Seems to be a bit of negativity around the idsd here which I find odd.
Having owned the idsd micro, idsd micro BL and mojo (twice) I can honestly say that the black label and mojo are on par to my ears for sound quality.
The original idsd was a bit lifeless however the black, while on paper people claim minor changes, is tuned with a much smoother warmer tuning.
The mojo and idsd sound different to be sure. But one sounding better than the other I would hesitate to claim. And I am one of the mojos biggest advocates.
If I could get the air, stage and bass of the idsd with the mids from the mojo I would be stoked.
Well you can I suppose to some extent as you can use mojo into the idsd. But it's not quite the same.
On a budget/value for money take it's hard to pass up:
DAC/amp
Odac/objective amp
Modi(of your choice)/vali2/magni)
Idsd black
Mojo
Open cans:
Kiss Porta Pro (everyone should have one)
Ath r70x
Hd700(price at the moment is crazy, though I am not a fan of the tuning personally)
Hd600/650 with crazy sales of late
Closed cans
harder on a budget as there seems to be cheap average close cans or crazy expensive ones)
Ath M50x
Until last year mad dog 3.2 or Alpha dogs were on my recommendation lists
