Which Power Cords: I Need Some Informed Guidance

Some ideas below in your stated price range (mostly).

1. I would contact The Cable Company and ask what they recommend for your gear in that range.

2. For your Cambridge 840C I would check out the JPS Labs Digital AC power cord and the Shunyata Research Diamondback Platinum and Taipan Helix VX (the latter a very good deal right now on close out, but still over your stated budget) - I can vouch that the Shunyata cords sound very good with Cambridge Audio CD players

3. For your Krell, I would suggest you check out the Analysis Plus Power Oval 10 and Power Oval 2, the JPS Labs's THE POWER AC +, VH Audio Flavor 4™ Power Cables
with the upgraded Furutech connectors and the Shunyata Research Copperhead and Taipan Helix Alpha (also a very good deal right now on close out, but also over your stated budget)

4. Once you get your new power cables, you may want to upgrade or downgrade your power conditioner. Try plugging your gear directly into the wall socket and see if it sounds "better" or "worse" than routed trough your conditioner. If you live in a single family residence with decent wiring, chances are your system will sound better with no conditioner at all. If this is the case, and you still need a power bar for multiple AC connections, I suggest you check out this low cost but excellent solution:

If you are an apartment/condo dweller, more intensive power conditioning MAY BE necessary. Trick in this case is to clean power up a bit without sterilizing it (i.e. clipping musical transients). This may cost a lot of money to get truly transparent filtering - if such a thing exists at all.

Good luck.

Since when do we listen to cables based on what color they are? One of the more ridiculous statements I've heard here on the Gon.

Neutron,
Wow! Deja Vu. Are you me? We almost have identical electronics (minus the Cambridge and MIT) and the types of music. Scary!
I was going to post couple P/C that I didn't like, but, to my experience, what I didn't like yesterday, didn't mean I don't like them today. Since I spend a lot of time playing (mix /match) with my system and friends', it's good to keep them all. Some of them sound flat in my system but they sound very detail and punchy in my buddy's or with diff combination of ICs.
Sorry, I didn't mean to give you a run around, but that's my .02. Just feel confident to buy what you can afford and the most popular ones. (You can always resell them here at the A'gon for any reason.) I have not seen any of P/C that is awfully bad except for my DIY from HomeDepot ones.
Don't forget to keep us posted. I'll be watching your posts closely since I have the SF GP Home series (front port) too. If color is matter, mine is in Cheery wood, lol.
As Tom92602 says, P/Cs make HUGE diff. and I hope others may shy you a brighter light.
Good lcuk,

neutron;

here are my thoughts;

1.try Mapleshade cords.it is almost as good as Argento MR ,which in my opinion,are amongst the best around.and it cost so little it is just increadible!!!!

2.you should try the mapleshade IC and sp cables too..again unbelievable value for money.

3.you MUST cook your cables with the Audiodharma cable cooker.I have one for myself but you could easily find a dealer who could cook it for you for a small fees.anyone I know who has had their cables cook will not listen to an uncook cable again.

4.finally all cables should be treated by deoxit gold. it just sound better.

cheers
