Let me first provide a little background as to how I got here...   My initial setup was Neko Audio D100 mk2 feeding balanced into Audio-gd Phoenix, feeding into balanced Sennheiser HD-800 with a DHC Molecule balanced cable. Not a bad setup, I thought. And, given the "jitter-immune" nature of...

Hello all! I currently own three pairs of Grados - black SR-325, semi-vintage RS-1, and HP-2s - all balanced running out of an Audio-gd Phoenix. While I enjoy them all very much and my journey so far has finally led me to those three pairs of Grados after an extensive array of headphones, I...

I got a decent deal on the rather dated Timbre TT-1 and jumped for it. I hav always been a big fan of older but well-designed digital gear so I am hoping I will enjoy this DAC. I couldn't find much info about them on the web though, only few traces I could gather were that the sound leans...

Apologies if this is old news, but I was at J&R in downtown NYC yesterday and saw that the SR-60 and SR-80 they carried (but curiously not the SR-125) had new plastic housing that looks very much like the larger 325i housings. I was so curious, I wanted to just grab them for the sake of trying...

Simple question, really: is the headphone jack on the front of the Melos a completely separate circuitry that is not shared by the balanced outputs at the back? In other words... I want to know if I can use the Melos to drive my Grados in balanced mode from the rear balanced outputs and get...

I need some help from other Grado HP-1000 owners! I recently acquired these babies, and have been listening to them for about a month or so now. My first impressions were that these are perhaps the closest thing to the Ety ER-4s I've heard (this is a very good thing for me) - fast, detailed...

I know it's an odd question since there is no real standard for I2S connectors but I am aware of a few manufacturers using RJ-45 for "proprietary" I2S connections. And the inexpensive and handy Pop-Pulse SPDIF-II unit also has an RJ-45 I2S output (with clear labeling of the pinouts). My next...

I've been interested in non-oversampling DACs for a while, but never had a chance to hear one. Recently I purchased a Gigalab Moon DAC on eBay to finally give them a shot. At $200 shipped for a nicely built 8x TDA1543 unit plus a host of input options including USB, I thought I needed to give it...

It was winter, it was cold, it was a cold winter... (giggles) OK so it's cold outside and I'm sitting here wondering why I have a fantastic sound card (Echo MIA MIDI) that is capable of balanced outputs and I'm only using it as a single ended card, despite my HD580s being terminated to a...

I just noticed something funny about my GS-1. When volume is turned all the way down to zero, there is faint signal coming from the right channel while the left channel is completely silent (or at least I can't hear anything). And, my GS-1 has the DACT stepped attenuator installed so I doubt...

OK so I think I am one of the few members who has actually owned and heard the Echo MIA MIDI soundcard. That was a few years back. The way I recall - very clean and lively sound. Punchy and dynamic. A bit "digital" sounding, more analytical than organic. Powerful but neutral. A few years...

...I have decided to return to headphonedom. Primary reason? Winter's coming, so I'll be spending a lot more time indoors, and I've got a new desktop computer so I am a bit more tethered to the desk than before. Ever since I got the iPhone the day after its launch, I've sort of ditched the...

Hello, As a previous user of the Ety ER-4 series (both S and P) and now the UE-10 Pro, I am still pondering the question as to why the much cheaper and simpler constructed ER-4 sounds so much cleaner (less smeared) and accurate (less distorted) than the vastly more expensive and complex UE-10...

So, I bought AudioDIYLab's DAC-201. For those unfamiliar with it, here's the product link: http://www.audiodiylab.com/shop/prod...products_id=45 And an image in "stock" form: I bought the bare board and got custom components to go with this USB DAC+Headamp. Notably, the "upgrades"...

A few I can think of are DT770, W1000, W5000, etc... But, I've only tried the DT770, not quite my cup of tea, and the CD3Ks I've tried in the past aren't that isolating... I love open cans but it looks like the apartment I'll be moving into in a few months will have a loud air conditioner...

Hello everyone! So I am extremely bored over summer, and I was reminded of my old TPA6120-based balanced headamp project. I was excited as I found something to kill time with, but I realized that when I reformatted my computer a while back all my Eagle files and libraries that I had built up...

Hello, Is it possible to run the AD8066 in a simple buffer/voltage follower configuration without a feedback resistor but instead the negative input connected directly to output? This is what I'm talking about (voltage follower): Thanks in advance!

Hello, Is the easiest way to create 6V out of 24V to use two TLE2426s to split 24V into four 6V sections? Thanks in advance!

RS-1n: "n" for new, "n" for nude. So, this is really the second part of my crazy RS-1 mods. The past threads regarding all my RS-1 mods are as follows: doobooloo's RS-1 mod, part 1: wood facelift (pics) My modded RS-1 is absolutely astounding!!! Modding my RS-1s... Suggestions? Modded...

I just got a used PortaPro 2 and would like to replace the foam pads (a bit worn/oily/hairy). Where can I purchase them? Thanks in advance!

Recently I put in a dual opamp buffer section for my balanced TPA6120 amp. I had an AD8620 in there for a few days, but I thought the sound was slightly congested compared to without the buffer (but then no onboard volume control) and also compared to my AD8066 based balanced MINT. So, I was...
