I have been on a bit of a journey with my portable rig.  I use an iPhone3 as a source with Apple lossless files.  I use a high quality LOD purchased from Head Direct into a CMOY running the AD823 opamp, from Deb's Extras, (set to bass boost) then into my Apuresound recabled ER4Ps with Shure...

I purchased several good quality IEMs to get decent sound out of my iPhone. I started with an Etymotic ER4P. It has a great midrange, awesome vocals, but the top end was a bit harsh and it lacked bass for my tastes. I next tried the Westone W3. Great sound, but I found it was too bass heavy and...

Hi, I recently purchased a pair of ER4Ps and love the detail. I'm looking for a portable amp that can drive these IEMs and also provide bass boost. I was surprised to find 2 amps that actually allow you to use the ER4Ps as ER4Ss through their impedance feature, ie, the Minibox E+ and the Xin...

As an experiment I wanted to put together an ultra small and portable rig that delivers high levels of isolation and sound quality. I do a lot of commuting by train, so I wanted the rig to be compact. This is what I did: I purchased a pair of Etymotic ER4P IEMs, an iPod 2nd Gen Shuffle...

Hi, Does anyone know the pin outs for the Headroom DIN power cable for their Desktop Power Supply? I want to make up a long power cable and I want to make sure that I wire the +ve, -ve and Gnd correctly. Many thanks, Nick

Hi All, I'm learning more about vinyl set-up. I recently purchased the HFN test record and found that my tonearm & cartridge lateral resonance was at 7Hz. It is just outside the lower end of what is considered optimal (8Hz at the lower end). Should I be worried about this? I could improve...

I'm new at electronics projects, but I'd like to build a CineMag SUT. Does anyone know of plans that a beginner could follow to bulid such a unit? Thanks DIYers!

I have downloaded the Stevenson protractor from the Vinyl Engine and I am using it to align my cartridge. I simply adjust the cart so that it lines up on the grid at the 2 null points. I move the protractor to align in order to the 2 null points. One thing I'm not clear on is how do I set the...

Hi, This is a real newbie question on cartridge alignment I know, here it is... I am currently setting up a newly acquired Technics SL1210M5G. According to KABUSA the prefered alignment method for a Technics is Stevenson. I then went to the Vinyl Engine and printed a generic Stevenon 2...

Hi all, I think I may have damaged my new Audio Technica OC9 II cart or my phonostage... gulp. I forgot that my phonostage was on, I pulled off the cart tags and aligned the cart, then I put the cart tags back on and now now sound. Actually, If I run the amp right up I can hear a faint...

I just auditioned a Stello DA100, DA100 signature and a DA220 Mk II. Although not exhustive it highligted some of the differences between them. Basically, the DA100 Signature and the DA220 MkII sounded very close, the only diferences where minor such as slightly more smoother and slighter...

Hi fellow headfiers. Anyone using the Audio Technica AT-OC9 MLII MC cartridge on a Technics SL1200? I am thinking of buying an SL1200 to replace my aged Rotel PR850 and Garott P77. From posts I have seen elsewhere the SL1200 seems best with good quality MM cartriges, however the AT-OC9...

Hi all, I am about to order myself a MAC. One thing I will miss is Foobar as I understand that it is Windows only. I currently, use the equaliser and the convolver in Foobar. Are there add-ins for iTunes that add DSP equivalents to an equaliser, convolver and resampler? In paricular I use...

Hi, I stupidly dropped my HD650s into metal speaker stands and dented one of the external grilles. Does anyone know how to dissasemble a HD650 so the grille can be pushed back? Alternatively, should I take the cans in for repair? Regards, Nick

Hi all, I am feeding a Headroom Desktop heaphone amp and DAC a 24/192 signal via coax. The Coax cable run is 5 metres. I occasionally lose the signal and have to switch the Headroom Desktop on and off to re-establish it. Could this be caused by the length of the coax cable run? Thanks in...

I recently started using the Resampler (Secret Rabbit Code) instead of the Resampler (PPHS). I immediately found the SQ out of Foobar improved, better clarity and and deeper bass. I am using optical out at 96K from my ASUS Notebook. I also found that you can resample to 192K if you have a...

I am thinking of getting the Musiland SRC10 upsampler so I can feed my Headroom Desktop balanced via coax at 24/192 from my notebook. Most of my music is redbook (16bit) but I have heared from others the the upsampler offers improved sound in terms of bass depth, bass quality, air...

I have been experimenting with my Headroom balanced amp from the computer-as-source side. This is what I have found running ASIO4ALL and Foobar: 1. Setting the resampling DSP in Foobar to 48K when using USB improves the SQ (to my ears). 2. Going optical and setting the resampling DSP in...

I purchased Headroom balanced desktop package with HD650s three months ago and have been listening to it through my ASUS notebook via USB. I discovered that the ASUS has an optical S/PIDF output so I purchased a Toslink cable. I also set Foobar to Kernel Stream and resampled to 96K. What have I...

I currently use an ASUS M6A Notebook as my computer source running Windows XP together with Foobar and ASIO4ALL. I connect via USB to a Headroom Balanced Desktop with inboad DAC and to balanced HD650s cabled with Equinox cable. The main issues I have with the Notebook and player side of this...

I have had my Headroom Desktop Balanced rig with the DPS and balanced HD650s now for 3 months and it would now have 300+ hours on it. This system has had time to burn in nicely and it sounds so smooth and detailed. I have recently received my Equinox balanced cables for my HD650 and have got...

I have listened to a Mitchell Gyrodec and it managed to have a very low noise floor, amazingly for a turntable it has very quiet. I also listened to a Rega Planer 1 and it did the usual TT trick of high surface noise. Any suggestions on what rig would give good performance and low surface...

I have just received my Equinox Balanced cable for my Senn 650s today. I am listening to a Headroom Balanced Desktop. My initial impressions are that the cable upgrade has delivered a small improvement in sound quality over the stock balanced cable. I'll burn these guys in to see if there is...

Interesting review of the balanced desktop (see link below). The reviewer seems a bit of a noob to me when it comes to the computer as source stuff. He also thinks that the Headroom amp is a bit foward! Man if anything it's laid back in my book. He likes the Rudistor better but gives the...

Does anyone know who can add balanced XLR outs to a pair of Alessandro MS Pros? Since I'm in Australia, anyone in Australia would even be better.
