hey Mike, just my .02, i've been using a copper/silver plated LOD for about a year now it was, from compicatx, out of turkey,http://shop.ebay.com/compicatx/m.html?_trksid=p4340.l2562 , he's reasonably priced and does great work, but customs sucked, it took 6 weeks to recieve? ugh!
i've also just bought a silver DIY low profile LOD from a fellow Head-Fier, and what a difference between the 2, my setup is a GS Voyager which is a very dark amp, 6.5 gen classic, and TF10's, and the difference the silver LOD has made is so significant, its brighter and airier, more detialed and revealing, it brought out the mids and highs in a more defined way, and has enlarged the soundstage by quit a bit, just the upgrade that has transormed my rig, and it only cost me $35.00, although it took 7 weeks to arrive from Canada ta-boot, what up wid dat? that smokes, need to get a new address, lol, but still well worth the wait
and boy oh boy, its just the sound i've been looking for, i thought something was wrong with my Voyager for the longest time, don't get me wrong it sounded great, but what a difference that silver LOD has made, and it being a low profile, i've got no more concerns on catching it on something, and ruining either the ipods or the amps connector, so i'm very very happy about the whole upgrade
I'm sure from one copper lod to another i wouldn't have noticed any difference, but from copper to silver, its a night and day difference and experience
i was worried about it not arriving and if it hadn't i was going to get this one instead looks like a good one, cheaper and similar to the copper hybrid your looking at aswell
