DIY headphone amp kit w/crossfeed?

http://www.head-fi.org/t/460669/strip-board-cmoy-revisited

The above amp isn't crossfed, but is so very simple it shouldn't be too hard to add a crossfeed on board - mount the crossfeed off the amp circuit board, even easier (think, crossfed adaptor cable from source to amp) - especially the meier crossfeed, it's simple & compact. There's a build guide somewhere on here or the internet that's easy to follow. google diy meier crossfeed.

i'm about to build my first diy amp and the only/entire reason i need one at all is to play with crossfeed. I strongly doubt you will find a kit that contains a crossfeed as standard, without spending a load of money - like the $200... i'm going to build a stripboard cmoy from the above link. It's the simplest diy head-amp i've ever seen by a whole long way.

the other alternative is buy a fiio e6 - they're cheap and perform - and then make a crossfeed cable.

Examples? It always seemed to me that a good crossfeed (especially an adjustable one) was a non-trivial circuit. Maybe I'm mistaken.

Adjustable? could be made so, i guess.. Meier's pages on his crossfeed detail a hi-med-lo-bypass setting for it, on the link the OP put in his post.

Trivial? you tell me sir, i said in my post that i'm about to build my first DIY amp precisely so i can experiment with  the crossfeed i put together inside of two minutes following the above tutorial. I'm not new to electronics (by about 25 years) but i am new...ish to DIY audio so i bow to your superior knowledge.. mine went together easily enough for me to use the admittedly slightly flippant 'make a cable'

Good crossfeed? again, you tell me. Seems it was good enough for Jan Meier. 

As for examples of a cable.. well i've never seen one but use your imagination.. tiny little casing fitted in-line with the circuit from the above link in it, constructed point-to-point like that - i did my first one that way for later ease of reuse. Might not be pretty...  mine's a lot bigger and uglier because i couldn't find caps that small locally.

For a 'first major electronics project' as stated by the OP - or for a 'first DIY amp' as stated by me, a stripboard CMOY with the above crossfeed would be relatively simple and highly cost effective (cheap) to build, fairly customisable even at a later date, and a good learning experience that if all goes well, should even produce an amp that sounds good enough to use day-to-day (that was the impression i got from this forum, anyway) - those were my reasons for choosing that combination for my project. A fellow new-ish-bie's perspective?

*I* could be mistaken though.. in fact it's likely.. if i am, please enlighten me.

I am the one who stands corrected. That is a brilliantly simple solution. 

i like simple, it suits my character well.. lol

parallel pathways.. this is beyond my knowledge level.. but yeah i'd assume so.. different feed paths for different frequencies, more conductor for the signal to pass down. Would be interesting to see if a 'bass enhanced' crossfeed like in that link could be paralleled up with a circuit more tuned towards higher frequencies - if you look at the output graphs for Meier's design the high frequencies drop off in volume a lot.. almost seems to invert the input amplitude at high frequencies from an upwards curve to a downwards curve, once you get above (what looks like, on that logarithmic graph) about 800hz and to tail off to nothing after about 10khz

now i'm thinking i should modify my crossfeed mk1 to include meier's hi-med-low adjustment... perhaps a trade off in the amount of signal mixing at the x-feed to gain higher fidelity, then use that to find the level of crossfeed i like the most, and then build mk2 based on my findings? Hmm..
