Doing a search I couldn't see if this had been discussed recently, but are any of you using high quality active filters in your systems, and if so which?

I've been looking at the likes of DEQX but would prefer to not subject my lovely forty year old vinyl collection to a rather crude A-D process unless someone is going to tell me it's transparent. I know Widget is using one. How is it and what's the rest of the setup?

For analogue options, what's out there that's better than the Bryston 10b (which I thought sounded godawful)? Is there anyone out there making custom tube units that allow for baffle step and other variables? Also, when going active, are you leaving a passive cap in circuit to protect compression drivers from any unforeseen switch on thumps? Or running correction and attenuation filters passively as the DD66000 does when bi-amped?

Sorry for all the questions but I just haven't been able to find anything that suits.
