I have owned both and while I think the 668b is technically superior (imaging, separation, detail ect.) I found it to be not very musical and to be fair it is marketed as a studio monitor. To be honest I've got a fair few Superluxes and the only one that I find to be good for musical enjoyment...

You should really be thinking about an amp/dac combo for use with a PC. I would suggest getting the E07 or E17 with the E09.  When either are docked with the E09 they work as an off board dac improving sound quality and of course they can also be used on their own for added portability. You just...

I recently bought the Mk2 primarily to use with my 32ohm K550 and though this is my first tube amp I can honestly say it sounds fantastic with these headphones.  The current models have variable gain and with the gain on medium it drives them brilliantly - I never have to go more than half way...

I've owned the V6 and the K240.  I found the V6 to be quite detailed but a bit 'tinny' sounding and ultimately not outstanding in any way.  The K240 have a really nice warmish sound with nice midrange and are good with most music. I would say they are a clear step up from the V6 but really need...

I don't know for sure but I would bet they are the same headphone but with a built in microphone/remote.  They got just as good a review on What Hi-fi anyway and can be found on Thomann for only 68 UK pounds plus postage so if the remote does not bother you I would say go for it as that is an...

Thanks for the input.  A more relaxed sound is what I'm looking for so I've decided to go for the HD600.  I think there are too many negative views out there about the HD650 like being veiled and having overpowering bass to take the risk although I could probably research for the next year and...

I've always wanted one of the above Sennheisers and I now have the opportunity to purchase one thanks to a surprise P.P.I. repayment from my bank.  It is to compliment the closed K550s I have which I think are great but would like something a bit different sounding rather than similar.  I used...

I think Grado SR80i/Alessandro MS1i are the best I've heard for fast paced rock though I realise you don't want these.  Only other one I can recommend is the Goldring DR150 though I still would recommend the Grado option over this. I found the AD700 to completely lack any kind of bass and think...

Quote: For rock you are best with Grados.  If you find them uncomfortable try the bowl pads.  Another one to think about from my experience is the Sony MDR-V6. Over ear and fairly bright with plenty of energy and detail so good for rock but beware fakes as there are many.  Nice starter...

This makes me feel better about the $25 dollar shipping fee plus $50 customs charge here in the UK.  I have them waiting for me in  the local depot after 3 weeks.  I sure hope I prefer them over the SR80s as they work out about the same price if you add on the shipping/taxes.

Driver sizes do vary considerably. 50mm is considered quite large and many full size headphones use this size of driver.  To my ears the size does make a difference to the sound.  I feel the larger drivers generally sound more accurate though not always the case.  Depends on the headphone.  The...

I'm guessing that you want something low profile for out and about and for your budget I can recommend the PX200 II.  They sound a lot better than the 202  (I have both) and are more discrete.  the AKG K518 is another to consider though I found them to have too much bass.  They were fairly...

Quote: The 662 and 660 are closed,  the 668b are semi-open.  None of them really sound at all like Grados.  Out of the headphones I've tried only the MDR-V6 sounded remotely close to my ears, but they were still no where near similar.  Of course there are lots of other headphones out...

Quote: Since you say vocals are important for you then maybe the 668 is not so ideal being that vocals are midrange.  Out of the 662f and 660 the 660 would be the safer choice but I think the 662f are more revealing.  Bare in mind I have not heard the normal and 'b' versions of the 662 and...

Anyone out there with some know-how on this kind of thing?

Thanks for the input guys,  I guess all these comments make sense of the matter.  Now here is a good tip for unsatisfied HD660 owners - if they sound rubbish try them with a Fiio E1!  

Lately I've got interested in old hifi gear to use in my loft and I saw this late 90's Sony flagship DVD player on Ebay for peanuts. It came today in almost as new condition with original packaging and manual but no remote.  It was to be used as a cd player but when I tried it with my amp the...

Ok I know this is controversial but I recently owned some Superlux HD660s and the best they ever sounded to me was using my little Fiio E1 out of my iPod.  These are 150 ohm headphones so they were surely being under-driven, however the sound seemed just right. Every other amp I've tried made...

Quote: The 662F are worth a go too.  Preferred them to the 668 as they do not have the nasty recessed mids.  Bit peaky at the top end but then so are the 668.  The HD660 are good too and have a slightly more laid back signature with no fatiguing highs but I think the 668 and 662 have...

  Quote:   I'm not best qualified to answer but since no one else has offered any advice I'll give mine based on SR80i ownership.   You definitely don't need the E9.  E7 would do fine amp wise.  E10 is meant to be better and E17 better again plus is portable like E7.  Depends on...

I've been listening to my K240S with my new JDS Labs 18v cmoy and they have never sounded better - even with the E9.  This really is a cracking amplifier.  It sounds great with these headphones.  Quite warm but really gets those drivers working well.  The dynamics and seperation ect. have really...

Quote:   My 601s are easily a class above in every way.  I can't really think of a reason to go with them over a Q701 other than to save money eg. for an amp.  If you start talking vintage K240 then that is another matter....   The K240S is nice for the price but not the best.  It...

Quote: That is interesting.  I'm sure some K701s are made in China.  Who knows maybe just the Q701s are made in Austria now.  I'm happy enough with all of my AKGs though my vintage K141 ARE of a higher quality than my Mk2s though I put this down to them being from a different era and...

Well I got the Denon and hooked it up to the E9 and it sounds very good. I think this Denon DCD-F102 has a DAC used in their high end CD players.  Not sure how it compares to the E7/9 with the pc as I've not bothered to A/B it yet and to be honest I don't expect to find much difference anyway. ...
