Elliott (and anyone else), I am not recommending used equipment of any kind for this novice. I may suggest the idea to her, but I doubt she’d be interested. If I suggest a specific used item for her to buy, I’d then feel responsible if a problem arose. Since I am now 7600 air miles from Tokyo, that would be frustrating. She’s best off with new gear she can buy from a local dealer, with a warranty. I know you mean well, and I thank you for your efforts.
Here’s a question: self powered and maybe also wireless speakers are a great space saving idea. The question is whether such speakers can be driven adequately by the output of a phono built into a cheap TT or an inexpensive outboard phono stage, like the iFi Zen, which I did see on sale in Tokyo.
