Any McIntosh C48 owners out there?

Well, I actually was lucky enough to find a used C48, and my observations are very similar to Mglenn's. But the biggest thing I noticed was that the sound was very clean and very spacious as compared to my former C37, which has the same specs as the C48. All-in-all, it's a terrific looking and sounding preamp. The volume control is very quiet and smooth, which was a big concern of mine, as I worried it might be like the C42's. It's not. It also has the 5-band equalizer, as compared to the 8-band Mac seems to like now, and even it's new stablemate, the C50, is using the 8-bander. The phone jacks have gone back to 1/4", vs 1/8" Mac's been using for awhile.
I can see me keeping this baby for a long time, heartily recommended.

I have owned a c48 for about 6 weeks now. I'm a bit frustrated with the DAC performance. Its very harsh when compared to my wyred4sound DAC2. Chuck Hinton at mcintosh said the soon to be released drivers for the usb will change how it sounds. Im skeptical since I was listening to 16/44 and even tried the digital coax in and still the harshness. It may very well be a great preamp, but its got two very serious flaws:

1. The only way to activate the HT Bypass is through a 12v trigger in. My wyred4sound DAC2 has that method in addition to a very simple "HT" button that puts it in bypass.

2. The DAC is disapointingly harsh and cloudy sounding.

I've been running the unit constantly since it arrived in hopes that its a break-in issue, but as of 6 weeks out nada, zip, no difference. I guess the wyred4sound unit is just that good, but something tells me it gets better (which is why I bought c48 to begin with).

Allen,
Could you please update us about how the DAC has been performing since your last post? I am waiting for my C48 and have the W4S DAC2 and Bryston DAC and was hoping to sell one or both if the MAC's performance is identical.
Thanks.
Richard

I don't believe Mac has released drivers for it yet.

Question. Where does the C-45 fit in with these Mac preamps? That is, if it fits in at all.
