I had to replace the battery connector with a JST XH one but once that was done then its simply unplug the old battery, remove it from the circuit board (it was stuck down with a double sided foam pad) and plug in the new one.
Hi do you have any pictures / more details on the fitting as i have a nano black that needs a new battery
thanks

Has anyone reverted back to firmware previous to 5.3c due to sound quality?

Our 5.3c firmware applies our own GTO filter to all PCM data. Although most folks in here are happy with it, several users liked previous versions more.

I really have no idea how I missed this part about the Nano BL balanced... So if I get the right cable, I can get balanced output (like so many daps) from the Nano BL? I was considering selling and getting a dap with a balanced out, so that would be awesome. But honestly I'm not understanding the published material...

Does anyone have a recommendation on where to purchase a mmcx cable on the cheap? I've got the FDX1 and was considering balanced...

Edit: Or do most people use a 2.5mm TRRS to 3.5mm TRRS adapter? Does anyone have a favorite cheap one? It would have been cool if it had been cost effective for iFi to include one. I bet that would have gotten more users already invested in balanced cables to give this a whirl.

Since you can connect balanced IEMs/headphones to nano iDSD BL's headphone out, a balanced extender will work, of course given it's wired correctly.

Yes - you have to be careful and make sure the adapter is wired correctly - otherwise you run the risk of damaging the Nano BL.

Nano BL - "S-Balanced output works on TRS & TRRS headphones It is fully compatible with and supports balanced wired headphones on TRRS 3.5mm and the Chinese 3.5PRO balanced wiring standard maintaining the channel separation. That is, after all, the point of S-Balanced." iFi Audio

Before i invest in balanced cables and adapters, does anyone know if the volume of either or both 3.5mm outputs is louder balanced? I'm getting the sense from the circuitry (which I admittedly don't understand) that it doesn't act like a normal balanced output...

Looks like its output is 285 mW at 30 Ω regardless of what you connect to it, be it a 3.5mm TRRS or 3.5mm TRS. This would be using the Direct output I presume, not the IE Match, which has a lower volume and is meant for sensitive IEMs. The Nano BL is not like many Amps/DACs/DAPs that have more power coming out of a separate balanced output. In my experience using a 3.5mm TRRS balanced headphone cable vs. single ended, the volume is the same.

Hi :)

So a little background--regular balanced circuits double the number of amplifiers used, and thus doubles the voltage swing for up to 4x the power output--but this also increases the noise floor. Usually not as much as the max voltage is increased, but it is always an increase. To the extent that you listen to your amp at full volume, you will get an increased SNR (maybe at the last 6dB of your volume pot before max). To the extent that you listen to your amp at sensible volumes, or maybe you never ventured past 10 o'clock in the first place--you're probably actually losing out compared to SE. Sure you get increased channel separation but that's usually already astronomically high compared to any amount of crosstalk we can detect in the first place.

S-balanced works like regular SE in that only a single amp is used for each channel, but separates the grounds for the two channels for a fully channel separated circuit just like balanced. We don't have elevated S/N ratios to report with S-balanced but do have the same increased channel separation (soon as you update to a TRRS plug) and a non-elevated noise floor (which means better S/N ratios at actual listening volumes).

Cheers,
Joe

If balanced is not wonderful and S-Balanced 3.5mm is the best of all worlds, why do ifi make all their latest amp/dacs with seperate se and balanced sockets thus ensuring se is at a disadvantage as the ampliifer is less powerful?

SE on our amps is not at a disadvantage, it is less powerful yes, that is an *advantage* in many cases as it means a lower noise floor, even more so for extra sensitive 'phones that have no idea what to do with oodles of power in the first place. On full-size cans or planars that never worry about noise floor on any amp, but rather worry about power, sure, the 4-amp balaned output is more suitable. Different strokes for different 'phones. This is true not just for our amplifiers, but more true here because of S-balanced.
