thats like asking which of your children is the prettiest!
I like all three of my current Garrards, for different reasons.
The SP25IV is the only working one. Thats gotta be good for something! It has all the charm of a housebrick, but is also as reliable as one
The SL 95B is the most "manly" looking - in a very Burt Reynolds, hairy-chested playboy kind of way. Its in a heavy teak plinth and is badged as a Bell (!) so its a bit of a barstard child, but I still admire it.
My Zero 100 appeals to the engineer geek in me. It is clearly a product of late 60s English engineering - delicate, often broken, conceptually sound but flawed in execution. Emotionally, you just want to pull on a safari suit and trot off to Carnaby Street every time you see it. I wouldn't mind betting that, once I do get it going, it only plays the Beatles, rejecting any vinyl pressed outside the UK.
I just bought an old Akai deck. Its about as emotionally engaging as a fridge. And thats without plugging it in.
