You are perfectly correct, the problem is that different battery types require different regimes, just to add to the madness :mental:Quote:

NiCd, NiMh, Lithium Ion, Lead Acid (& then depending on the battery type to), what a nightmare for joe public! :rolleyes:
Exactly!Quote:

The charging and low voltage cut off is taken care of by the pack's built in circuits, so no worries there. Discharging at too high a rate is another killer, however ~ 100 mA is nothing for this type of battery, so no probs there either. :)
Lithium batteries don't have a memory effect, so you don't have to cycle them like the old nicad or nimh types. You can keep them topped up with no Ill effect.
Hi Martin - deferred, I'm afraid, as the charger failed while I was trying to put a full charge into the battery to start tests. I've made a claim and await a replacement charger.Quote:

Cheap Chinese charger. What can I say?
You have said it Martin ;)Quote:

Have to check the specs to see if it will charge the Hong Kong thing.

Cheers,
Well i have let my bushmaster burn in for over 150 hours with the occasional listen.
My set up comprises of a thin client computer running win XP and Foobar2000. A Teradac usb to spdif converter with independent power supply, a Tripath amp with valve buffer and some open baffle speakers.
My old Dac was a modified AK4396.

Swapping to the Bushmaster straight off was an improvement. I didn't realise what digital glare was until the change.
Hopefully after the burn in period the Dac will not change its qualities too much. I can confirm what others have witnessed. The holographic effect is superb. I have had Stans other Dacs including a gatorised Caiman with Maplin P/S and i have never heard this level of holographic quality. The way it places the vocals in their own space and then adds the instruments around it is a revelation to me.
I received the Mark Grant SBooster today and this has taken the Dac to another level. It has not changed any of the characteristics of the Dac, things just sound clearer. you can hear the the plucking of the stings on a guitar and i can follow the separate instruments with ease. for just under £30 its a great upgrade.
