Guys, maybe it is too early... but in any case any of you have heard the Shure SRH840... how does it sound compared to other closed/open headphone that you have? I'm particularly interrested to know how it is compared to Sennheiser HD25-1... Thanks, --- David

Hi Alvin, thanks for your reply.... and thanks on your found about the HD600 and K701 matching/unmatching with the MPA2.5. It seems that many people at the head-fi mention that K701 have better synergy with tube amp... I'll follow your development on your other amp :-) that you say sound like tube amp... Thanks, --- David

Hi Alvin, I'm not new in SGHeadphones... but I've been inactive for quite a long time... so that I do not follow any latest activities around SGHeadphones. I saw in your blog posts, your MPS2.5 pictured with K702... What do you think the difference between MPA2.5 driving the HD600 and K702? Regards, --- David

Hi TGR, where did you get the DAC? I'm still waiting a NOS Philips cd player with TDA1549... which I read is a close DAC to TDA1305T (the difference would be only the default oversampling received) I'm interrested to try the TDA1305T DAC as well... Thanks, --- David

what about for half of your budget but will sound very good? Check Crossroad Mylar 1 X3 at Jaben at Adelphi... http://www.jaben.net/ This is my highend budget IEM... (I'm not kidding... and don't be fooled with the price...) --- David

Hi Joi-ful, thanks for your update... maybe last time I do not spend enough time to listen to UM2 so that I did not notice the hump that you mention... one thing that actually sounds strange to me is... UM2 sounds very powerfull/impactfull... which is too good to be true... I mean I'm not sure if that kind of impact is really on the recorded material... (see my opinion on the http://www.sgheadphones.net/index.php?showtopic=5495# and http://www.sgheadphones.net/index.php?showtopic=5495#) UM2 sounds more powerfull than MS2 or DT990... when I hear UM2 before I listen to MS2 and DT990.... I'm really amazed by UM2... but after I heard MS2 and DT990... I later think that might be UM2 is not right... any way... if I have a chance I will try UM2 once again... I will check SF5pro too... (too bad, might be I don't have a chance to visit Singapore again this year...) Thanks... cheers, --- David

hi Joi-ful, I never hear shuffle... last time I hear UM2 with my notebook earphone out... and I don't think I hear no bass bloat at that time (I admit I only have a short time to hear it. Also my notebook earphone out sounds "neutral to cold", which match my warm SR60)... What kind of bloat? is it boomy or is it loose? Thanks, --- David

Hi Joi-ful, May I know... when you hear UM2 have strange bloated bass... what player (or equipment) that you use with it? Thanks, --- David

If you want to use Decware SET SE84C amp, why don't you ask Steve Dekert on what "budget" speaker that his amp would happily to drive? From what I read SE84C is different then normal SET amp... which prefer stable 8ohm impedance... SE84C can drive 2 ohm safely... (at about 4WRMS..., since at 8ohm it can only deliver about 1WRMS) Speakers with >= 89db sensitivity usually come from: Tannoy (M2, M3), KEF (check Q1, Q3), JM Lab, Triangle, some B&W, JMR (Jean Marie Reynaud), etc... SET is not for: Revel & Dyanudio check AHFartaudio, he has Fostex horn... Regards, --- David

he, he.... Bram, apa kabar...? I'm about to post this chip too... I check Farnell still do not carry it... I wonder whether any reltailer carry it... Jadi pulang ke Jakarta? Regards, --- David

Yes... Aron got it right... that's how WBT always suggest for terminating cable to their plug... my version is abit different... I don't cover the whole cable unto the braid using big copper tube... instead I use small size copper tube... (usually used on aircon or refrigerator to carry refrigerant fluid between radiator and the blower) to cover only the braid/mesh wire, which previously has been unbraided and then twisted tightly... crimpt it tightly... so that it seems the the tube and the wire becoming unite (copper is soft right... it also provide airtight-ness to the previously exposed wire) and then screw the connector to the crimped part... with the small copper tube it is possible to screw only to the crimped part without the crimped part touching other ground part... Do you know where this idea comming from? Bullet plug... I try to reduce the connecting point between the wire and the metal part of the plug... just like bullet plug... on bullet plugh you solder it right on the two small part of the plug... so that the electron will flew only to the concentrated joint... theoretically this should reduce time smearing... of course this only valid for plug with screw on the ground body... like WBT and some other cheap plug... (I think DAIYO is quite good... if you can find the one that is non magnetic) Regards, --- David

