Yes, I was basically running the setup I was describing. I had a restored fisher 500c that was powering the stax, but it has since been put to other duties in the house. I was deciding my next amp move with the stax when I came across a fisher 400 in need of a restore. I was generally happy with the sound I was getting with the 500c and the energizer, but I've never had any long term experience with anything other than the srd7sb. I was going to build an exstata, but I changed my mind on that.
So this is what really got me thinking about the sb units. I'm wondering if anyone has any thoughts about the ultimate potential of these. Or if they will always come up short in a specific area. Is it a situation that no matter what you feed into it, it will never have the bass impact of an amp? is the sb unit really just a low end piece on the ladder that should be used as a stepping stone?
I say all of this like I dislike the sb unit, and that is not the case. I am just interested in its limitations, or advantages I suppose. I have always understood that if you had a great amp feeding the sb, then the quality of said amp is what you got in return. But then again, every time I spoke of using an sb unit, people would always say that I should get a standard srd7.
