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...

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...

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?

This Ebay item is an "alternate source" for the Shanling SCD-S300 that is available at retail at a limited # of dealers in the U.S. for a much higher price. Regardless of the source of the purchase, has anyone tried this model? The DAC used is one of the newest ones, and the specs look...

Would anyone be interested in laying out a new board with these changes: Use 6 of these for C4: 10V, 330uF, 6 milli-ohm ESR @ 100KHz. Use 27 of these for C1: 16V, 47uF, 35 milli-ohm ESR @ 100KHz. It appears to me that the PPAv2's power supply design relies on the active devices' high...

Does this mean no more Sony headphones? Maybe worse, no more Sony audio equipment period? Quoting June 24, 2005 WSJ article: http://online.wsj.com/article_print/...368003,00.html Sony Corp. will narrow the focus of its research and development to only promising areas such as...

With the arrival of PPA v2, there is a need for a curve tracer. What does everyone think is the ideal used unit that can connect to an oscilloscope?

The Intersil HA3-5002 buffers placed in parallel each have their internal negative feedback loops. If their gains aren't very close to each other, the buffers' outputs will end up fighting each other and there'll be some current drawn from one buffer to the next, instead of going between buffer...

http://www.analog.com/UploadedFiles/...45AD1955_0.pdf I am presently using an evaluation kit of the above SACD-capable DAC, feeding it via Toslink at fs=44.1KHz only, with CD data. The sound is wonderful. Now I want to drive it with DSD data from a SACD. But there's just no place that...
