Should I got full tubes or stick with hybrid amps?

Sorry I didn't get back sooner.

Assuming that the sound of the tubes in a "buffer" is similar to what they would be like in the gain stage of an amplifier the GE 5751's were a good reasonably priced pick if you were aiming for more clarity/detail over typical 12ax7's (probably what I would have tried).

I would also take a look @ the Sovtek 12ax7LPS if your goal is to squeeze more detail out of the 1501.

Another cheap/free experiment would be to support the 1501 with "hard" footers to see if doing so increases detail enough without robbing fullness/richness too much.

Perhaps something around the home used in a 3-point position?

I've owned various purpose made cones and ball bearing footers, but have also experimented with things as simple as bull nosed lug nuts and small ceramic ramekins.

I don't know anything about footers or isolation.  Do they really impact sound that much? Even in an amplifier?  

Yes, they have for me...

Hard cones/ball bearings brighten up the sound VS soft footers (less/tighter bass/more detail), but they are a mixed bag.

Just rec'd trying something cheap/free as it seems to me that you like the Jolida, but just want a bit more detail.

I ended up (years ago) using the stock footers on my gear in combination with specialty shelves in my rack for the source components (TT/CD), but did try various soft/hard footers with power amps/ preamps/phono preamps & dacs and...

Yes, the footers did change the sound and my electronics are not even located in the listening room (see my system link/details) so airborne vibration was not really a part of the equation.

Even a hard wood cutting board placed under the amp (forgot to mention that one) may make enough difference in adding detail, depending on what the amp is resting on now.

It's actually on a glass top desk. :-)

What does everyone think about the PrimaLuna Evo 100?
