Impex Records

I have three Impex pressings. Two are of Jascha Heifetz and one is of Frank Sinatra. They're all mono and sound very good to me. The Heifetz Beethoven Sonatas can sound slightly bright in spots but that could be my cartridge also. So whether they're all consistent, probably not. I compared the Beethoven Heifetz to the original RCA mono and believe the Impex remaster to be considerably better. It was apparent that RCA used filtering that was omitted in the Impex process. I also have vinyl from Analogphonic and Speakers Corner and find them all to be pretty similar.

I have some & they are excellent.

Right up there with UHQRs

I own a few, SQ was never an issue. It was always a pressing issue.

Impex has been all over the interwebs for the last few weeks.  They seem to spend a lot of time making a finished product.  

I agree with the above.  Well worth trying.  Have similar issues with the Barber disc, but overall sound is killer.
