Upgrade Hint 6?


My Parasound Hint 6 sounds amazing but I suffer from the same obsession that many of you do.  How far up the Schiit DAC food chain would I need to go to get an appreciable improvement in sound?

Unfortunately the Topping DX7 Pro employs op amps
So... it also measures nearly as well as the latest Benchmark and better than some Chords and Myteks.

There are many levels of Op-amp quality and the best ones are competitive with top-shelf discrete circuitry. 
Op amps are cheaper than discrete circuits for a reason...

Does a violin measure as well as the latest Benchmark model? I’ve had components that measured amazingly well, and they also sounded completely mediocre.

Two amps that I once owned measured really well and the cheap one gave sibilance and loose tubby bass while the other one, in the exactly same system with the same tracks, did not.
