A CNC machine? Not that... oh, wait...

Nice way to answer the question (not). f-tards.

Ahhh, I see. Yes, 100 ohms would be a good idea then, much like the series resistors used in many CDPs ahead of the muting relays.

Happy Birthday!

You would be surprised at how much stuff is really just designed from the datasheet examples. These are often wrong. Remember it isn't usually a design engineer doing the datasheet work, and even for new parts, the examples may be retreads from decades ago. Also, the reasons that things are done a certain way in commercial gear may have nothing to with sound quality or other aspects that you would think would have been accounted for. For example, that transformer on an SPDIF output may be there more to meet FCC part 15 testing rather than its suitability as a pulse transformer.

Just out of curiosity, what is the purpose of these resistors? Impedance?

The Headamp V2 board I have just has a spot for a series resistor per channel (10 ohms) for the pre out spot on it. Otherwise, no difference. I would doubt that resistor is critical either. If yours is built on a V2 board, there should be a spot on the back left edge of the board for this.

2SC3381 datasheet doesn't show any 3 legged for this... it would be kinda hard to pinout 2 BJTs using only 3 pins I hear ya on finding these... I was trying to get more in case I decided to do Dynamite. I decided to just do 2 ch Dynahi instead. Use 2SC2240 pairs to replace these (2SA970 is the complementary).

There, FTFY Smeggy!

I own VR-4 GenIIs, which are probably 3-4 generations prior to these (so maybe not valid or worthwhile). I've been quite happy with these and bought them without listening to them My younger brother had a pair and recommended them to me; since I trust his hearing, I thought it should be fine. It was.

Hehe... Whatever happened to that guy anyhow? Tariq Aziz was it? Kinda lost track of him after the invasion.

Steve, Thanks for the offer, let me think about it after buying another Rotel... I always wanted to hear something using AD1862s (and the PMD100), those being Jocko's fav. dac chips

Pure win!

Our one Fry's here (Lombard) is kinda the same way. Plus they seem to not restock parts. I went back looking for a couple of trimpots 2 months after buying the last ones they had. They still had not restocked

Any of you happen to snag one of these? I was thinking about it but bought a Rotel 991 prior.

Interesting interview in Chicago Trib with Lars (Metallica). His comments/perception of the compression/loudness issue is priceless. Metallica's 'Death Magnetic' too loud? Too bad! -- chicagotribune.com

Glad you like them... Nice stuff.

No opinion (or knowledge) on the Zyx->Candela. Just wanted to ask you how you like your Odyssey toys?

Does there? Blanket statements such as this are very dangerous. Just because something is available and expensive (or not) doesn't mean it is good.

The data portion (i.e., the music) of the S/PDIF signal is digital. Most people forget about the clock (running at 2.8xxx MHz) which is riding on the S/PDIF signal; this is actually RF and is analog in the sense that it is the timing and not the levels that are of interest here. Very poor design (clock and data on same signal), but its what you're stuck with. I normally don't use a sep DAC, so I can't comment on different transports, etc.

Nice review. I'd like to hear a Capitole and an Andromeda.

Do your homework... alot of going out of business sales are higher priced than what you can find elsewhere. Remember the liquidators are trying to satisfy the creditors. Going-out-of-business sales are not always the best bargain -- chicagotribune.com Matches my experience.

You're good at stepping back and getting to the crux of the matter, aren't you? I agree...

You don't even have to call them... you can schedule a pickup while you are setting up the shipment and printing your labels out online.

It was -14F air temp here this morning; supposed to be a bit colder tomorrow morning. Not much for wind fortunately, but I get into my car in the garage and get out in a parking garage at work, so don't have to spend too much time outside and rarely have to clean the car off. Winter still sucks however. Nice thing about getting this cold is when we climb back up to around freezing (this weekend) it feels pretty nice out
