Digital Room Correction: Where in the chain?

Use the convolution feature within Roon. I agree, it's best to avoid an additional AD/DA conversion 

I’d been using digital room correction since the mid-90’s. After Denis Doyle setup my first Sigtech, I was sold ever since. I also used two units of Z-System rpd-1 in different systems which help me learn much about digital eq. After 4 Sigtechs and 5 DEQXs, all still in use, I’ve learn a little about DSP room correction.

Best place to employ DSP correction is immediately before my DAC. I found that build-in DACs in Sigtech and DEQX were the weakest link. Another observation I’d learn in my systems were the degradations with Pre-amps. However my limited exposure to high end preamps were a tweaked SF Line 3 and a Boulder. But my personal preference is to go direct DAC to amp in the name of transparency. With the right DAC, I have yet to experience problems with dynamics and drive.

Regarding A to D, I’ll go as far as stating that Paul McGowan once said at 24/96, one can hardly detect a difference and I generally concur. I still have a perfectly good unit of Wadia 17 that I use in my living room system that max at 24/48. Through DEQX, terminator, my Karma’s still sings out beautifully. And as far as digital correction sounds thin, I would recoin it as sounding too accurate. One can always bump up the mids a half dB or anywhere to tailor the sound to your liking.

And finally, DSP is the only way I can integrate multiple subs and time their arrival/phase perfectly with the mains. And the end result is true full range, transparent, holographic, and yet musical recreation of each recordings, and sometimes better.
