Is Nelson's pre as good as his amp ?


Just wonder is it worth to replace my arc ls-3 with aleph p ? This wonder is based on very satisfied experience with aleph amp (first 5 then 2). OTOH, one stereophile's reviewer seemed to prefer AI M-3. Any thought ?

the aleph-p is one of the best pre's in the world.....i have compared it to almost everything that s out there.......new & old....still one of the best active pre available........its up the ai m-3......again a lot depends on your amps and there sensativity ratings and all that great stuff.....
The Aleph amps prefer a balanced input signal. The Aleph P is a great preamp that mates well with the amp series.

What? These are the original single-ended solid state designs. As I recall, the Aleph 3 doesn't even accept a balanced input.
