I had the Bridge connected to my integrated (Yamaha A-S2100) initially, but knew I could use it as a preamp too, so took the integrated out and hooked it up to my back up amp, NuForce STA200. This took the SQ up a notch which was surprising, to say the least. $499 amp vs. $3500 integrated.
As a preamp, the detail & clarity was much better, wider soundstage too. The Yamaha is much warmer sounding that the NuForce, which usually isn’t a problem/issue but it was just too much for my taste. My Spendor A4s are on the warm side of neutral, but this was never an issue when I was using the Mytek Liberty with the Yamaha. Strange is all I can say. I assumed both Mytek Dacs would have the same signature.
The STA200 did lack in the bottom end though, compared to the Yamaha, so I found a good deal on a used Wyred4Sound ST-1000 MKII amp, and the bottom end is back to where I like it! The W4S is also much more quiet than the NuForce and Yamaha (and more powerful too).
Really loving the Bridge w/ W4S combo, which on paper, most would assume to be too clinical sounding, but it’s a great match with the Spendors.
Anyways - I found the right streaming DAC for me, but also made some unexpected changes along the way too. That’s hardly a surprise for those of you who know me :)
