Craigster... I've copied this over from the WM-Z thread (link below, I'll be posting there first with my findings)... the bass is there and it's deep when called on but there's a 'but'... I've got about 25hrs burn-in on the Amp's and there's a couple of niggling worries, one is bass definition, it's cloudy & muddied on 50% of tracks and still lacks any real definition across the board... the second concern is the hi's or lack of, I can hear them in the background but they are clearly recessed and annoyingly sibilant at times... the mids are fantastic, detailed & full bodied and a real joy... at present I am happy'ish with my purchase and if they burn-in as I hope (the bass & hi's issues sorted).... another annoyance is the split cable, I can't help but wonder if this is the problem... at one end it's substantial (headphone end), the source end it's flimsy and a tad too long (the IPod cable is the same but with phone controls), it appears this has been changed from the original photo's I saw.... I'm in touch with Cardas over a replacement cable.... and in truth, I'll be testing these against 2-3 others in two-weeks time... that said I am really enjoying the Amp's for 85% of the time, it's just the minor niggles.
my WM-Z post... reads a bit odd at first as I'm replying to someone...
I'll check your recommendations out on Spotify, cheers for that.... 60/70's soul is a great love of mine, Stax, Tamla plus The Dells, Delfonics, Dorothy Moore, Chi-lites, Harold Melvin etc etc
Got a real love of rock music old & new... love acoustic blues, contemporary-folk, jam-band and mountain jam-bands.... also have a great feel for music from my parents generation... house always had music on back then, think that's why my music taste is wide... that said I'm not a lover of rap, hip-hop or that crap synthesized voiced dance music that seems to fill the airwaves, makes me think I was brought up during the golden age of music, when you needed talent to make it.... I'm digressing...
back to the Amperiors.... not changed so radically today, the mids are a massive strong point with these, real nice.... bass is still lacking real definition still stifled and cloudy but it's deep... hi's are really struggling to come to the fore... hmmm... nice sound though and definitely the best on-ear headphones I've owned.... gonna try and get 200hrs on these in the next two weeks as I'm loaning my WM-Z to a hi-fi dealer for a week (they've got an event on, thought I'd let him show iPod users what they're missing out on), in return they're going to get in Beyer DT1350's & Audio-Technica ES10 for me to compare (they might be able to sneak me a listen to B&W's new P3).... this was always going to be on the cards when I got my Amp's... I'm also thinking of amping the WM-Z with the ALO RX3 (I'm in discussions with them over that one on compatibility & the dreaded hiss question, which I really can't tolerate any more).
