Hey Flavio, good review!
I echo your feelings re the soundstage of the Yuins, but I feel this is due to the phones' nature, being an earbud. To get rid of the SS, just gently press the Yuins
into your ears slightly = little to no soundstage. I think it's an inherent advantage
open has over
closed in both in-ear and fullsize HP's. Hell, my old KSC75 has more
soundstage than any IEM
I've heard...I'd still take IEMs tho
I do agree that the Yuins appear to have great separation & treble detail, judging by my OK1. Where I most disagree (for my ears) is over the sibilance issue...I've tried like heck to hear bad sibilance on Triples but I just don't hear it as you describe. Occasionally, yes, but nothing painful or consistent. Page & Krauss 'Raising Sand' (FLAC/iRiverH140/RSA Hornet) for example, (& dear old Robert can record as a very sibilant singer IMO):
I hear clear 's' sounds etc, but not sibilant '[size=xx-small]s[/size]
[size=x-large][size=xx-large]S[/size][size=large]S[/size][/size]ss'....there
is occasional emphasis on some s's, but nothing that worries my dull old ears. In fact, the above album on the above set-up sounded
absolutely wonderful on Triple Fi. I don't really listen to GnR or their genre of rawk music ('Knockin...' was good tho!), but I tried also with Black Sabbath (Paranoid CD), again ,despite Ozzy's, er, vocal talent, couldn't hear bad sibilance....didn't hear it at all, in fact.
I do think the OK1 is a marvellous performer & a definite keeper, but it just doesn't have as many uses for me as my IEMs -it's no good in bed (steady..... I mean the 'chk chk chk' leakage, drives my wife nuts, understandably), no good on bus/train (nil isolation plus that annoying leakage) etc. Where I want to contrast OK1, is with my full size cans for listening at home. Out of a Linn system. That could be very educational.
And I do agree = drums!
OK1's do give a great feeling of acoustic space to each instrument, but I find you have to listen in a quiet environment to get the benefit of this quality. When I wear them out on the street, or on the bike, nix. I tend to not listen at loud levels, maybe if I did....but then I'd be mutton n jeff in a year.
I am happy,
very happy to have both Triple Fi and OK1 for the many situatuons I listen to music in. And I'd recommend either without a doubt!
EDIT\ @ Faichu -I wouldn't hold out much hope for an in-ear for PK1, if the OK1-as-canalphone is anything to go by. It makes a
great earbud merely an okayish IEM.
