importance of phono cartridge

Well a big thanks to Albert I SEE THE LIGHT NOW.I'll need to take the all Purist Audio cable route as my money will permit me too.
I should have borrowed some top of the line speaker cables while I was at it from Alberts closet as well.I know I will have serious withdrawl's when I return the cable,But IRS owes me next year so maybe I can take the plunge then.
Having Dominous as a phono cable must do so much to a turntable that I just could not even imagine.

I'm checking into having Purist build a cable for my Cosmos. The motor is DC, so I want to have the imbilical cord running between the power supply and the TT upgraded from stock.

A couple of people have mentioned that upgrading that cord really helped. So far I have yet to be disappointed by Purist cables, but they won't add back what the cartridge didn't get from the LP.

Nrchy, you are quite right; "won't add back what the cartridge didn't get from the LP"

However, with regard to the original post, I do believe in giving any cartridge the opportunity to 'be all that it can be,' which brings us back to the TT and TA as the place to put the lion's share of one's available resources first, and upgrading cartridge, cables, phono preamp, as money permits.

Once again, Raul does not directly answer the straightforward question posed to him.

Dear Larry: How can any one state precisely an answer to a " wide open " question?

+++++ " will a $1600 TT/tonearm with a high end cartridge sound better than a $5000 TT/tonearm with a average cartridge ? " +++++

Example of an answer, YES: Technics SP10 MK2 with a Moerch DP6 ( second hand ) and a XV-1 Dynavector cartridge. This combination can beat a high price TT/tonearm with a cheap cartridge.

But all these tell us nothing at all, but that to have a good quality sound reproduction we need to have a good sinergy ( match ) between each one of the links in the very complex audio system chain.
The name of the game is: SINERGY .

Regards and enjoy the music.
Raul.
