There are precious few phones that do not sound good with the D4, IMO.
Like the ES7's :/

my d4 has a very loud hissing noise when used with a rechargeable batt. this noise doesn't happen with alkaline batts or the USB cable. can anyone advice? thanks.

That sounds bad, I'm planning to use rechargable ones. I know absolutely nothing about batteries, but have you tried more than one rechargeble? Talked to Ibasso about it?

Mine is quiet with rechargeables or alkaline.

Hi, would there be any damage in using a 9.6V rechargeable battery in place of the regular 8.4V batteries ? - VAPEX TRUE 9.6V 220mAh PP3 9V RECHARGEABLE NIMH BATTERY - eBay (item 350267769950 end time Jan-18-10 21:47:47 PST)

Just placed an order for the D4. Am I to understand that if not not satisfied with the product, I can return it for a refund within a particular time frame?

That is right, you can return it within 14 days.

Perfect then, I have nothing to lose. Fingers crossed it synergies with the IE8.

honeyboy, you have to ask where you bought it from

anyone can provide me with a link of great combination of opamps for the D4, i would really love to read to 32 pages this thread has but headache and flu isn't really helping.
thanks ^^

I think that someone here once posted that the circuit inside had components rated for 10.2v and above that you might have problems going higher than that. Typically the 9.6v batteries are safe in 9v products, but while they give a better voltage swing they don't last as long as a typical 300 mah NiMH battery (or the 500 mah Lithium that Jamato8 uses).

I have the 9.6 rechargeables and they work fine. I haven't really compared the sound to the LiPoly with the 500mA and lower voltage but I like the run time of the 500mA as Larry mentioned.

Changing battery would be a thing of the past.
....
Am wondering if you guys think its possible to mod the D4 such that the battery (a 9V rechargeable batt) charges itself when connected via USB?
Changing the batt is quite a pain.
