Plinth ideas for DENON PD-80 DD turntable

I have 2 1000W step/down/up transformers — and never use them. No need. I live in the US and most products — Asian, British, European — make US versions because the market is so large. At present I need only one, for my DP80, and it can be very small: more convenient, smaller than my SUT. The only other time I recall that I needed a big transformer was many years ago: a 100V Luxman tube integrated, never imported here.

If I lived overseas, however, it would be as essential to a good audio system as an amplifier. I was planning to live elsewhere, and acquired a whole collection for that purpose, maybe 20 in all, from very big to small. But sadly that relocation didn’t happen. Though born and raised here, my country, as it is now, doesn’t feel like home.

I wish someone can spread the light on step down transformers subject. 
I've been using cheap and small (made in china) before, but upgraded to the big and heavy local monsters long time ago. I use powerful stepdown transformers, because i connect at least 2 turntables to each stepdown device and i want to be abble to connect even 4 turntables to ONE stepdown trans if needed. 

The majorty of step-down transformers on the market are "auto-transformers" according to their internal construction, i don't know if the term "auto-transformers" is what you use in english. 

But i'm curious why another principle is better (especially for the amplifiers)? As the oppisite to auto-transformers there are different ones with "galvanic isolation". 

"Unlike the auto-transformer, the transformer provides galvanic isolation of the load circuit from the mains. The transformer acts as a filter for impulsive noise arising in the primary network."  

Personally i'd like my stepdown auto-transformers to be a bit quieter, but i think for a turntable stable vontage is much more important. I don't use any power conditioners in my system. 

@pbnaudio thanks Peter. BTW: how do you lubricate DP80 motor?

The bottom bearing "holding" plate comes off by removing 3 screws, so its pretty easy.

What lubricant do you suggest, Peter?

Chakster from the text you quote, it seems that the new product is a “real transformer“ in that it has a primary and a secondary that are discrete from each other. This provides the mentioned galvanic isolation. What you have been using sounds like an autoformer. An autoformer has certain advantages over a transformer in some applications, but probably not for simply stepping down the voltage. 

I use a 50 W step down transformer that I purchased on eBay it is conveniently small. I have one each for my L07D and for my Dp80. Even 50 W is overkill.

@lewm don’t forget that you stepdown from 110/117 to 100v, but i must stepdown from 220/240 to 100v like everyone in Europe.

From what i’ve read the stepdown device must be at least 3 times higher in wattage compared to the actual source (turntable). For the amps the power of stepdown trans definitely must be much higher as far as i know.

I have no problem with mine, each one is 1000w, but as i said i use just one trans for everything japanese and another trans for everything american. I can connect 2-5 devices to each stepdown trans.

I’ve been using a cheap 30w max "super" stepdown autoformer before (it looks like power adapter), but the price for those chinese stepdown devices was nearly the same compared to 10-20 times more powerful local made autoformers people using here for japanese and american audio electronics. So i went for the powerful, the equal autoformers made in USA cost $500 (local made cost under $100).

Japanese stepdown devices like Toyozumi CD240 (or KD1000) are also autoformers and cost 3 times higher. They are very popular here.

But seems like real transformer with galvanic isolation is always better for critical audio devices, especially for amps. And safer for the user.

P.S. I know nothing about technical aspect of the step down transformers and about impact on the audio, i believe it is far more important for the amps than for the turntables. I'd like to have one stepdown for everything (universal), not many different stepdown devices.
