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?

Sorry to hear about your grandfather. My deepest condolences.

So the Anagram DSP is adding interpolated sampling points to the Redbook data? I can see how this might smooth out the output, but is this viable to "distort" (in a good way perhaps) the actual recording? The reviewer did seem pretty clueless I would agree (DAC-less CDP... hehe)

I couldn't even find the marketplace... then I read the FAQs. 50 posts for access. I have had a login there for some time, but have never posted.

Postjack: You had mentioned in another thread regarding Genesis pressings that the Seconds Out pressing GECD2001 was your favorite? Any hint as to how to track this down? In searching, I found that this was released on Virgin in 1994... same year that the definitive remaster was released (which is what I have). These are definitely different pressings? Thanks, Chris

I'm not really sure. Looking at the manual online (at twisted-pear), it says: '--------------- Output Characteristics: The output of the buffalo can be used as a voltage source or a current source. Best DNR and THD will be achieved using it as a current source. The differential output of the buffalo is 0.924*1.65V (3.1746 Peak) + 1.65 DC bias and the series output resistance is nominally 195 Ohms at each output. '--------------- Doesn't say whether you have to provision pins/dip switches/programming to select which mode you are using... and from the schematic, it doesn't have different output pins that I can see.

I'm not Filburt, but in answer to your question, I believe they are the same. And I'm not sure who Gilbert is that he is referencing. Current steering basically work much as passive I/V does, with the exception of current mirror(s) actually providing the driving current for the I/V resistor, thereby not loading the DAC output and presenting a (hopefully) very low impedance to the DAC. At least that is my limited understanding of it.

Good to hear!

Seems to be a DB-15 connector? When looking around on Digikey, there also seemed to be a DB-15HD? Not sure what that is about... When you mention that the plugs you tried wouldn't seat fully, you mean the pins?

Have you ever heard one of Pedja Rogic's NOS DACs? Strohmie's CD player / Dynamight had one of these in it. I'm building one, but have never heard one and conceptually I'm not sure I buy into the NOS hype. Wait-- why am I building one???

Aww man... get back on it. I've still quit since January. But I do understand... there have been several times... :smoker:

Nailed it!

That sucks to hear Smeggy. The first band I played in starting when I was in junior high had a really good guitarist who wound up being allergic to guitar strings... he would develop a rash much like what you are describing. He could avoid it by wiping the strings down with rubbing alcohol (can't remember how often he needed to do that, once a set or maybe once a night was enough). Don't think you can wipe the wood down like that though... hopefully you can figure out if it is a particular wood.

I've only printed one or two on plain paper, and they looked good. I'm not into photography like you and others here are, so my eye for such things is probably lacking...
