me too. fantastic charger.

heh. I think the replies to this thread got lost at some point. Anyways, I'm still looking for a preamp project that can handle the above. I think the preamp I posted here: http://www.head-case.org/forums/speakers/2471-preamps-3.html#post73554 is probably the most accessible project out there. I agree with Kevin's comments but don't really know of a good project off hand that will address his design concerns and get me the specs I need. So, last call for projects!

are you going to try and pitch correct it?

There were so many pressings of "Time Out" you should be able to find a nice mono version. I found one at "Half Price Books", so it's definitely possible. Also, at least with classical, talk about massive bass that mono recordings have, and the clarity really comes with a nice mono cartridge.

nope

what makes you say this? Kinda a generic statement. I know people making lots of money in the NSA, for example. edit: aerius already dinged you on this one..

yay for me!

that's a mouthful.

what about 20th century music that was written in the style of the classical period, like Prokofieff's (I prefer Prokofiew for some reason, why is that?) Op. 25?

i think this needs to be moved into the DDIY category...... wah? is right...

1/3 of a Hammond chassis at that

I could produce any sound signtaure you wanted me to as well, if you gave me $20k and 2 years.

anyways, sorry to derail the thread... my point being that Kevin is a smart guy and it's not like he doesn't know about any of the super-reg power supplies, and there is at least one case where a simple supply can sound better... soo...

swapping out the transformer is no biggey and if there is a model that vt4c / "whatever the ebay seller is that's the same guy" sells, then it's cheaper and faster I bet you can find a dual 18 VAC or something that will work and get it shipped for around $50 or less.

two sources are Kitamura Kiden and vt4c. The KKK [ ] transformers I've found NOS or pulls from Ebay or surplussupply.com. I've also contacted Custom Magnetics, Inc. but haven't really acted on anything yet. I really like the vt4c, but expect a 2-3 month wait on a custom job though. Their specs are also a bit liberal... I'd figure 80% current draw that they state and then subtract another 15% for safety margin. I'm talking on the order of 100VA or so, for oversized. For EI I've used various Hammond transformers... Here's the thread: diyAudio Forums - Finally, an affordable CD Transport: the Shigaclone story I'll be upfront and say I'm somewhat a Peter Daniel fan-boy :)

yeah, it's strange now that I have a number of digital projects you find a lot of stuff just by playing around. The above is one example, another is how much better EI and r-core transformers sound than toroids, _for digital_, and how much better oversized transformers sound. YMMV of course, but it's been a fun and eye-opening experience for me to just try things and not just grab the thing with the best "specs" out there and be satisfied.

yeah, agreed. I don't know what the deal is... there are a particular digital build at diyaudio where people are using a simple LM7808 with Black Gates on each side, and I was skeptical and setup a jig to A/B and it sounded much better than a sigma11 supply to the 2 or 3 people that were over at my place comparing. I don't really understand it myself, but felt unmotivated to really find out why.

the question would be how well does the sigma11 perform with small current draw. has anyone seen any tests on this? I tried a couple of the circuits on my DAC that requires 6 power supplies and the sigma22 didn't sound quite right. edit: heh, my psu looks very similar to the RAKK psu, but with a preregulator and a r-core transformer.

everything that this advertisement writer ever pitched:

I think mono blocks would be harder. Since you have 2 channels on a single board, so you'll either have to use L brackets on each end and align that to the heat sinks on each side, or some weird single heat sink design. My experience is mounting directly on the heat sink is much easier to do, and less error prone.

my heeeerroo.... saving the ESP-950 from FOTM once again!
