Pass has as much tube-like quality with likely a better high end than the Mac. If price is not a factor, what do you think? The Pass is a beast, but I can deal with that, and my first real amp was a Threshold 400A. I have some worry about current delays in Mac serviceability also. :)
