    Analog Squared Paper Discussion Thread.

    Thanks, in that case the 15000mah version should be sufficient for a day's operation (one full cycle on the TU-05 internal batt + 1 external battery cycle), should have some left over for charging phone or DAP..   I just checked the size of the 20000mah Anker (185x125x15.5mm) and it is almost...

    Analog Squared Paper Discussion Thread.

    Hi GermanGuy, great to hear that, what's your operating time like with the 10000mah batt?   I might buy the 15000mah instead of the 20000mah if you are having 'reasonably good' operating/charging hours on yours...  Thanks.

    Analog Squared Paper Discussion Thread.

    Wow, that's huge, however the 52800mah batt is only available for pre-order, while the Anker has ready stocks with a local seller.   If you guys think the Anker battery will work since it has the same 12V as the A2P provided charger, I'll just grab it. I'm just not too sure and I don't want to...

    Hi guys, do you think this Anker Astro Pro2 Battery will work for the TU-05? It is 20000mah and will provide 12V for 4A. Going for a long bus trip (10hrs+) soon and planning to take the amp along. Thanks.   http://www.ianker.com/product/79AN20L-SA#ptop

    Singapore Meet - 7 September 2013.

    Jgray91, write it as truthful as it can be, rckyosho is right, no holding back. So that further improvements can be made (if I had more time). I have only 1 pair of ears and it is old :) so the more the merrier ;) Rckyosho, I'm still thinking about the Ember, dunno if I should get it first or...

    Portaphile Thread

    1. I meant to reach out to those who bought the Mk3b or SR-71B and have been using it fully balanced in/out, and have recently bought a 'latest and greatest' single-ended portable amp.   2. I do understand that some who bought these amps (Mk3B, SR71B) might only want to use it single-ended...

    Portaphile Thread

    Quote:   Hi guys, is there anyone who have the portaphile 627/x and the RX-Mk3B or SR-71B and compared the performance with the balanced function of the latter 2 amps?   To Aero Dynamik: was your above comparison using the single-ended or balanced mode of the Mk3b?    The reason I...

    Orthodynamic Roundup

    I have several pairs of ortho headphones, and of those, quite a few pairs were HP50A/S. I found that each pair had slight variance in the sound characteristics. One HP3 was almost perfect with stock damping, great soundstage, just a little lacking in the bass, the first pair of HP50S I bought...

    Orthodynamic Roundup

    :) that photo looks familiar, almost forgot about it. The HP50a/s are my all time favorite as it was a joy to mod and whenever I need to go portable.   Though I'm still wondering how I can successfully mod the YHE50 without damaging the clips...

    Orthodynamic Roundup

    Hi guys, need some help with replacement ear pads, I am buying new earpads to replace the old ones in the vintage headphones. I am looking at pure leather options as I find the faux leathers too warm/hot.   I have been researching thru this thread and the web and have so far only found ESW9...

    Orthodynamic Roundup

    Thanks Rhythmdevils, I am slowly understanding what the different ways of layering, shape and sizing of the felt does to the sound, even though it is only craft felt. This is my first Ortho and 2nd headphones. So far I am loving it, much better than my HD25i-II in terms of soundstage, mids and...

    Orthodynamic Roundup

    dBel84, based on several posts in the thread plus what you just mentioned, it would seem that the damping scheme is 'segmented' into different 'zones':   1. There is the 'rear of the cup zone' where most of you would place very dense materials to cover the vent. Would it be correct to say...

    What do you think of these felts? Are they feasible for damping?   http://www.bandmfelt.com.au/products/3mm-felt   http://www.feltshop.com.au/product.asp?pID=57&cID=1   http://www.cagroup.com.au/Malthoid.asp

    Yup, in the order of :   earpad, baffle, greyish black disc, white disc and then the driver..

    Orthodynamic Roundup

    The white disc [some kind of fibre glass type material? I was able to wash and dry them :) ] is in-between the stock greyish black disc and the driver.   Would it be right to say that if I damp or try to block/seal the vents, I will get stronger bass? Sounds like a plan. The headphones is...

    Orthodynamic Roundup

    These are the craft felt I bought. From the left is the denser more compressed black felt and to the right is the less dense blue felt. The second photo shows the amount of light passing through.   I read from the posts that natural felt with wool is better then synthetic (the craft felt?)...

    Orthodynamic Roundup

    I dismantled the HP50a and gave it a good scrub with the toothbrush. I resoldered the drivers into a 'stereo' configuration and gave it some damping with the craft felt I found in a shop.   I don't know if it is the bass lite version as some mentioned in some posts, I can hear the bass going...
