Audio aero capitol reference cd - upgrade


My audio aero capitol reference has loud bass which is not tight & lacks resolution compared to my Marantz SA11S1.

I hope a capitol SE upgrade will help

What make the major difference -

*capacitors ( teflon V caps r easly avalable for $100)

*Cryo" tubes

How much does the Official upgrade cost?

inputs welcome & will b helpful for me

Thanx in advance

Don't spend money upgrading (modifying)the Capitol. If it doesn't work well for you now as is, maybe it's not the player for your system. Tube rolling should be enough. Sounds like it's not a good match with your other gear. The funds you invest in an upgrade will be lost in total should you ever decide to sell.
thanx guys

but i like the HF & mids , expecially the mid transparency of capitol.

Upgrade kit costs $700 (for capacitos ,vibration absorbers for the capacitors & cryo tubes & )

Capacitors alone is avalable for $100

want to which component makes the major improvement

cryo tubes or the capacitors ?
i got a pair capacitors for $100,
a pair of cryo tubes for $75.

vibration absorbers for the capacitors ?
The upgrade to SE thats done by Audio Aero was worth the money for me, Bass and resolution will both be improved.
