Hi, I have a zero dac/amp and I'm currently pretty happy with the opamp setup I have, the DAC section has an LM4562 and the headphone outs have LT1364s in them.  I know a lot of people have used discrete opamps in the DAC section (like the audio-gd 'Moon' or 'Sun'), but I was wondering if there...

I found this mod for the Little Dot I+ with the LM4562 being used as the opamp.  Apparently this guy soldered Blackgate NX Hi-Q .1uF/50v resistor (at least I think its a resistor) to the actual opamp.  What are the benefits/why would someone do this?  Any thoughts ... ... my main concern...

So I bought these headphones a while back figuring, $25 after shipping was something worth investing in even a mediocre pair of headphones, and they've been sitting around my house for a while.  The other day I got the bug to mod them, they have 50mm drivers which I figured have to be useful in...

I'm looking at a pair of Yamaha YH-2 Orthodynamic headphones, and I saw that there was a tome written about Orthodynamic headphones and that there are a lot of fans of them on the site.  For a pair in very good condition, what do you think I should pay for them?  Also, because of the thin...

I am looking for a new DAC, and I wanted to know if anyone had any experience or comparative experiences with these two (or three) different DACs.   I wanted to know specifically the comparison between the Audinst and the Little Dot DAC II (as they appear to have similar capabilities, but...

  Anyone out there have a rockboxed 5.5 80gb and a 6th gen ipod and done a SQ comparison both through the headphone out and the LOD?  I wouldn't imagine that the LOD should change to much between the stock firmware and rockbox on the 5.5, but maybe it does ... ?   I'm facing a serious...

I was thinking about getting a Little Dot DAC II, which many on this site have raved about, and I was going to connect it to my macbook via S/PDIF using Amarra and iTunes as a source.  I have a pair of Shure SRH-840s which certainly are not Senn HD650s or AKG k701s but they are really good warm...

Hi, I was thinking about getting the Little Dot DAC (I or II, don't know, doesn't make a difference in this post) and I wanted to know if I'm using my macbook as the source which output is going to yield the best result, USB or the optical via mini SPDIF (my red lit headphone jack )   Know...

I have played most of my audio from my macbook via optical to a ZERO DAC/AMP to a dot I+ hybrid, but I just plugged a RCA to 3.5mm into my pocket dock directly from my iPod into my Little Dot I+ amp and I compared the sound quality between the two, and I was surprised to find that my iPod's...

Hey yall.  My current rig consists of my macbook > Zero DAC/AMP (DAC only) (via S/PDIF) > Little Dot I+ hybrid tube amp.  All of my components are fairly cheap, so I know I'm not gonna get any love from the super high-enders here on the site, and I'm certainly not bragging about the setup.  What...

I'm looking at a little dot I+ tube hybrid amp, and I know that the opamp is what is actually driving the cans, but the information about the stock opamp in the LD I+ says its better for lower impedance cans.  With the OPA2228 upgrade will it drive higher impedance cans like my Beyerdynamic 770...

I just want to start this post by thanking all the members who have helped me make decisions in the past, and who have guided me in the right direction.  I have learned so much by reading through head-fi posts and I hope to learn more from those who respond to this post.   I am looking for a...

I was wondering if it is possible to upgrade the opa's in the fiio e7 to a higher quality set.  I know NOTHING about OPAs or how the fiio is setup, all I know is this from an engadget spec review:     Quote:   Does anyone out there think that the AD8692 or TPA6130A are upgradable...

So I just plugged my FiiO e5 into the line out on my iPod dock and the sound was a LOT LOUDER than I had expected, and once I turned down the sound I can't tell, but it feels like my headphones don't sound as good?? The sound was loud pretty loud, but probably only 3 - 5 seconds. It also seems...

I have a pair of Shure SRH840's that have a relatively low impedance (40 ohms) but I love their sound (really incredibly, better than the Beyer's I tried for the comparable price - 250 ohms). So, I've been thinking about getting a headphone amp to make full use of my new cans. I already have an...
