Thanks for your responses, all most helpful.
Goatwuss, your question regarding "problems" with the sound of my Hovland is most salient. It is a great preamp falling sonically somewhere between a Jadis JP 80 MC and an ARC Ref 3. As French_fries has noted, its noise-floor has currently become an issue since I began using YG speakers whose accuracy, neutrality and transparency I now find the benchmark to which I want my other components to adhere.
For me it has become the reverse Ivor Tiefenbrun syndrome. To my surprise I have found that the extraordinary accuracy of YG speakers is best complemented by equally accurate components rather than "compensatory" romantic alternatives.
Not that I mind "euphonics", but think I'm moving beyond that.
But I do intend to add more digital sources to my system.
The Boulder 1012 preamp with integral phono stage and DAC also interests me and I would be appreciative of opinions of that unit as well.
For the record, I am now running YG Anat Reference II Studios which have surely ignited this not unwelcome dilemma.
