I have owned a Linn table back in the late 70s and found it to be very good, although the suspension is far to compliant for my tastes as well as was most of the Thorens at the time. Overall the Linn product has not evolved much,but remains good value in the used market. But one has to be careful with Linn as they are delicate,and I have found them to be maintenance hogs. But nonetheless they do have very good sonics when paired with the right phono cartridge.
As far as B&O goes I am not a fan of B&O aside from the glitz and glamour cosmetics their is little to endure. B&0 tables means your stuck with using B&O phono cartridges only. B&O no longer makes these cartridges,but a private company has sprung up that makes B&O phono cartridges. Once one sees the inside of one of these tables and the parts quality there it is disheartening to say the least.Plus at this point in time parts for these tables are drying up quickly as B&O has withdrawn their service network and dealers. All B&O is now an in house affair with company based stores. And no one in these stores have a clue as to analog needs. My last experience with a B&O was the Beogram RX and that was one of the poorest excuses for a turntable I have seen, except for some of the B.I.C. tables of the late 70s.
I know their are some loyal B&O users out there and will probably be gored on this. If it works for you then, fine,but much better to be had and for gods sake don't spend more that $150.00 on one and when it breaks, as it will, just toss it,not worth the greif and aggravation of servicing.
