Okay, guys lets get this into perspective, most of you do not have a store full of dacs we do!
The unfortunate point of all of this is there is good, there is better and there is the best of these kinds of products.
In this case ingnorance is bliss, if you care about spending less money.
We have the Lumin D2, the T2, the X1 which do represent the good, the better the best You can clearly hear the improvement as you go up the scale.
We are doing this morning a comparision the X1 vs the T+A SDV 3100 and again the sound takes a dramatic improvement in realisim, soundstage size and width, the sound becomes more real and much more musical. It is worth the price, yes if you can afford it and have the system to show you the difference.
As per the OP the T+A piece represents a fascinating opportunity to get a world class preamp that may dramatically improve the overall system’s sound as well as if he prefers the clearner sound of the T+A as a preamp then he can recoup some of his investment by selling the Mcintosh preamp.
When designing a system you can go with what "fits" which can mean anything or you can buy the best that you can.
If you remember the Linn concept which is the sound starts at the source the better the source the better the sound you can create.
Also a digital front end of this calibre means that the OP can continue to grow into this system by eventually moving into even better electronics if he prefers over the Mcintosh amplifiers, which would again he could continue to evolve his sound.
A top of the line front end would not be wasted in the context of the OP’s system, wether he choose DCS, MSB or T+A all of these top of the line front ends will help improve his system more so than a much cheaper front end.
Again we are writing this while doing exactly that same comparison on a $20k amp, a $32k pair of speakers, and just comparing two front ends, a very very good one ,the Lumin and one of the best in the world, the T+A, in the context of our system you can clearly hear the superiority of the better setup and yes it is worth it, however, without having the Lumin, the Formula and the other less expensive digital front ends to compare with you would be happy with one of those if you never experienced the next level you can accheive with a stelar dac such as the T+A.
Try the same comparison with a good car such as a entry level Mustang and the new Corvette does the extra $20-30k make you happier
