have you ever bought stereo without listening first

It's almost impossible to audition a phono cartridge in a meaningful way before you pay for it, in my experience. All the other components I have 'bought' without hearing first have had a reasonable return policy. Luckily, few have had to be returned because, like many others have said, I research the hell out of stuff.

PS. I have been to Audio Connections many times and I respect their experience and opinions. Don't worry @Iobinero, if your not delighted; John will make it right.
