I have a DAC I'm working on that has something like 8 regs per channel. There are three rather simple unregulated supplies feeding them, very similar to the unregulated section of a STEPS. I also experimented with a pair of sigma22 and a sigma11 (yes, crazy) and bypassing the regs and I couldn't hear any difference, in fact the regs sounded better to me depending on how little sleep I had at the moment. I was planning on trying a "TeddyReg" design, or even other similar mini regulators and just haven't gotten around to it. Problem with those, is they are hard to heat sink. I think the key here having just enough voltage head room, so that most of the heat is from current consumption. I changed all regs to be LDOs and thought it was a positive change, and looks to me to be a good choice in this situation as well. Then again, take this with a grain of salt. I'm using ceramic capacitors as bypasses right next to all the DAC chip sockets, so what do I know

yeah, as if someone couldn't tell which was which by the pads alone.. good thing someone else was putting them on his head though.

sure, if it had caps on the input.

asses are animals too man...

pfft.. please take notes from how this double blind between the He and Stax was conducted, then please repeat your tests Reks. HeAudio EH-1.3 & EH-1.2B Electrostatic Headphones - Page 129 - Head-Fi: Covering Headphones, Earphones and Portable Audio

Steve: does the tape ride up and down like it did with the proto plinth you had at my place? Also, it would probably be worthwhile letting the thing "break in" and discharging the battery once and letting it recharge before the weekend. Oh yeah, and it looks great

yes, but you'll have to do some math to see if it will work. Depends on the "gear" ratio in this case, or the pulley diameter to platter ratio. This will tell if the Maxon will be capable to drive. The other issue is eccentricity (?) of the pulley, thereby ensuring that the pulley won't introduce an undulating motion into the table. This would cause sonoriscity failure.

have you actually listened to either?

why don't you ask at a third forum, three's a charm.

Steve: in theory, what do you think about injecting the more porous woods with resin? I did it at a whim, but I think it could be rather interesting if used in the proper places (i.e. my pod).

maybe a bit more detail would be helpful. Do you have the ground wire from the tonearm attached?

I like the LM4562 for I/V (metal can versions) when biased with 2.5mA or so current (class A)... that being said, I agree the above is pretty lame.

that's an understatement it is a player that makes a good first impression, that's for sure.

lithium....

I removed all the ceramic bypasses, replaced the crystal with the Citizen, replaced everything in the original PDF with Black Gates, added another purple Black Gate to bypass the PSU where it enters the board, settled (I think) on a MKP1830 for the 10nF cap, removed the inductor on the board, did the BG|7808|BG psu with the recommended MSR/MUR diodes, added a custom R-Core transformer. I haven't done anything with the LCD yet... working on a case at some point is my next step. Should we start another thread? Also, have you heard the original 47 labs player?

yup, yup, yup. I have 2 transports so I can compare the mods side by side. This is the best way to do things, IMHO.

the level of MisterX's build quality and customer support and his price.

check out the video on the product page... yeah, it has the same capacitive touch screen. Anyways, I heard a few portable players over the past week or so and they all really sucked... I didn't think they'd suck as much as they did... I cannot believe people this this is hi-fi. My favorite believe it or not was the Sony players. I'll be in China for a month or so around Christmas, so I'll be able to try some of the new Korean / Chinese players that will coming out over the next month or so. edit: if you'd like to see it, I could always delay your shipment for a week or so and send it along with the Millet for proper cable sizing

Nationite S:Flo Touch Screen 8GB gotta try it, why not... it plays FLAC after all..

obviously you guys haven't heard cryo'ed ceramics.... duh.

up until now, we really haven't seen the "not for commercial use" phrase abused (in the headphone DIY realm). Now we have. I wonder what repercussions this will have.

I really like the arm board Steve! Looks great!

maybe he can custom order them from Ti ... or is the some other amp

I'd just offer an hardwired version... seems reasonable enough.

sorry, been too busy working a BOM for this project: diyAudio Forums - How cheap can you get? ~$60 assembled pair w/ bamboo enclosures - offer advice. - Page 1
