I am looking to upgrade my 2 channel set. Giving lots of thought to Cary slp05. Wondering if any of you have experience with this pre and could make comparisons to other pre that you might have tried before or after. Since slp05 its tube i would be interested in hearing from those who might have had SS pre and then moved to tube or visa versa. I have wyred4sound 500x7 amp and Monitor Audio pl300 speakers.
