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

Hi Sm2727

standing wave problem, yes i changed my room , its sounding fantastic now.

Its sounding so good that i was delaying the upgrade.

Now On the process of upgrading with - VH audio V caps 0.1u 600V and sylvania cryod tubes. yes $250

By the way did you go for the 1% or the 5% V caps

thanx
The Cap reference does not have boomy bass by itself.
Here is a very simple trick to find out if your player is suffering from standing wave "bass boom":
Play a track with heavy bass (not a single-note solo, you want the bass notes to go all the way from top to bottom) and walk around the room with your ears at the player's height.
Hear for bass boom where your player is located. If boominess is present, keep walking, find a spot with no boominess, place the player exactly in that spot.
Bingo!
P.S. Sometimes a higher or lower shelf will get rid of standing waves, because room modes propagate in three axis.
Masilu,
Upgrading caps to VCAP CuTF was major improvement of resolution and transparency for me in my AA Cap MKII. But after changing tubes I have lost bass impact and dynamics. Have you observed any changes after changing tubes from stock Phillips to cryo Sylvanias?
