Anyone have a Music First Preamp ?

If you can afford the Music First, you can afford to try the <$500 Lightspeed Attenuator - might be interesting if you want to be amazed. When you don't have impedance issues to worry about, it clearly bettered the TVC (S&B) passives I have owned. The low price makes all the more amazing - though it surely cannot compete with the quality of the chassis of MF gear - top notch.

100% agree with Pubul57. My friends have the copper and silver versions. They sound very nice, but waaaayyyyyyy overpriced IMO. You should've saved some dough and got the Lightspeed. I hope you bought your MFA used...

Not that you want to get paranoid about this stuff, the MF is, I am sure wonderful TVC, though I doubt it is any better than the BENT version in TVC or AVC formats, they were and they remain SOTA passives, but if you have <200 ohm sources and 100 kohm input impedance amps, I can guarantee you that the Lightspeed will be a worthwhile listen, and at a much lower price point -- for now.

Anyone compare the MF or Lightspeed to a StereoKnight silver passive?
I've only heard a StereoKnight and was highly impressed.

I've had both Lightspeed and MF in my residence recently.

The Lightspeed is only better than the Music First when the input Z of the amplifier is significantly north of 50K ohms, at least 100K ohms to be conservative. Given finicky system matching requirements, I would not say that the Lightspeed is better than the MF, but I would say "Well, it depends".

Having said that, in the right system, I do prefer the Lightspeed. I prefer the B1 to the MF as well, but the dual channel volume control on the B1 drives me nuts.
