Default Expensive box

That's one reason why i never got hooked by the marketing hype of naim equipment. As good as it is you just end up with a very expensive box ! There's better and cheaper equipment out there and they use Audio Mosfets....

I once met the late Julian ( Mr Naim himself ) at a hifi show in London around 1987 when i was in my late teen's. He was an inspiring person, had time for everone . Verygood at marketing as i remember....


Just my 2 cent's

Manytimes I had read here about damaging impact of capacitor in signal path. People say, that acceptable are only PP types. Now I see here on this position bipolar elyts. Naim is famous firm, with many fans. Something is wrong .

I've reached the same conclusion more than 20 years ago. Something is wrong with the fans' hearing ot they simply don't care about the finer aspects and are more impressed with the big picture. Btw, the coupling caps are tantalums!

The NAIM 135 sure is unimpressive. No emitter degenerating resistors on the LTP, no complementary output transistors, .22 resistor instead of coil, risetime capacitors, ugh.

I've seen better amateur designs.
