Anyone have a Music First Preamp ?

Guys found my m music first pre to be quite resolving and for my price am pleased with it so far.Bought it new for around half retail so good price performance for me.So where does one get the light speed from.

Al the contact and pricing information can be found here:

Google it. You will likely get the LONG DIY thread on all things LSA. You need to buy direct from George in Australia. Should be <$500 with a Walwart to power the LEDs.

>significantly north of 50K ohms, at least 100K ohms to be conservative

really? rut-roh

I suspect 50kohms would work fine, now if you are looking at 10-20kohm you might be pushing it, though some listeners claim it can also work for them. George from LSA does specify >50kohm - tubes in other words (for the most part. But, that's why Nelson Pass built the B1 - has to drive his SS amps:)
