I think that the Qutest and U1 mini is a great combination if you like the clean, crisp and precise sound of the Qutest as I do...
The T2 may sound a touch warmer...
The Qutest is a custom FPGA implementing the Watts Transient Aligned architecture vs the T2 being a Delta Sigma architecture... Choose your poison...
Either way, getting away from a direct connection (USB) from your MacBook will make a bit of a difference also... You will still be able to stream from your MacBook to either the U1 mini or T2 via wifi/ethernet...
