ok.. now i know im crazy.

Wait till you upgrade the RCA interconnects. Placebo theory should fly out the window.

Which one is better?

(There are two schools of thought on this. One school says the bigger connector will have better power transfer and sound better. The other school, inspired by the Eichmann eddy current theory, is that the smaller connector will sound better due to fewer eddy currents.)

Mike,

Its not silly. The differences you hear are real enough for you to question. I think you were entering the audiophile arena with a skeptical mind. Now that you hear something, though slightly noticeable, its real enough for you to double guess yourself. That in itself already makes a tangible difference to you. You just post your impressions and its what "your" ears hear. Not someone telling you what you "shouldn't" hear

I think you might be one of the few incidences that believe after hearing

Who cares what other people think, all that matters is you're enjoying you new components.

I believe this is a first time you're experience audio components of this calibur, which IMO are more suspectable to improvements from fine tweaks, rather then lower level equipment. This is why you hear a lot of people say "You won't hear a difference unless the equipment good enough to utilize it".

BTW, Your cables should ship out by tomorrow. Judge for yourself if cables make a difference when you receive them, don't let anyone tell you what you should hear.

regarding the 1/4" to 1/8" differences, Ive never bothered critical listening to the different connectors. It may just have to do with amount of surface area contact? I hate using adapters, IMO it only serves to deter the sound and add another element in the signal path. I have never seen a debate on sonics between connector sizes however, so whatever you are hearing doesnt seem to be influenced by other remarks.

I have heard differences between different connectors however, i.e. Cardas vs Neutrik vs Canare and so on or gold plated vs nickel vs silver.

God bless,

you will most definately hear a difference if that is what you are currently using :P

most of it will involve lower capacitance and resistance with the upgrade, and in turn should provide clearer imaging and higher gain, and loss of attenuation in the frequencies.

The DT880 is an amazing headphone... I feel the same way.

However, I think this 1/4" vs. 1/8" thing is probably placebo. Honestly, unless you're somehow listening to a 1000 volt AC signal, either of these plugs will transfer the signal identically.

Unless your amp has different connections internally to each jack, or something (seems unlikely).

They should sound different. One is direct wired, the 1/8th, the other is a screw on adapter, ie one more jump in the path. Much in the same way a splitter will affect sound a screw on adapter will as well. This is partly why the 1/4 phono with a 1/8 adapter is preferred outside the portable world

It depends on what that plug is being plugged into. If you are using the 1/4 because it will only go into an Earmax Pro, well, there you go. And you are using a mini because that's what a cmoy takes, well, there you go.

Are you using the same amp/source for both plugs? If so, how? Does that amp or source have two outputs, one for 1/4 and one for mini jacks?

this was my thought exactly. chances are you're comparing two different sources... and even if it's the same source, the two separate inputs would likely have more significant sound variation than the 1/4 vs. 1/8.

just IMHO, of course.

I think its simpler than that. What he is saying is the direct connection, 1/8, is different that the connection using an adapter, 1/4. Since its an extra contact point, it makes perfect sense that it wouldn't be 'the same' as the direct connection.

Just a word of caution... there may be a small difference or there may not be, but either way, if you start looking for the smallest of perceptual differences like this or let them affect your listening, you'll soon fall victim to audiophile neurosis. Faster than you expect, you'll end up polishing the contacts of your power cords, stacking your components on metal cones, treating the ends of your fuses with Walker SST, and thinking about buying the Nordost Valhallas. Some of the comments here are just enabling this kind of thing. A single extra set of contacts doesn't matter, not really. Don't buy in to that kind of thinking. It'll never make you happy. The guy who wrote the most words in this thread sells cables for a profit, and while I have great respect for him and don't think he's misleading you, it's tough to be objective when you spend a significant quantity of time building cables. I'm not saying cables or power cords don't make a difference, but don't get carried away by the differences. They're just not that major when you step back.
