Cable auditions - Hard Work?


Does anyone find it to be "hard work" to audition cables? I find that I have to be 'fresh' before I can begin to listen to cables. After I begin, I can only listen, with the intensity needed, for a period of about an hour.

As I do A/B comparisons, it sometimes seems, my impressions change as I listen. Sometimes the differences are so small or subtle, that I question if I'm hearing a difference at all. Have I lost it?

How do you folks do your cable auditions? I'd really like to know.

Thanks

You guys tell me about the equipment:
TRL Marantz SA-14
First Sound Presence delux MkII
Krell FPB400cx
Tyler Acoustics Linbrook Signature (one piece)
Room is treated with 16 Tube traps, of various sizes, placed symetrically around the 13x18 room.

I think the equipmet is revealing enough. What do you think?
Thanks for everyone's help.

Not a big fan of Krell FPB400cx. Have you tried Jeff Rowland?
How about some tube amps?
TVAD - where did your post go???!!!! I saw it here last night, but haven't had a chance to post. YIKES!!!

Hi Tvad

Glad to see you back. :-)
1. It seems resolving to me too.
2. I have never investigated power conditioning. Not really familiar with it or its benefits.
3. Just thinking I might be missing something. I think i'm coming down with "the disease" Adiophilia Nervosa! :( I'm trying my best to keep perspective though. Plus I don't hear obvious differences in the cables I've switched in and out. That's about it.

Thanks for getting back.
BTW - how did you delete a post?
