I had the Qutest for a few years and decided to upgrade. Compared the TT2 + M-scaler to Lab1 dac and MSB Discrete. What can I say - I'm a big fan of the Chord sound. I'd say the TT2 got me 90% of the improvement and the M-scaler 10%. Also powering both with the Hypsos Ferrum - definitely an upgrade worth considering.
I'll throw you one more idea. I had an McIntosh MA-8900 integrated and I tried the TT2 as the preamp into the power amp inputs and it was surprising and amazing how much the soundstage improved in width and height. I ended up selling the 8900 and bought the MC-275 and again the soundstage got bigger, but this time also added depth.
