Mytek Dac going Ac to DC power.

What high end supplies did you try, and did they all sound about the same as Astron.?

+1 on the Astron, picked up a used RS-12M on ebay for $71 incl. shipping for my Brooklyn + DAC.  I difference is very noticeable in both my main system on digital and in my small room vinyl system using the very good MC phono section in the Brooklyn +.  Stock voltage is 13.8, but I used internal adjustments to recalibrate the front panel meter and reduce the voltage to 13.  Clearer and more dynamic.  You can also look for model #RS-12A, same thing except no front panel meter.  The Astron website lists all their current models plus distributors if you prefer new.  Also just ordered a used LS-10A (28 volt) to replace my Dell laptop power supply, curious to see what improvement that makes to my digital system per recommendation on this forum.

I own an Original (Non +) Mytek Brooklyn as well as a Teradak 12V 10a linear PSU I used to use to power a mac mini stack.
While Mytek apparently recommend 6amps or so, would my 10a PSU be usable with the Brooklyn or is that just too many amps?

Hey @Madinuk2007

The DAC will only draw the current necessary, so in theory even a 100A supply would be OK so long as the voltage did not exceed ~ 14 V .

Best,

Astron +1. 
love this made in Irvine, CA little tank!

I bought an Astron RS-7A used but like new and retrofitted to enhance power delivery:

1) upgraded all wires to mil-spec silver plated 18/22 awg ( input / output use 18awg, voltage reference for LM chipset can be 18)

2) removed original filter cap (Nichicon 12000uF/25V), and replaced with 4 Rubycon 6800uF/80V in parallel. I ordered some NOS RIFA PEH169 10000uF but unfortunately they were way too big for RA-7A. 

3) ditched speaker post voltage output, changed to aviation connector GX16-2pin and make a DC12V cable with 5525 dc jack. 

4) adjusted to Dc12.0V output. 
 

all materials plus shipping is $60-ish. 

And I can obviously tell the sound difference versus AC 120V input into build in switching power - ouch!!! Gross!
