RE. QUICKIE: ALKALINES VS NICADS

[coca]

I ordered a quickie kit a few days ago and was wondering if there is a sonic difference in the quickie when using nicads or akalines? The reason I asked, is because I once had a headamp for a moving coil cartage that ran off batteries, and it sounded better when I used akaline batteries comparied to nicads.

Interesting on the sound difference with alkaline batteries. I only have experience with NMH and Lipo rechargeables. Havent really compared them to alkaline though. I have read that Lipo is supposed to have the 'best' sound. Not sure what that means. I think any battery will for sure have less noise than a mains connection. I think it comes down to price and desired voltage. I got some real cheap 14V Lipo packs and put them together to make a 45-50V pack for the Quickie. I think it sounds better than compared to 30V NMH packs that I have for my t-amp. I'm a cheap bastard so I cant stomach the thought of having to go through disposables.

If the voltage is high I would go with Lipo. Low voltages you are stuck with NMH. Forget Nicads.

Every voltage source has an internal resistance that slows the release of energy.  Like low ESR capacitors that can dump energy into a circuit when needed a low series resistance battery might sound better.  It can be measured/calculated.

Grainger I think the resistance difference between the nicads, is what caused the difference in sound quality in the head amp.
I have read a lot about batteries on the forum, however I will use alkalines until I decide on my final choice. I am also researching the option of using motor cycle lead acid/gel batteries.

Bernie,

MCM Electronics has a wide supply of SLA (Sealed Lead Acid) batteries.  I would buy from MCM but I have a Batteries + just a few miles from me.  They stock them as well.

Thanks Grainger, I'll check it out