Hi guys, I want to share some experience that I know about DIYing interconnect... I once had a "business" of selling IC with Belden 89259 in Indonesia... (not run for long time enough... only managed to sell about 20 pairs... and have no time to follow on...) 89259 is good cable as it is... the key to make it sounds (if it really have the sounds :-) good is the good RCA plug... but there is something more important to make it sound good with whatever RCA plug that you use... read on... I once try it with many variations: from cheap tiffany style, cheap thick style, Canare (original) tiffany style, Eichmann copper bullet plug, and Neutrik Profi... From all above plugs... I can only say that it never sound good enough with tifffany style plugs, including Canare... whatever way... including soldering the braided shield wire as close as possible to the ground part of the plug... It also sound not good enough when I use a cheap thick plug, when I solder them... Later I found that soldering the braided wire like the shield wires on the 89259 is not easy... it acts like soldering wick... and this is added with the fact that thick plug need very hot solder to get the thick metal get enough temperature to melt the solder wire... that's why I never been able to make a perfect joint by soldering the braided wire to the thick plug... thus it cannot sound good... the 89259 start to sound good with the thick plug when I experiment like this... the central conductor is still soldered... but the braided wire is... I cover it with copper tube and pressed it... then I screw the tubed wire with the screw of the thick ground part of the plug... I make it such that only the screw that connect to the pressed copper tube (so the copper tube never directly touch the ground part of the plug)...It works well... This is the main combination which sell most during my business day... It beats my own QED Qunex 2 and based on my customer feedback, it beats Nordost low end interconnect too... I can understand now why WBT always suggest to use crimped copper tube to terminate cable to the gound part of WBT plug Then I use Eichmann bullet plug... the 89259 sound more focus and balanced with this plug... this has been long become my own interconnect in my system... before permanently replaced by Eichmann Express 6 cable later on... (no contest at all... Express 6 is few league better) Then since bullet plug has reliability problem... (it is 95% plastic) I try with Neutrik Profi... To my ears it sounds quite similar to bullet plug for the 89259... 89259 with bullet plug has been tested by my friend and comparable head to head to Kimber PBJ. PBJ is meatier but 89259-bullet sounds more focus... both has very close character... 89259 with bullet also head-to-head to Nordost Black Knight, but with different character... 89259 more balanced and relaxed and BK has better bottom and analytical... So as good as it is... standard 89259 (I never modify the cable; like twisting it or others) is respectable cable... I think I already push it to the maximum performance when I use Eichmann bullet and Neutrik profi... the result is repeatable... since then I also sold some IC with bullet and profi, the sounds character is stable... Another so..., termination is one other key to make 89259 (or any cable... or any electronic part joint) "sounds" good... both bullet and profi are easy to solder... thus produce perfect joint with the cable... Cheers, --- David

Mackie... is spot on... Regarding the DAC..., Joi-ful... please give it a check... An AKIRA DVD (I think only about Sin$40) (even better if the digital coax RCA out modified with BNC jack)..., combined with a good DAC... could sound better than most budget cd players... REgards, --- David

Hi Earphoners, I check that few days back Aron mention that he has d-Jay sample with him... Anybody has tried it? Impression to share? Thanks, --- David

Sorry... I make mistake... Sovtek 6n1p... actually I mean to mention Svetlana 6N1P...... because in the past time I do not hear about Sovtek making 6N1P... (I know that Sovtek making 6922 but... not 6N1P) So 6N1P model always relates to Svetlana... Until I found: http://en.wikipedia.org/wiki/6N1P So I realise now that both might come from the same "Voskhod" factory... REgards, --- David
