I figured some tracing and tweeking in the phono loop was in order. Its good to know that the noise I'm hearing should be expected. It's not really an issue when listening as I don't normally push the volume that hard. Which even makes that little blip at the end of the volume range a non-issue. I will deox again though, I know its there so it bugs me.The education on the wiring was very helpful. Some of its beyond me. Think liberal arts campus versus engineering campus. But, I do get the points about matching wiring, cables, interconnects throughout the system.
One thing that was a big aha with the Marantz was improvements in the phone sections. Much better. It is really pointing out flaws in some bad vinyl I have and groove damaged that went unnoticed before is quite clear. Helps me sort the good vinyl from the bad. But if the vinyl is good and clean......ah....very very nice. Once I get the bugs worked out of the wiring chain I think dialing in the carts algnment again is going to be rewarding.

I think I must have passed some kind of milestone with my Advents. I have a line on a pair of nice clean New Advents, and I'm probably going to pass on them in favor of what I already have. This after looking for a nice pair for a coup;e of years.
One of the nice things is that I am really pleased with the sound and performance with the Advents I have. And, really didn't have to do much to get them there. It was really nice replacing those caps in the crossover. Now, looking inside the Marantz is a bit of a different story. Just a bit more intimidating wiring wise!I'm content for now, but will be on the look out for some nice walnut cabinets with components that can be brought to life. Then I will be searching your post and doing the total upgrade. Braces, terminal post, internal wiring, etc.... For me, its always good to have something to look forward to with a goal in mind.
At some point if I can score a spare tonearm for the dual may try a rewiring on the arm. That's the one complaint of the Dual is that the tonearm is what it is.
I've owned quite a few Dual's over the years, and I found the tonearm to be pretty good, clip in headshell and all. It gets a lot of flack, but mostly from folks who don't understand the design. The aluminum/plastic construction is really pretty well damped because of internal friction between the various parts that are clamped, not bonded, together; so resonances in the arm don't editorialize as some "better" arms do. Also, the spring system for arm weighting works well and is not sensitive to attitude (although I always checked mine with a Shure gauge). Dual used to demo that by having their TT at really extreme angles, or even upside down, playing happily.
The tracking on my Dual is superior. I like the idea of checking the tracking weight. Think I'll have to invest in a scale. I just wish the wiring were more accessible so that a rewire would not be such a hassle. But, in the long run I'm not really sure if a rewire would resulted in a measurable gain. This may be an area where the adage "If its not broke don't fix it" applies.
If you're talking about rewiring the tone arm, don't!!! A) it's not easy and you risk trahing the TT; and B) it won't gain you anything audible. I'm obviously not into exotic wires and cables, and I believe that this is one area where measurements do tell the story.IMHO it's very much a case of "if it ain't broke don't fix it".
I take that as sage advice. I was more serious about thinking about taking that on before I bought my current cartridge. I was having connection, grounding and loosing channel problems. Mounted new cartridge and that's all gone completely. Certainly points to a faulty or failing cartridge.
Decca arms had plastic in them too! I agree that it is not a sing of low quality. Although I have gone on to lofter tables, I still like the Duals and recomend them to friends. Duals are music lovers tables.
