for me it was not the smartest thing to do, to borrow the mscaler for a few days..... one's you get used to that sound, you don't want to go back! that mscaler borrow has cost me dearly , I got a good deal, almost 2000 off (was a shop demo, but looked brand new, only occasional used).I tend to agree but will be fair (to me) to mention that there is still another good option - iFi iDSD Pro. Like a stand alone solution that may upsample, and with the versatility of filters and tubes it is very good for many different scenarios. I am using both, TT2 and iFi iDSD, for headphones and speakers and still cannot decide which is better. iFi IDSD gives me bigger versatility when swapping headphones and when I want to upsample (I do not have the Mscaler ), also smoothness is remarkable; while TT2 is unbeaten (to me) for neutrality, detail, air.
I also have a seperate Burson 3xrgt as amp+supercharger, have a hard time to choose which I like more, was planning to sell the Burson, but the tt2 and Burson have both their own quality. I know the Ifi Idsd and that is a sweet device too! sounds very very good, very smooth indeed with the tube
