Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread
Yes you were right. One of the strands from the left positive was intermittently touching the ground. A few heat shrink and now it runs like a charm. Thanks- Audiodoc

Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread
My amp is working fine with SE outputs. Yesterday made a XLR silver cable for my HD650s. Whenever I increase the volume in any of the gain modes the overcurrent protection is activated and the red led is lit. I have not used the ground pin in the XLR male plug just pin 1 left positive pin 2 left...- Audiodoc

My EHHA is dead silent. One cannot tell whether it is powered on or off even at maximum volume. I have crammed a tube heater delay circuit two toroids a low noise regulated supply to my tubes in series a temperature sensor based fan assembly and amb headphones protection circuit in my chassis...- Audiodoc

Has anyone heard these China built AMB Beta 22 type amps?
I am building one will let you know. Don't think there should be any difference. Am buying from a reputed seller who I have experience with for 6 years. Sellers genuine nichicon and sk170 alps and other quality stuff. Wholesale prices of Silicon are far cheaper in China than the west.- Audiodoc

Android phones and USB DACs
I can also confirm that the Samsung galaxy S4 does not play with the ODAC however it plays with the FiiO E7 and rest of my DIY DACs. Hope the next software upgrade fixes this glitch or a cheap workaround software is available soon.- Audiodoc

You can try an 8audio enclosure like I have used. Will perfectly fit the EHHA. You can also add a tube on delay and headphone protection circuit. Check my builds.- Audiodoc

Brief Odac impressions
Treble rich tracks (mostly badly recorded stuff, oldies and Compressed heavy metal tracks). The revealing / transparent nature of the ODAC makes listening to them quiet fatiguing. The HM601 DAP with its warm presentation and high frequency slope is quite forgiving in this regard. For downloads...- Audiodoc

Brief Odac impressions
While it is true that the ODAC is a USB only DAC and lacks features like spdif, optical inputs, wifi etc., one has to admit that such a compact and value for money circuit is extracting the last bit of juice that the actual chip is capable of. I have the ODAC as well as many other DACs upto...- Audiodoc

Brief Odac impressions
If anyone wants to try treble heavy headphones with the ODAC a better option may be a hybrid or tube amplifier. This will definitely tone down the sibilance and infuse the lushness and warmth that many audiophiles love. To me the ODAC is very flat and detailed which in turn make the presentation...- Audiodoc

Brief Odac impressions
I am also using the ODAC with Windows 7 64bit versions without any problems. It takes a few seconds for the drivers to get uploaded. Try to be patient for a while while they are loading. Sorry for the iffy phrasing. Was typing in a hurry so used longer sentences without the proper grammar.- Audiodoc

Brief Odac impressions
The digital signal cannot be contaminated by the power supply. The only two reasons I can think of in the case of a USB powered DAC is that the 5v USB supply should be clean as it is powering the DAC. Secondly any sort of noise can be transmitted via the cable to the analog outputs of the ODAC...- Audiodoc

I tried to edit it however entering doesn't do anything. Possibly because I copied it from my local forum " Hifivision". You may read it from there as it has be presented in paragraphs. Will again try to edit. Was a problem with the opera browser. Could edit in internet explorer.- Audiodoc

Brief Odac impressions
This is the brief impression of my ODAC which I have been using for the past one and half months. Constructed in the FiiO E11 packing tin so both can be carried together. Copied from my thread on a local forum. http://www.hifivision.com/diy/26853-objective-dac-here.html ...- Audiodoc

Planning on a good rack. It is the EHHA which gets the hottest of the lot even when compared to the other amplifiers. Though the hottest thing should be the upcoming pass 5 amplifier for which I am searching some good heatsinks. I don't stack more than three, similar sized ones (e.g DAC...- Audiodoc
