Hi Tweak1,
I just bought the SMSL Transport, I really like it. I have Genelec 8330 montitors on my desk with a Genelec 10inch subwoofer. These speakers are digital with an internal AKM dac so you can run the SMSL through the AES/EBU output direct to the monitors digital input. Superb,
Recently I have been subscribing to Amazon Music but the SMSL Transport outperforms streaming via the Singzer SU6.
My upgrade has been the addition of a cheap GPSDO external clock. The one I have has 4 x clock outputs (these are very cheap). For my main system, I have a Gustard X-30; therefore, you can use the same external clock to synchronise them, resulting in superb results.
I came across your thread because I was choosing either the ET3 or the 2000T. Apart from remote issues, I am not sure which one you think has superior sound. I mainly chose the SMSL because it has the external clock option. I am very happy with it. Right now it's playing Pink Floyd Live at Pompeii. Fantastic.
Btw I Thought you may have got more feedback on this item, but maybe its considered a low status item.
