Topic: Sonic difference between 3-wire or 2-wire with 4.7k mod?

[Cheesecadet]

Hello thought I wod ask because there are so many different threads on this in the past that I couldn't search them all.

I have a pair of AT853s that are wired to dual miniXLR cables. I was thinking about potentially joining them together to a stereo 1/8" plug with the 4.7k mod.

I know any folks have done this and are happy with result.

My specific question is does this change the sonic fidelity at all?  Does it lower the
Max SPL the mics can handle?  I figure there has to be some drawback to the mod but am not as familiar with it as others are.

Any info is appreciated! PM is great too or post here for others to see...whatever you like.

Thx

Anyone?

You probably know this, but there's no big reason to do this as a permanent connection. Darktrain can make a mini-XLR > 1/8 adapter plug with the mod so you can use them both ways.

Sorry, but I can't answer the Q about sonic differences.

Explain the exact differences in a language that is not mine it is very difficult for me.
I can tell you that I have made ​​many recordings with the various type of microphone is connected with 2 and 3 wires and I have not noticed big differences scores. The real differences are electric (incomprehensible if you're not a technician).
"IN MY OPINION" it's better (especially with your AT853) record with a 3-wire connection, it's important to have the right battery box with the "source resistance" calculated perfectly to your microphone and the output resistance calculated perfectly to fit the 'input impedance to the recorder. I think it's also important to use very short cables (max 1.50 / 1.70 meters) it's  used in the battery box tantalum capacitors (many disagree).
Having a battery box wrong lowers the maximum attainable SPL without distortion(equal to or less than 0.5%).With a 2 wire connection is fine mic-in, with a 3-wire hookup is consgliabile use a preamp and line-in input.

The whole reason why I came up with the 2 wire 4.7k mod was to give the same or slightly better performance over 3 wire. For the mics I build. the 4.7k mod does work well with mics using a 9 volt battery box. I use tantalum caps with very low esr. Thats how I build all my battery boxes. Also three wire boxes are bigger because they have bigger connectors not a deal breaker but you must build a bigger box to use 3 wire connectors. And since we are using these mics for mainly stealth. Size does matter. I maintain performance is as good or slightly better than 3 wire with my simple mod. But this is only when connectected to a 9 volt battery. Generally speaking I agree that the cable runs should be kept short as possible. Or you must atleast use a high quality low capacitance cable like mogami wire I use with all my mics.

Surely the system 2 wire / 4,7k at 9v is great for recordings with high spl .
I know your excellent microphones  ca-ST11, which are built with the capsule TSB-120 with resistor 4,7K source,I use these capsules since 2007/2008 (omni and card.) and I tried several times (even TSB 140, TSB165, TSB 99 and others) connected with 3 wire + preamp  or 2 wire with 4.7 mod / 5,1k I got good results with all 2 methods but to my ears it sounds better 3 wire (you have tried these capsules 3-wire connection?) .
Mini xlr connectors I agree that they are not suitable for stealth recordings, I have them replaced with jack 3, 5, the battery box is a good size (9x5x2 cm).

The capsules I am using are not stock tsb capsules. I have tried these three wire two wire made no sonic difference both listened to and analyzed.
