Music First Audio Passive Magnetic Preamplifiers?


I want to know if anybody tried and compared this rare preamplifiers.
I´m really interest on this brand but I couldn't find anything here in Audiogon.
I will apreciate your opinions.
Thanks

Oh yeah, my classic does NOT have the mk II transformers. I'm sending it back to MFA for the upgraded xformers and the remote option. Im also having a custom bypass switch installed so I can do comparisons more easily between different digital volume controls i.e. Pure music, Audiophileo....etc.
The MFA is said to sound very much like the BENT Audio passive when it used the S&B transformers, I thought the Slagle autoformer version - the BENT TAP-X - sounded even better if you can believe it, and better yet the Lightspeed Attenuator. Given the equipment you have been listening too, I know you could easily try the LSA - not full featured or anything, but for sound? I've not heard a better passive.
I built a passive for my bench testing of audio equipment Ive built (amplifiers and such) using shallco and roderstein mkII resistors. I had a buddy visit my uncle who was using my passive and he commented that it sounded exactly like the LSA. He owns the LSA but I have never heard the LSA with my own ears so i can't second his opinion. I can say that I would rather listen to my classic or Ref MFA units than the resistive passive I built :)

Honestly I'm not knocking the LSA but i probably will not go out of my way to audition it either. I love the fact that the MFA units will inherently convert a S.E. signal to a balanced signal as well.

Perhaps my uncles buddy will bring his LSA by one day in which case illl haul the classic over :)
Yes, I think that the type of quality one can approach with the classic at ~3k is astounding with the copy classic...I'm not a fan of silver wiring so much :) though I have heard some silver sound quite good.

I'm sure the Bent Audio gear is extremely good as well but I have not been privy to it. I also once had the Bat Rex, absolutely no contest for the classic.
