effect of tubes in cd players

I had the opamps changed in the Cayin 15 to wonderful effects. , the 15 which offers ss and tube outs. The bass is a tiny bit more pronouned through the ss, but the mids and highs are superior in the tube out. So thats how I listen.
My Cayin 17 offers only tube and am in the process of making my final tweak, changing the caps. I'll post a note on the results.
Makes sense to me that cahnging the cheap stock caps with mundork M series (not their best , not the cheapest) would affect the sound, as the caps is the very last stage that the sound passes before it exits the cdp.

My Vincent CD-S6 MK is a tube hybrid.
In comparison with a Denon 2900 and Sony 900v, the Vincent is more transparent, open, accurate, pace without being harsh. So not all tube cdp are warmer.

Not a hard and fast rule, but something to consider.
Your Mileage (a/k/a hearing) May Vary

This type of dual output CDP is really the only way to discern the differences between the two types.

The differences you are hearing are more to the particular implementation of the tube or ss output stage. Both tube and ss CDPs are all over the place sonically. Difficult to generalize, and the same applies to results obtained with a dual output CDPs.

In a dual output player, it is highly likely, neither output type is fully optimized. I would rather have a designer stick with his opinion what sound good and accomplish his goals good as possible, doesn't matter which design.
