I do that already, altogether I have 5 audio inputs going in to my gear, 3 to the mscaler, 1x usb and 2x optical, and 2 directly in to TT2, 2x optical and the dual bnc cables coming from the mscaler, but we won't include them.
My Chrome Crap Audio goes directly into TT2 and, at times I've seen me use the CCA and forget that what I'm listening to is not mscaled.
Anyway, I could be an hour or two into listening and I've seen myself say, this song sounds excellent, my setup is great! and then I realise I've been sitting for the last couple of hours listening to non mscaled music and not missed the mscaler one little bit.
I would of thought that if the inclusion of an mscaler gave huge SQ improvements, then I would of thought that I would easily notice the lack of such huge SQ if the mscaler was removed from the equation, but I don't, which is weird and annoying at the same time.
Now everyone remember, I'm not hating on Chord or Rob and, that all of the Chord DAC's that I've owned have been very good to amazing. Plus I'm thinking about upgrading to another DAC and the ONLY one that I want to upgrade to is Chord's Dave. No Bartok or whatever else for me, I'm only interested in Chord DAC's as I know their dac's sound great.
Maybe what I've been told about the mscaler by various hifi stores is true, in that the mscaler only comes alive when it's connected to a Dave.
Regardless of whether the mscaler is connected to my TT2 or not, I'm still loving my Chord dacs, music from them sounds excellent and I can't dispute that, as they do make the best sounding dacs out there in my opinion.
What I find a bit puzzling is WHY? you bought an MScaler if you can't hear much improvement using it?
Some of the other questions you raise are interesting though, imho.
I also suspect that there are possibly MANY more things involved in making a good dac than just the number of taps employed.
And I too find it VERY annoying when only one important disadvantage is adressed as in the case of the lack of power with certain headphones with DAVE, while still only using a 10 elements DAC in TT2.
I don't like it when companies intentionally strangle a product to fit the intended market.
But unfortunately they do!
In the world of Digital Photography my profession, Canon has been proven quilty of actually hiding useful tech in some models using the same tech.
I hope Chord is not guilty of such marketing strategies at least.
But I also find it a bit surprising that I can get even better SQ from my Qutest HMS combo both by using a battery powered PSU with the Qutest instead of the supplied one. And that BNC cable upgrading is also a very obvious improvement over stock.
On the other hand,I can quite easily hear the advantage of DAVE against the other Chord DACs and many others too for that matter.
But I strongly dislike its price its format and lack of power.
I don't know if the increased transparency of DAVE is because of 20 elements over 10 on all the others?
But I have reasons to believe it may be at least one reason why it is more transparent.
And although DAVINA seems more of a teaser than anything we will see or hear in action any time soon,
Rob has stated here that DAVINA will be a 40 elements unit unless my memory fails me?
That fact and claims made by some competitors, lead me to suspect that the number of elements actually DO MATTER.
I wonder if both the type of and the number of supercaps used also matter?
But to my ears and with the type of music I primarlily listen to ,unamplified ACOUSTIC music and the human voice, the improvement an MScaler adds with the Chord DACS it can be connected to, is VERY obvious both via headphones and speakers to me.
I would NOT have bought one if that had not been the case for me.
On the other hand the old piano I bought for 100€ including home delivery! a few weeks ago at a thrift shop sounds CLEARLY more REAL than any HIFI I have ever heard.
Not even HMS/ DAVE can play back a piano as it really sounds live.
We are simply not there yet.
Rob has, I think, said that DAVINA ultimately will solve that little problem.
But when?
Maybe someone else gets there before him?
