ModWright Tube Buffer


Does anyone have any experience with the ModWright Analog Bridge Tube Buffer? I'm thinking about adding it between my Musician Pegasus R2R dac and a Yamaha A-S1200, but am a little put off by the price (~ $3,000 used) considering it's nearly as much as the Yamaha.

I'm generally satisfied with the Yamaha/Pegasus combination, but miss the tube flavor that used to power my Klipsch Cornwall IVs. I've contemplated returning to a full tube amp, but I really don't want to deal with the revolving door of tube replacement (I put a lot of hours per week on my system). 

Thanks for your thoughts.

Tube buffers were popular 25/30 years ago. The Mod Wright seems overpriced but I'm clueless on what's inside.

Musical Fidelity made one years back, it was cheap, sounded good, and at the price, made sense.
But I don't really think $3K used makes a lot of sense, or maybe I'm missing the application or target end-user?

I would sell my SS preamp, add the $3k plus the cost of a PC and IC's (another $1K), then buy a good tube preamp. 

dan’s unit is no doubt well built but as mentioned above it is quite pricey and maybe overkill for what it does sonically

steve deckert's z-stage (decware) is a functionally equivalent unit for much lower cost and complexity

not cheap, but a lot cheaper than the modwright unit

These tube buffer units intrigue me  I have a very nice SS preamp and am probably silly to even consider it.  But, if  were to try one, just to play with tube warmth etc, I would want a switch to bypass the tube unit completely.  Does the ModWright do this?  the Decware z-stage does not seem to.
