The Love of Turntables and The Organization Of An Audio Room

@lewm Thank you for the kind words. Since my son milled me the plinth, as you can imagine, it will never leave me. 

With that being said, I know it can be argued that I could have proud pappa syndrome in this case, but the sound I am achieving has notably exceeded my expectations. 

Is the DP80 significantly better than the DP75 I have owned, and own again?

Is the plinth we built contribute to this excellent performance?

Is it significantly better than the original VPI plinth I had a DP75 in?

Is this Dynavector DV505 noticeably better than the other two I owned?

Is this Wireworld Silver Micro Eclipse tonearm cable outperforming the OEM cables that came with my Dynavector arms?

There is no way for me to answer this with any certainty. There is just no way for me to isolate all the variables in this iteration. 

All I know is this is sounding very nice. Even this final set of no name feet and receivers I am using for the points is providing wonderful results. 

As I listen to this, I have a hard time justifying to a person who is cost conscious that this is not one of the best choices they can make. For a long long time I have been a reluctant user of direct drive tables. I liked my SP 10 MK II and my DP75, but those were exceptions to the rule of how I felt about most direct drive tables. It still may be true. But I will say the DP80 is a champion, and if people ever catch onto them, the price is going to rise significantly. I am glad I got mine. 

A bit crowded. 

The three TT's look great.

Pretty sure if you only had two, you would hanker for another.

I've managed to cull mine down to 2 in the system and a project/spare.

As far as the Dynavector's go, I've had quite a few over the years, I have noticed the pillar bearings are generally not great, but if the arm is balanced correctly this does not seem to matter. Rather than use the counterweight markings, I set the cartridge tracking force to 0, and move the main counterweight until it the arm floats freely, and I can see it moving in the breeze. When you see this you see the beauty of the dual axis system.

The Dynavector arm cables on the early arms 505, 501, 507mk1 are very average - I never use them. The arm cable on the 507mk2 is much better.

The only other problem I've seen are poor quality headshell bayonet fittings. In one of my 501's I had to take the headshell bayonet off and machine the face square so the head shells were stable when tightened.

I am also more in line with @ghdprentice but respect those who want more TTs. I think one of your problems is the many small pieces of furniture. If you want to go all in on multiple TTs, have the furniture that helps with it. I would get rid of the credenza and the couple of short vinyl shelves, and have a long support built. possibly 1-2 rows for records below, on top the TTs. You may even consider putting TTs on top of one another on different levels of floor standing shelves, or have some floating wall mounted shelves.

Fewer furniture items will make for a cleaner look and in the end be more space efficient.

If you are somewhat handy, making some support structure out of hardwood is not that difficult. Or maybe your son can help with it?

I am grateful to have an understanding wife who knows how much I love having a dedicated audio space. That being said, the space is small and I also love having other gadgets on my audio rack, besides turntables. With that in mind, I have always had only one table in my system at a time. I rely on having removable headshells, despite the added mass and etc., so I can indulge my tastes in different sounding multiple cartridges. I would love to have more than one turntable, but it's easier to store a second or third headshell with a mounted cartridge.

When I had the dp80 side by side with sp10 mk2, I preferred the dp80 by a narrow but audible margin. (Both were fully serviced calibrated, recapped, etc. The late Bill Thalmann did the work and also replaced the OEM transistors in the dp80; there are modern equivalents with better reliability.) That led me to sell the Technics, but I subsequently acquired an NOS MK3. I admit my motivation in addition to that of music lover is vintage gadgets.
