defiantely go for something better than the on board single LM317 for that chip Ray! Poss try a 317 based tracking pre reg???
Personally I'd look at using something with feedback for noise cancellation that can deliver the current. 180mA is also conservative! the reg on mine definately needs a heatsink as it runs really hot!!!

I get alot of TDA1541 based dacs in here with tube outputs etc and non of them sound nice to me. The NOS makes the sound very sterile, it just loses musicality.

Non Over-Sampling. Someone who knows more could explain it better so I'll not try!
The reason some do it is to avoid using the noisy digital filter chip, usually SAA7220. It's usually considered to be an upgrade in musicality but has an audibly limited frequency response and other issues.
If the SAA7220 chip is separately clocked and regged then its sound (or the sound of the whole) can be exceptional, thus presumably leaving the NOS sound in the dirt. I've not tried NOS myself but I can well believe what the others are saying.

The thing is, something like NOS has many in favour and many against. It must be flawed by that logic. Compare to something like a Mundorf Supreme cap, which is universally praised...
The thing that I've always found with NOS is that you get a fast bang for your buck when you remove the 7220 chip entirely. Never tried doing all the work to it as an alternative though.
The chip seems to be so power hungry and dirty that just taking it out gives a quick sound improvement over the standard imo.
Even players where the drawer won't open properly and the lasers don't read very well suddenly start to work smoothly.

Sorry it's gone off topic. I just can't resist starting arguments and nossing is one of the easiest

Yes, we could start another thread on it: to NOS or not to NOS 😀.
But it would be one of the many that are already there i'm afraid. My credo with these things is: try it yourself! If you don't like it: try something else
.
Theoretically oversampling is not a bad thing, but it has to be implemented correctly. I'm not going to take the easy route by just leaving the chip out. First, i'm going to see how it sounds, and then make some improvements along the way. So that's what i'm going to do 😀.

LOL! and long may the debate continue! Each to their own. I like what sounds best to me! I guess if we were all the same with same tastes, same gear, same rooms etc, it would be a little less interesting! 😉
Yes, it would be a dull world... I like your 'Leave Nothing as Standard', I think I am also in that category 😀.
Sorry to gate crash the party! but back to basics...anyone tried the "new" Vishay S -foil resistors yet? They have been a great contribution in my recent amp up-grade. I put this on my wish list for Brent.
I've seen them and been intrigued, but a bit put off by the price. They'd want to be used in super-critical places (and they look fragile). The comments of the guy at Hi-Fi Collective are most positive, he seems to rank them up there with the best but perhaps understanding that it's a metal resistor and will sound slightly different to a carbon-based one ie. more neutral vs more natural.
FWIW I've rarely heard a bad word said about vishay bulk metal foil resistors - before these naked ones came onto the scene.
Hi Simon
I am also interested in these resistors.
I am using Vishay bulk metal trimmers as input load for my phonos with great results (almost as good as shinkoh)
Do you believe metal film is less noisy than carbon comp ?

I'm led to believe that noise level comes down to specific resistor design, rather than the resistive material chosen. If buying cheap/standard items carbon are said to be very noisy and metal film quieter, but both types seem to sound bad compared to "nice" items such as Kiwame, Holco, Allen Bradley etc.
Btw, some people say all resistors sound the same so we're on dangerous ground here - get your flameproofs on, this is quite a conservative forum!! 
Those claiming resistors sound the same also claim caps are all the same 🙂
Also those guys tend to believe cables sound equal and the longer they are the better 🙂
IMO I am experienced or my hears are faulty.

Yes, and the most hardcore also believe amps are the same or close enough to not be an issue. Even some big names around here are in this fairly extreme camp. I had my faith reaffirmed only recently when I modified a PA amp (much better) and then swapped it for a chip amp (totally different sound again). The next step was to biamp with these two and boy was that a step up!!??
I don't believe anyone in this thread, assuming they've lasted this long, would take offence at the idea that resistors sound differently. I used to be a big fan of Shinkoh and would have used them in the pot on my amp but the person who built it wasn't keen to order or couldn't at the time get a small batch. The S-foils are "supposed" to be the ultimate. True there were only a few used in my amp this time. I'll let Brent decide where and if to use them.
