NAD M5 CD SACD Player This one should strike the right balance between quality and features. And it supports HDCD encoding as well. Has anyone heard it at all? Maybe during a trade show, since production quantities haven't reached the retail channel yet?

Check out Reference Recording's The Rite of Spring, The Firebird Suite, and The Song of the Nightingale with EIJI OUE and the MINNESOTA ORCHESTRA in HDCD format. The performance is meticulously well crafted, at a slower tempo than is common for these pieces, with a story-telling quality...

http://wdch.laphil.com/tix/performan...il.cfm?id=2355 I just came back from this concert. Did anyone else attend tonight? (thursday) The concert hall's sound was very good, I guess mostly due to an open layout where the orchestra is surrounded by the audience, hence minimizing short-delay...

Modern electrolytic capacitors are built with low ESR (equivalent series resistance), making them better suited for supply bypassing in audio amplifiers. All the big name component distributors have sections in their catalog showing low ESR electrolytic and tantalum capacitors. For use in...

The charge Q = C * V in your power supply's filter caps must be proportional to the output power P = V^2 / R you expect out of your amplifier. Hence both tube and solid state amps need the same charge on their power supply filter caps, but differ in their voltage and capacitance requirements.

Referring to the original PPAv2 schematic, I believe C4 is the power source for the opamps, configured to act like an ideal voltage source. Then R8 and C5 act as a lowpass filter to supply the opamps, thus attenuating any high frequency supply noise appearing on C4, even though that is much...

I've read this past week's postings, and have a question about Mahler's 9th symphony that I hope someone will post an opinion on. I am looking for a recording of the 9th symphony that has similar qualities to Leonard Slatkin's recording of the 2nd symphony with the Saint Louis S.O. That...

http://www.superfi.co.uk/index.cfm/p...roduct_ID/1649 Has anyone auditioned this unit? It seems not to be offered here in the U.S. Or is it just a new model that'll eventually make it here?

I agree with you. If fully enclosed, the output transistors will get too hot. I plan to lay out a new board to have those transistors mounted at the very edge of the board, like many of those Chinese headphone amp kits, so that the output transistors can be bent outwards and mounted onto the...
