Default Opinions and ideas needed about modding Muse DAC..

Hi all. I am a DIY tube guy and a decent electrician but I am starting to get the digital bug. I purchased a NOS DAC off of Ebay. It is called a muse mini DAC and I believe that some of you are familiar with it. It is the one with four DAC chips (TDA1543s) I have some plans for the little DAC as far as modding goes and I have a couple of dozen questions. Firstly I don't use optical inputs so I was going to remove the optical input and jump out the pad to go with SPDIF exclusively. What I would like to do is have two coax inputs and be able to switch between them. I am somewhat of a minimalist and I think that a good quality switch with gold contacts should do this with no problem. Here is the candidate that I have in mind:

Digi-Key - 450-1382-ND (Manufacturer - TT11DGPC9T1/404)

Secondly I would like to improve the regulation by adding a couple of Burson Super Regs in place of the regulators that are on the board and lastly I want to feed it a relatively clean 12v with a little kit from Glassware which is just a simple regulator using a LD1085P. I want to mount all of this in either a different single enclosure or two separate enclosures for the power supply and the DAC respectively.

Later I may try Film caps on the output instead of the electrolytics and upgrade some of the other components. Am I off base on any of the things I want to do?

head-fi (Mini Dac TDA1543 X 4 NOS)

importantly, use 9v depending what they ended up putting on your board.

My personal finding where that NOS from 44.1 material sounds bad, usually with distortions and un-natural aliasing sounds, that are not present in recording.
Also 1543 are very cheap/poor performance DAC's (THD+N= -75dB, SNR= -90...95dB), even using four of them is not ending up that great in the THD part (helps only the SNR part).
Especially followed by passive I/V, tubes and no filtering stage... I don't think will be anything exciting.
