I would think they would do very well with the rest of your components especially with vinyl. Yes, soundstaging is one of CJ's strong suites. I do not agree with Brulee about CJ being too coloured.I have always found CJ equipment to be extremely accurate with most other equipment being too sterile and uninvolving. I have considered buying a pair of 12a's myself...3500 I feel is a good price for a pair of 12a tubed mono-blocks. However, I believe I will hold out for a pair of 8a's or maybe go with one of CJ's new tube amps.
