Preamp: Mcintosh vs Modwright?


I asked this on the Bryston board over at Audio Circle and was hoping that some of you Agoners may provide some help.

I am looking for a tube pre to go with my 14b (speakers are OB1's) and am looking at either a
Modwright SWL 9.0SE or a Mcintosh C220.
This would be moving my Musical Fidelity CD-Pre24 to handle just cd playback and no preamp duties.

Feature wise, the Mac is more than I will use (no turntable in my system), where as the Mod, being
only a linestage will probably be enough to handle any future components.

Has anyone had the chance to compare these two pre's with a Bryston amp?

If I go for the Modwright, I would get it with the SWL Tube Recificatication Upgrade.
Cost wise, this would make about $3000 for a new SWL vs $3300 for a new C220.
I realize on the used market (Agon), the Mac may command a slightly higher resale price than the Mod.

Any opinions would be greatly appreciated.

Being what is basically a prototype power supply makes me wonder how much Dan improved upon it before he was satisfied enough to offer this as a production model.
It's not like Dan never does any tweaking to get to where he is going.

I think the ad was a little misleading, although I don't think the seller did so on purpose.

I just heard from the seller and he has excepted an offer so it looks like I will be moving on.
The search goes on.
I don't know exactly what changed from the first run of 50 to the next production. I know there was a muting circuit change, and a layout change probably to ease the assembly. Aside from that, I don't know of any differences that would affect the sound until the introduction of the new caps recently. Dan would know of course.
These were not the prototypes, though. The prototypes were the 2 box beta models. There is one here which you've no doubt seen.
