AES Six Pacs

No, I believe the newer models do offer more power: I sent my older sixpacs in to Cary for the Jensen upgrade and was advised that different transformers were available bumping the power up. After I received them back with the jensen caps and larger transformers, they sounded vastly superior to the original design... Night and day if you will!

I have also found 6CA7 output tubes to be great in the sixpacs, they are much cleaner at the frequency extremes than el34's.

I had these in my system a long time ago, and wasn't super thrilled with them. A little flat, pretty rounded around the edges; definitely not the sound I expected.

How much did the Jensen cap and better transformer upgrade run?

Thanks for the clarification on the updates/upgrades. I would definitely want a pair with the beefier trans and Jensen caps.

I'm probably comparing apples to oranges here, but I'm wondering how they would compare with the Cary CAD120s?
