My first toughts about this thread was "omgwtfbbq", but something came in my mind while reading all this.

When i was into electronic RC-racing, the very best soldered an capacitor onto the batterybundles in the car, not to boost the voltage but to have a clearer, protected and stable voltage.

With those very low cost MP3-players [size=large]i DO[/size] think soldering a capacitor on the circuit can enhance the SQ, high end PCDP's probably have this already in its IC.

My Go-Vibe sounds horrible on a nearly flat alkaline battery, with a NiMH it works great, then just stops working when the Nimh craps out. Of course alkalines usually last longer though.

nicd/nimh run at 1.2v, because they can maintain it through out the charge.

Alkaline are 1.5v because their voltage droops some with use.

I do recall batteries suffering from "memory effect" tended to sound the same.

Indeed nicd/nimh are 1.25 volts, alkalines are 1.5 the first five minutes of use...

I'm probably not that one person referred to, but I notice a subtle difference in the tightness of the bass response between lithium and nimh when it comes to 9V battery packs. But that's a different scenario that the single cell discussed in this thread.

The lithium pack probably has 3 cells at 3.6V and some regulator beyond that because it gives a steady 9vdc. The nimh pack is just 8 AA cells. So I'm guessing it's mostly the regulator. Might also be the slight voltage difference--freshly charged, the nimh pack is about 11vdc. Could also be that there's a lot of connections between all those cells. Don't know if the different impedances of the type of cell makes a difference, although it might affect the current delivery capabilities, but maybe it adds up in all those connections.

Haven't done the comparison of 9V nimh vs 9V alkaline.

Why bother with batteries? I just steal electricity from the grid

This is what you do:

yea, so make the cord longer and you will have unlimited battery life

 

[bellsprout]

all i know is that duracell nimh rechargeables recharged in an energizer recharger sounds a lot fuller and wider than energizer rechargeables recharged in either energizer recharger, duracell recharger or various other brands of rechargers, especially the ones with a nimh/alkaline switch rather than specialist nimh rechargers.

also, although a 1000mAh battery lasts 10 hours in my amp, i tend to recharge it after 2 hours, else the diminished supply voltage adversely affects the sound.

This is the best thread EVER!

Yup... makes ya' wanna' take up a crack habit just to see if you can find some way to get on the level of some of these folks...

I suppose this is probably in the same league as £250 power cords. Some people swear they can hear the difference, others point out the miles of cheap-ass shared copper between you and the power station. Others chime in with scientific explanations.

May I be the first to say "ABX tests or it didn't happen"

 

[apeculiarnoise]

I will only use one of these. The standard offerings by Duracell and other major battery manufacturers pale in comparison to having your own nuclear reactor. I have found from repeated A-B tests that nuclear power has, on average, less interfering noise than wind, natural gas or coal power.

For the ultimate SQ you can't beat potatoes. Lemons are ok, but French potatoes are best. 1999 was the best year IMHO, although 2003 wasn't bad either. Warm weather this year will probably give them a mellow, laid back sun baked sound.

New Zealand potatoes are an odd one. Nicely extended bass and full sound, but somewhat mushy at the top end. The detail is somehow mashed. Peeling may help as electrons tend to flow along the skin of a conductor.

 

[wgr73]

Lol...this is going nowhere

 

[h939]

The nuclear reactor seems a bit out of my budget

I'm in the US, so would Idaho potatoes be ok? Again, they should be a bit warm to compliment Grados. Microwave or oven?

Idaho potatoes are a good midrange choice, but for highest quality import from Germany.

Oven beats microwave BY FAR. The microwave will significantly dry out and color the sound (bad for Grados), whereas a good oven baking will create a fuller presentation.
