February 12, 200917 yr comment_205677 What would be the reason behind using a GLite's DPS instead? Report
February 12, 200917 yr comment_205679 the DPS would be a better power supply. Generally speaking with amplifiers, the better the power supply, the better your results will be. Report
February 12, 200917 yr comment_205680 ^ Not to mention it's more convenient to deal with a standard power cord than a bulky wall-wart. I hate wall/floor-warts! Report
February 12, 200917 yr comment_205682 But didn't Justin discontinue making them because the sonic improvements weren't significant (or was it just not cost effective, I forget)? Or different circuit = worth giving it a try? Report
February 12, 200917 yr comment_205688 Justin said the DPS wasn't cost-effective. And don't you think he would never have made a DPS if the improvements (sonic or otherwise) weren't significant? Report
February 12, 200917 yr Author comment_205691 It does not look compatible with the HeadRoom Desktop PSU sitting on my desk, unfortunately. Somebody should ping Pete Millett before trying this. Report
February 12, 200917 yr comment_205697 Elpac only makes one linear +/-15Vdc wallwart IIRC: WM071-1950-D5 Now I suppose that TTVJ could have had Elpac do a custom version, but I would doubt it. Report
February 12, 200917 yr Author comment_205700 The part no. is Elpac WM071-1950 with no D5 at the end. It looks like this, which is different from what you linked above: And the Data Sheet pdf linked on the page you link to seems to be correct and have an image like what I have here. Edited February 12, 200917 yr by Voltron Report
February 12, 200917 yr comment_205703 The D5 in the part number means a DIN-5 connector, which is what the TTVJ pic and your Elpac pic use. Interesting that clicking on the datasheet link goest to iccus corp. who it appears bought elpac. Looking at the commercial lineup, I don't see the WM071 listed anymore, though it is in the WM.pdf datasheet still, but that is an Elpac datasheet. Doesn't bode well for commercial gear using this PSU unless it is an oversight. Report
February 12, 200917 yr comment_205763 Question. So is that line out a loop out or a pre-amp out? Report
February 12, 200917 yr comment_205771 If it was a Pre-Amp output, don't you think it would say Pre Out? Report
February 13, 200917 yr comment_205780 If it was a Pre-Amp output, don't you think it would say Pre Out? I know it should... But voltron said he was using it as a pre-amp. Which basically confused me. Sorry for my noob-ness. So how did voltron get it to work as a preamp when it's a loop out? Report
February 13, 200917 yr comment_205782 Must see inside pics. Bet there are no blackgate output caps... Or blackgate input caps... or bipolar mascquerading as fets... bet there is no $10 usb to audio converter either... obvious fail and its way to cheap... and it works too... Report
February 13, 200917 yr comment_205784 Yeah but my SS-1 has like 16 hand matched mosfets. Mikhail told me this himself over phone! Report
February 13, 200917 yr Author comment_205785 The output is in fact a pre-amp output even though the label says Line Out. I have mentioned this to Todd and I assume that he can correct it on later rear plate orders. Report
February 13, 200917 yr comment_205786 I don't think mikhail can count... 6 boards with 4 bipolar per board... Thats 24 Now what did you say mikhail was doing with his hands ?? Report
February 13, 200917 yr comment_205788 The real question is whether the preamp output is buffered or not. It could just be the output from the pot... In which case it would be high impedance. Or the output could be directly from the input selector switch. I don't consider either of those 2 options a real preamp... Report
February 13, 200917 yr comment_205799 Is it me .... or does this amp look both ugly and cheap? The volume knob really looks funky. But here are the pics for the time being: Report
February 13, 200917 yr comment_205801 Is it me .... or does this amp look both ugly and cheap? The volume knob really looks funky. Well, looks don't really have any impact on sound quality right? Yeah, no bling... here all the $$$ goes inside!! ps: I also like to have nicer looking stuff, but I understand Pete and Todd's thinking behind their products! Report
February 13, 200917 yr comment_205802 Huh, the power switch is still done opposite of what seems right. It definitely doesn't look fancy (and looks downright gritty) I think it could work. It's in a competetive price range, and if what could have gone into looks went into sound/quality, then it could be a very good option. Report
February 13, 200917 yr Author comment_205808 OK, it doesn't have style like these two, but my pictures are crappy and done at night with bad lighting. Still, the TTVJ look is definitely utilitarian and nobody seems to like the volume knob except Pete Millett because it is used on the 307A amp as well! It was just something to get posted, but the amp does not look like it was built by Accuphase or Luxman. It is similar to my EC/SS in level of looks/style, although I keep asking Todd if there is some reason the DIY guys like Nate can come up with beautiful one-off cases and face plates like the recent Beta22 for tyrion. He seems to believe it would be too expensive and obviously believes the money is better spent on internals and design. Report
February 13, 200917 yr comment_205817 If you're feeling especially proactive, you can always recase it yourself? Report
