Great but it seems you didn't forget the mandatory Qutest PSU upgrade...
Mandatory PSU upgrade?? Rob Watts himself disagreed but ok, what a load of unsubstantiated ***.

The stock PSU is fine for all intents and purposes. You guys should ease up on the faerie dust...

I use Lifatec and its 100% stable on 24/192 and DSD over DoP (which is 24/176), I use it on RME ADI-2 DAC though playing directly from computer.
In agreement with MagnusH - I use the Lifatec as well with a Mac Mini and the Hugo2. I am able to get 24/192 and DSD64.

Just FYI, this is the correct link for USB card:
https://jcat.eu/product/usb-card-femto/

P.S. Many people spend more than 435 for some USB cables or USB filters...
Don't worry, I am fully aware that some people spend eye watering amounts on those cables and filters.
The point that I obviously failed to communicate effectively, is that I can already obtain excellent sound quality using optical output from my PC, so I shall not be rushing to spend an additional 435 euros, in an attempt to get similar performance via a usb card. If the card had cost say 25 euros, then it could have been an interesting exercise from a curiosity point of view, but not at 435 euros.

Good to know they updated the cable. When I had mine about six years ago, it wouldn’t pass 24/192 consistently, especially DSD. I spoke to the engineer there, and he admitted this was a limitation of the design, but told me they hoped to rectify this at some point in the future.

I may need a toslink again for a new hookup, so I’ll try out the Lifatec again; I did prefer its sound to the Sys Concept.

I`ve upgraded to Hugo TT2, so if anybody wants Qutest - mine is for sale at trade forums.

Phew! Actually Ive just made an order of the lifatec toslink and its reaching jakarta as of now, should be delivered in one or two days now after getting through customs. Currently running my old EMK optical and it clips regularly when running 24/96 out of my MBP. Looking forward forward for the lifatec. @jwbrent you have scared me for a bit there regarding the lifatec not able to handle 24/192

@Ragnar-BY How much of a difference compared to your qutest?! I was originally intended to purchase the TT2 to run as a preamp in my system before deciding to ditched the preamp/amp combo and just went with an integrated. All the best with the qutest sale. It should be gone in no time!

Well, I`ve bought Hugo TT2 and M Scaler, so this fight was not fair from the start. Even without M Scaler TT2 is really good. It is a better DAC and for head-fier it is also an outstanding amp. M Scaler sounds good with both units, but on TT2 it`s effect sounds like real magic. On the other hand, I must admit that Qutest is still a great DAC with a great value. This little brick is the most affordable ticket to the land of high-end DACs.

I would say that if you can afford TT2 - go for it. But if you don`t need headphone amp, pre-amp and full M Scaler magic - you can happily live with Qutest.

Yes, I messed up writing that. I had forgotten how long it had been since I owned the Lifatec cable when it couldn’t handle 24/192. After my post, I realized it had been six years since I owned this toslink, so my apologies. I really am happy to hear it can transmit 24/192 since it sounds excellent.

@Ragnar-BY thanks for the detailed explanation regarding TT2 / Qutest. Ive been wanting M Scaler, but I should ease on the audio spending for now, maybe an addition of the m scaler to the qutest next year. Quite happy with the setup Im running now. Just breaking in the diablo 300, waiting for a proper separated grounding to be installed, installing an isolation transformer in between the main ac and main room receptacle, and the lifatec optical as the icing on the cake.

No worries at all. Looking forward to install the lifatec in my system once the int amp breaking in is done.

As a person who despises the sheer lunacy in hearing a difference in cables...I can hear a difference in SOME cables. Which is why I bought the lifatec. Worth it.

Thanks dac64. This issue is abit clearer for me. So i will try setting the qutest output to 1v and 2v and what are the things that i need to lookout for specifically? Thanks
You may want to look at the output of gryphon cd player or dac.

Smart suggestion! Actually the diablo 300 dac single ended output documented at 2,15V which makes sense since I did changed the output on the qutest at 2V yesterday and I thought it sounded the best. And this fact confirms it. At 3V the sound gets distorted and at 1V it sounded too weak I had to crank the diablo way up. Thanks @dac64
