and probably less expensive...but it makes upgrades more difficult when everything, including the power supply is contained on one circuit board.A few years ago I was considering trying a phono stage (not the Shiit) that was getting some positive press. I decided against it for the same reasons we're discussing here, because it was built with an external AC rather than DC supply.
I'd much rather have the option to do as you suggested, Lew, and build a high quality external DC supply, without having to cut traces, solder in jumpers, etc, likely destroying any resale value in the process.

Certainly more savvy than I am with regards to what they are doing. There's probably not that much to be gained by fiddling with the Schiit or the iPhono2, for examples.

Yeah Lew, you're probably right. Why bother trying to improve equipment. He is probably already using the very best filter caps, like Elna Silmic II or Nichicon muse. I'd bet dollars to donuts he is using soft recovery diodes or Schottky. Probably using metal foil resistors also. The transformer is big enough and the thin wires on it are about as good as you can get on this or any other planet. Maybe even the planet you are from. Or maybe you could be full of Schiit?? Like WTF. Why is there even a tweaker's asylum forum? I was foolish in the past to think it was here for tweakers. Tweekie666

requires a sharp analytical mind? Sure, there may be some compromises on parts cost, in order to meet a price point for marketing the item. And if you want to "upgrade" the parts quality, go for it.
You want to cast me in the anti-tweaker role. I won't play that part. I wrote elsewhere that a completely discrete outboard supply would be the no-holds-barred way to go, if one is so inclined. For those who are put off by such notions, because they lack skill, knowledge, or experience, the product probably has been well thought out to begin with, if the company building it is reputable, like Schiit or iFi.
Yo Lew, my sharp analytical mind doesn't understand the relevance of your question. I think swapping in better sounding parts makes things sound better. "The only thing he did was change the transformer. We went from a 100mA transformer to a 10A transformer"exactly the same voltage, the circuit was drawing no more current"and the DIFFERENCE was just STAGGERING. To this day it's one of the biggest differences I've ever heard." I kinda like this quote from the Paul McGowan link posted by 1973shovel. Pure hyperbolicness I guess. Why even bother trying to make one's system sound just a tini wini bit better? T456

.. in fact it's possible to completely screw up a power supply by fitting expensive high-performance components, in much the same way you can mess up the handling of a car by fitting expensive alloy wheels and low profile tires.
I think his point is a little more subtle, maybe. There has to be a cost/benefit review before undertaking costly improvements, like adding a $100+ power supply to a $50 hock-shop headphone amp. (I don't have a huge junkbox any more that I can pull parts from.)
I have no doubt that an outboard high-current DC power supply would bring a sonic improvement, but the ultimate performance level it can achieve under the best of circumstances is probably not going to be worth the cost.
I think that a **cost-appropriate** level of improvement might be to use nice fat transformer and some nice fat wire, hardwired in, like I was thinking originally.
