Mods in Tube players: list in order

Ken just changed out the other 4 opamps and ahs made another significant boost in this true balanced design.
First we changed 2 of the 6 opamps, and now the other 4.
I'm listening to Mississippi Blues cd, the vocals are super realistic, instruments are clearly separated. The bass has power to where i can now only turn the Jdais up just past 9 O'clock. Any more with rattle the dual 7 inch Seas mids in the Thors.
Somehow new higher grade opamps boost the fq's, allowing cleaner higher resolution.
I
'll find out the name of the opamps Ken used.
My next move may be to upgarde these Romlex commercial wires I bought at Lowes for $25. I'd like to look at some silver/copper combo, see if i can get some improvment in the upper hz's.

I think Home Depot has some wire that Lowe's doesn't carry. Check it out.

Well I had the other 4 opamps replced in the 17. That makesa total of 6 changed. My tech guy said the original are $2 opamps, and he used ones that were "la creme de la creme" costing $25/each.
I did notice a significant gain as the first 2 were changed, these were the 2 most important I believe. Now the 4 behind the 2 manis were changed and sure enough added benifits in the soundstage can be heard.
But as I say the complete 6 new opamps have made vocals seem cleaner, much more live like, bass is deeper. Power has been increased, as i play the Mississippi Blues cd, the drums now rattle the midwoofers and this just at 10 o clock vol.
At present the amp is the weak link in my system. The Thors have more potential, the Cayin has more potential.
My tech guy does not feel its necessary to change the caps to Mundorff, as the stock caps are already superior quality.
I will try a quad of sovteks to see if they beat the stocks.

From my experience I would say the following order applies to most any mod, not just CD players:

(1) clock, although a very expensive mod, it has the potential to make the most improvement in CD players
(2) power supply, especially for switching types in any digital circuit, but this can be tricky for any tubed circuits
(3) analogue section, including op-amps and coupling caps, this is a 50-50 with the power supply but will have a bigger impact if the power supply is upgraded also
(4) general resonance/vibration control, I consider this a mod although other would say tweak, in any case it does work and is cheap to do, but not necessarily easy to do right
(5) internal wiring and connectors, if you're in there and you want to be a completest this can be done, but it should always be done if any of the connectors are cheap nickle.

Enjoy,
Bob
