not touching that post above me When I click on threads that I have read, they do not go to the last page or preferably the first unread post automatically. Is this something I can configure, or?? Chris

Happy Birthday!

IIRC, the async USB does a much better job of minimizing jitter. Gordon Rankin (wavelength) discusses this quite a bit on diyhifi.org, if you care to look.

Yes, nice job and I'm sure alot of work Todd!

Hmm, isn't the CD capacity determined by filesize? Or is it a fixed number of minutes? I thought if you put compressed MP3s on a CD-R you could get a shitload of music on one? Or are you saying that because it is Redbook, you are limited to 80 minutes?

Per title, and no, not DVD-A, just plain DVD. I have a couple of concert films that I would like to extract the audio to CD (lossless). This is on a Mac. I played around with OSEx and mac3 something or other last night and managed to extract AC3 files for each track from one and get them converted to AIFF, but it was somewhat less than intuitive. I haven't compared the sound of said CD to the DVD yet, but it seems fine. Also, the total content was a bit outside the range of a 700Mb CD (at 1:30). If I were to compress it slightly to try to fit the whole thing on one CD, any suggestions? If I extracted the AC3 to mpeg4 (m4a?) would that save any space? Thanks -Chris

Marc, I'm not sure about the Rotel RCD-855, as that is what I have, and mine is not an S1 (it may be an R1, I'd need to look at it again). Some lists show this as a TDA1541, not TDA1541a. It most definitely is an "a". Hence my request to spritzer that I'd take those lowly S1's off his hands for him Your plan of listening to plain TDA1541as is probably about the best you can do now, particularly given the fact that any double crown on the market would be suspected fake. There was a guy on pinkfishmedia that was testing some S2s for a potential group buy and determined that the ones being tested were not any better than the known good plain ones he was testing against, so he advised to abort on the buy. You might be able to determine what he was using to test however. http://www.pinkfishmedia.net/forum/showthread.php?t=40114&highlight=1541a&page=6 Oops, this was S1 vs. plain. Still some valid bits however.

You can remove the single crowns and send them to me. That will free you up to track down a pair of double crowns

You've got it backwards... supposed to have no power at work, but power at home

Congrats Nate!

A single 18V adapter will not work. For practical reasons (see so many "fail" reasons), two 9V adapters will not work either, unless they are floating (the - not tied to ground). You would have to tie the + of one adapter to the - of the other and take the ground at this point... if the adapters are tied to ground, they are not going to like this... See above, but IMHO no. Also, you would want linear regulated AC-DC adapters, so their price is higher that what you are probably looking at.

Grawk: hope your wife is OK. Sorry about the dog. Reks: Congrats and good luck!

You need 18V; more importantly, you actually need +/- 9V. The batteries in an RA-1 are in series; the connection between the batteries forms the ground.

Hmm, that must be the cause of what I was seeing. When I first popped in (~9:50pm CDT), In the Recent posts, I see a post in the beatles vs. stones thread by morphsci at ~8:50pm. I go to the thread, and the last post in there was by hungrych, and no posts by morphsci. I was starting to look at what I was drinking...

Interesting poster on HF on a band he claims the Beatles ripped off: http://www.head-fi.org/forums/f9/most-overrated-bands-332349/index5.html Andrea perhaps?

Not necessarily, as it seems alot of what you mention in music I like... just not the '70s or later Stones. Interesting, Grand Funk was the first "famous" band I ever saw live...

The Eagles... :vomit:, though with your memories of your dad I can see that. For me, it will be 'til Hell Freezes Over before I would make the effort to play them. All the sloppy albums I hate! The Stones also have the sloppiest "pro" drummer I can think of...makes Ringo sound like Bonham/Moon/Mitchell/[insert other good drummer here].

Same as Deepak, though the only Stones I really like was the 66-69 period. Hate their '70s stuff, out to current pretty much.

I'm not sure how this would work as a preamp... seems somewhat massive overkill from a power perspective. Have you ever looked at something like the Pass Aleph P1.7 on diyaudio? The boards aren't available anymore, but the layout was pretty easy on them... As Nate mentioned, I would be really tempted on the Dynahi to use the sigma22 PSU(s) instead of the original, as blowing up $20 OPA541s isn't real enticing to me, even though I have the boards.

Were yours (jp11801 and postjack) Dynahi's or balanced (dynamight)? Dammit, wasn't looking for a headphone project, but since I already have most of the stuff....

I still have a few (of each)... Since I have the heatsinks from the GB, etc., I should probably get around to building one one of these days The only Dynahis I ever saw in person were KG's and Dan Gardner's Dynamight. Of the commercial pics, sft's probably looked the best, the Veda's looked OK, and trevornetwork's.... well, lets just leave it at that

good luck wreks!

Dan Gardner still has boards available (as do some of us ). The input dual FETs (2SJ109 / 2SK389) are no longer available, but can be replaced with singles (2SJ74 / 2SK170), which have also been discontinued. IIRC, the only commercial builder that I might have trusted was sft, and I'm not sure if he is still building them. And as mentioned, more interest in the B22 these days.

The compensation cap is in parallel with R4, so if you tuned gain by varying R4, you could simply have appropriate comp caps in parallel with those = mind-numbingly complex. Of course, you are correct regarding the wiring, etc., particularly if more than one choice is desired. If you did it with relays on a small PCB you could keep it quite close to the area on the B22 board. Another possibility would be switchable series resistors on the input in front of the pot, with a short being one choice...

Since the attenuator (pot, stepped, whatever) is a voltage divider, it is the ratio of input to amp and amp to ground impedance that determines the volume. Therefore, it doesn't matter how big of pot you use in terms of volume; they are all the same. The different sizes will effect noise, etc. however. Tube stuff typically uses the larger values whereas SS stays at or below 50K (typ. 10K). For the B22, can you not play with the feedback resistors (looks like R4 / R3) to control gain?
