Mgreene,
NO offense meant, but I think you should back off on Raul's full function preamp. I have heard it, seen it, felt it, over a year an a half ago and I understand that there have been some improvements made as Raul and Jose keep working on it. It is an extremely viable product and I have no hesitation to say that it is probably one of the best, if not the best, SS units available today. I don't blame Raul one bit for not wanting to give you or anyone else what he and Jose have been working hard on for many years. There are many other areas in this hobby that I disagree with Raul on, but this is not one of them.
And I agree with Raul's and Audiofeil's assessments of the 834P. I owned one, did all the mods, rolled in some tubes, etc. I did sound better, but still kind of warm and fuzzy. But let's be fair, the 834P is at best an entry level phono stage. So I would say no, putting a set of Bent Mu stepups in front of it is not going to change how the EAR sounds. But these are some of the best stepups around so they can be used with many phono stages.
