Do 5-pole DIN tonearm connectors deteriorate the sound?

In theory, one would think that any connector is worth eliminating when possible, and I have two tonearms with direct wiring from cartridge to phono stage, but in the case of other tonearms I also own and use and that do use the DIN connector, I cannot honestly say I hear any "problem", when I have compared the SQ of the very same cartridges in the very same audio systems, mine that is, comparing straight through connection to DIN connection. Is it possible that there is the tiniest loss of fine detail? Yes, but as connectors go, I think the Cardas DIN connector, if you’re using both male and female halves, is a very good one.

I read the referenced section on the Origin Live website regarding solder joints vs DIN connections, and I have no beef with that, but I do wonder at the concerns related to resistance of the wiring. In many phono stages, especially but not only tube phono stages, a resistor is deliberately inserted in series with the signal, right after the phono input. This is usually to prevent oscillation of the first amplification device and in tube units is typically 100 ohms or so. So why be concerned about a few ohms of resistance in the wire when the signal is going to encounter a much larger in magnitude series resistance inside the phono stage, before any amplification or RIAA filtering?

My preference is to keep the DIN in place because that allows me to run 2 differently configured phono cables - I have 1 specifically designed  for MC cartridges and a second one specifically designed for MM cartridges.

Retaining the DIN allows you to optimise the cable for your cartridge/phono stage.

For me this flexibility outways the disadvantage of having a DIN connector.

Another alternative is to solder the tonearm wires directly into the phono cable to eliminate the DIN connectors.

I am of the opinion that you want as little as possible between the cartridge and your phono stage. I want one wire, cartridge clips to XLRs (or RCAs).  The Schroder arms do not even have a solder joint in the way. They use Litzed wires which are a PITA to solder. 

Reed and Triplanar can also be purchased optionally with straight cartridge to phono wiring, as were both of mine, to name only two of several other than Schroeder.

I just went through this decision making process to Din or not to Din when ordering a new Origin Live Encounter. My current Rega arm has Incognito wire from clips to RCA. I went with the Din setup for convenience. I hope I made the right choice. :)
