Anyone can tell me the cartridge shown here?

Looks like a Linn Basic MM, a low end Audio Technica. At the very least you should probably replace the stylus (which can be done apparently with an AT stylus, but it might be a bit tricky). Better yet, just order a new AT 120E which is a much better cartridge for $59 from garage-a-records.

Josep: While the AT95E stylus will fit the Basik body, it is not an "exact" fit (you can do a websearch to verify this). As such, considering the expense involved for the AT 120E which is a superior cartridge to both the Basik and a brand new AT95, buying an AT95 replacement stylus for $25 or $30 for the Basik does not, in my opinion, make much sense. I would doubt very much that the 120 Stylus would fit the Basik body. Buy the 120E, and, as Doug Deacon says above, have somebody who knows what they are doing install it, or, alternatively, as xiekitchen says, go with a Rega cartridge, and once again, have a professional install it properly.
