That looks identical to the stock supply, if your looking for improvement I would say dont waist your time. There are no short cuts to upgrading the PS for improvement, my low noise DIY linear supply ran about $200 and provides a nice bump in performance.

I dont think there is any free lunch with regards to an external PS, I doubt a $50 supply will be noticeable.

I wanted to try an isolation product but wasn't willing to spend a lot. Bought some Herbies Tenderfeet Booties for less than $25 and its the best $25 tweak I have ever made!! Highly recommend.

I hadn't gotten around to trying the different voltage settings till now. I set it to 3v and it works so much better in my system, now I am not going over 12 oclock on my preamp and seems to have more impact. I love the various settings on the Qutest!!

I felt the 650's were horribly veiled, I picked up Wywire Red cable and solved the problem. That 650 cable is definitely a bottleneck!

I read a post earlier in the thread about isolation and Herbies Tenderfeet. Isolation products can get crazy pricey but wanting to give it a shot I contacted Herbie and he recommended the Baby Booties. I was a bit skeptical but the price was right so I purchased 4 pieces. I am pleasantly...

I am using this one. :) https://www.ebay.com/itm/Micro-USB-5-Pin-Male-To-5-5-x-2-1mm-Female-DC-Power-Converter-Charger-Adapter/182476799414?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

Please share your thoughts between the TT2 and Qutest. ??

I had to reboot the IsoRegen several times before my system connected to it.

My comments need to be taken with a grain of salt, the Spring had already left the building and I was just going on audible memory. As someone already mentioned it probably just comes down to personal preference, I just never connected with the Spring.

Hey Tbone welcome to the thread, Im a recovering Holo Spring addict as well! :) I felt the Qutest was a tad more musical and is fitting in nicely here. I am still messing around with settings in Jriver and HQP.

Given the opportunity I would highly recommend a trial of the Wywires Platinum USB cable. I believe its strength is in the bass reproduction but nice balance overall, it is a bit pricey though. I got mine on sale. @ HumanMedia...

I had positive results using IsoRegen on my USB connection also.

Cardas XLR adapters are the go to for audiophile.

Jon I am using a DIY AMB Labs Sigma 11 PS with a Wywire Juice PC. I think I used a 100va 5.6amp transformer. https://www.amb.org/audio/sigma11/
