[Premium-Rx] Best Premium Receiver?

Tue Nov 6 21:07:05 EST 2007

Bravo, Les

Yes I too stopped collecting and sold all the receivers but the WJ's and the
7800. 

Guess what's next on the chopping block? (hint: it's the one that does not
perform as well. Maybe some would say that it's a dog or maybe biased
nonsense. We all know where the troll lives here)

I long ago gave up the "search" for the "Holy Grail" of receivers, after 
over 130 vintage and solid state receivers, I am convinced as are many 
others that it doesn't exist.

Yeah, this one has this and that one has that and the notch is better and 
the synchronous detector blows them all out of the water, etc.

I have spent far too much money in a foolish pursuit, as have many others.

I now listen to what I want when I can and don't worry about what so and so 
says about the Super Cohamhalliicomyasken receiver.

Enjoy what you have and forget about an endless pursuit, save the money and 
take your wife/significant other on a nice vacation.
