Lots of comments mentioning Marantz as overrated, but like every brand you have to be careful, as it varies with each model. For example, I have a vintage Marantz 1060 int amp, a modern SR-5001 receiver, and an SR-8002. The sound from the 1060 is everything I expect from a good amplifier, plus more, and it's phono stage is one of the best I have heard. As for the SR's they do a great job for HT duty, which is their main use in my house. For music the 5001 is very good, but not close to the vintage 1060. Now, the 8002 is a great receiver not only for HT, but when you turn off all it's circuitry (using Source Direct Mode) it becomes a wonderful amp that let's you enjoy music, much better than the 1060. Now, in all fairness to those who think Marantz is overrated, I find that their pricing is high, and you can find same or better brands/models for the same price; reason why I bought my modern Marantz gear refurbished, and saved lots of $$$.
Overrated Vintage - Most Pio's and many Sansui's (sometimes price for these two are ridiculous)
Underrated Vintage - Creek, Rotel, Yamaha, and some HK's (you can find bargains on these)
I know this is not about TT's, but I find the Pioneer PL-518 a very underrated TT that can be found at bargain prices.
