speaker cable and interconnect confusion

I've been doing my homework to figure out what type of speaker cable I want to purchase to use with my HH Scott LK-72 vintage tube amp and Altec Lansing 604E Super Duplex vintage speakers. I figured I'd try Blue Jean Cables Belden 5T00UP cables, figuring they would go well with my vintage set-up. Since Belden cables are the industry standard in many broadcasting and recording studios, which is where the Altec Lansing were used the most, they would be a good match. Esoteric and expensive cables seemed to be wrong for this type of set-up, especially after reading the "Snake Oil" article on cable manufacturers. After I made my decision, I came across a chart that said I should go with 18 AWG cables, since my amp's speaker impedance is 16 ohms and the length of each cable is only about 7-8 ft. Now I'm confused. What would be my best option with amp/speaker set-up?:confused:

Interconnect confusion

I've been reading up on myths and facts on interconnects and I'm wondering if I should replace my Audioquest Copperhead and Coral/CQ cables with Blue Jean Cables LC-1's. I use the Coral/CQ with my turntable and I just read a lower capacitance cable is crucial when hooking up a turntable. I use the Copperhead with my California Audio Lab Aria MKIII and I wonder if I should swap cables with it too. I read somewhere that the Audioquest cables have a very high capacitance. Any suggestions?

Blue Jeans Cables is not a bad choice to connect your Altec Lansings to your tube amp. 18 AWG is fine, though there's nothing wrong with getting thicker cables. If I were you, I'd just get a spool of 16 gauge Amazon Basics lamp cord. There will be absolutely no audible benefit to using anything more expensive.

Re: turntable interconnects, is there a problem with the sound that you're hoping to correct? If not, then don't fix something that isn't broken. But if so, then the brand of cables you're using probably has the least amount of influence on the problem sound you're getting. You should first consider having that vintage tube amp rebuilt if it hasn't seen a rebuild in the past couple of decades.

For years, that vinaage sound that everyone craves, particularly with those vintage components you mention was obtained with fairly generic IC's (well constructed and well shielded but not expensive) and 16 gauge lamp cord.

What you have isn't bad but you certainly paid a steep price for peace of mind.

As far as my amp goes, I had it restored by Craig at nosvalves.com years ago when I first bought it. There isn't any huge problem with the sounds I'm getting from my CD player and turntable, I just thought it might be cheap to try out the lower capacitance LC-1 cables at some point. I probably won't end up buying them unless the other upgrades to my turntable aren't enough to convince me my system is at it's best for my budget. I think I'll try out the Blue Jean Cables 5T00PU cables (unterminated), they sound like the best deal. I'm not necessarily looking for a completely vintage sound, I just want the best sound possible from my Music hall 5.1 table and my tube CD player at a price point that I can deal with. But thanks for your advice.

Apparently, your turntable has RCA jacks to allow owners to use different interconnect cables between the turntable and their receiver, amp, or preamp. Did Music Hall supply interconnect cables with your turntable? If so, I'd guess they were no longer than about 4 feet. Use them.

The signal levels put out by moving magnet pick up cartridges are very low, roughly 5 mV. As a result, besides adequate shielding, the most important feature of turntable interconnects is that they be no longer than 4 feet. Longer cables can have enough capacitance to significantly filter out some of the higher audio frequencies. Choosing so called high performance cables will not improve the sound over the interconnects that Music Hall provided.

Older turntables always came with these cables hardwired in place. That was the best way to prevent owners from "fixing something that wasn't broken" :D.

If the location of your turntable requires using interconnects longer than what Music Hall provided, you have two choices. Rearrange your gear, or add a stand-alone phono preamp between the turntable and your amp. Use the Music Hall interconnect from the turntable to the phono preamp, and what ever interconnect you like from the phono preamp to your amp. The phono preamp boosts the output from about 5 mV (phono level) to at least 100 mV (line level). At line level, problems from longer interconnects go away. If you do this, you must use a different pair of input jacks on the back of your amp, not the phono inputs.

Your CD player puts out line level signals, so it is not subject to the same problem as a turntable. Different interconnects for line level signals, despite what you may have been led to believe, are unlikely to make an audible difference.

All those fancy cables, even the so called skin effect ones - will be just as Good as some RadioShack speaker wire.
It is nice, when you can save some money!

The LC1 cables are easily my favorite interconnects right now and have been for years. I use them for nearly all my analog connections. I use the 4S11 wire for my speakers but I've used the 5000UE before in other systems and it works great too.
