Sorry for the delay but I wanted to listen to a variety of music whilst comparing solo Dave to TT2 + Mscaler side by side. The upshot is that for me the sheer transparency of Dave wins through. Of course the TT2 and Mscaler combination is magnificent and is rightly hailed as being tremendous but compared to solo Dave there is a loss in transparency that I would not be willing to trade. Listening to individual notes and instruments the Dave gives so much space around them where the TT2 combination seems to lose out on this and to me even possibly seems a bit 'plummy'. That is perhaps the warmer presentation that many people like with the TT2 Of course there is plenty of bass with TT2+ Mscaler but so there is as well with Dave. However with solo Dave the bass is just so much more defined. It is the same for me with the the top end and mids where I feel that a bit of detail gets lost with the TT2 HMS combo. Now, this is all a very personal thing but I have lived with Dave and TT2 since they first came out and also of course with the Mscaler. However, ask 100 people and you will probably get 50 who prefer TT2 + Mscaler and 50 who prefer Dave solo or indeed I might me the one person and the other 99 prefer TT2 + Mscaler and so I am very wary of influencing you too much but for me at least the solo Dave listening has today just reinforced what a class act it is. This takes nothing away from the TT2 + HMS combination and I emphasise again that this is a very very personal evaluation and YMMV applies more than ever. Not to be underestimated is that if you get a solo Dave then you are more than half way there to the killer combination of Dave and Mscaler! If you bide your time end keep your eyes open you could even get a bargain second hand Mscaler . . . . . By the way I was using the TT2 Filter 1 throughout and I was using the USB to Dave and Mscaler from my Innuos Zenith SE which does not have optical out. Everything was listened to through my Pass Labs XA60.8 monobloc amps and Spendor SP200 speakers because I do not use headphones. I also used a variety of connections between TT2 and HMS including stock cables and other connection methods.
