Oh that makes total sense, stupid me Anyway I forgot what this function/technology was called where the music goes directly and unprocessed through to the soundcard and out to the amp. A particular mode that I think you can make for example FOOBAR 2000 support. Anyone knows about this?

But the sound is really good!! I'm just sitting here being one big smile listening to the tunes of Guns n' Roses and Genesis in lossless FLAC on with my HD600's Definently an improvement from before, no placebo involved. Especially noticable at higher volumes. So crystal clear, defined and...

Hey guys! Hehe I don't know if anyone remember me anymore, I was posting a few times some 100 pages back, somewhere around november/december 2007 I was looking for a headamp and chose the Zero. I even chose some custom opamps, don't remember which anymore. I recieved it in mid-february and...

I just ordered a Zero + OPA627 DAC for 241$ incl. shipping to Denmark. Wohoo I can't wait! I figured that I might find the purchase of upgrade headphone opamps more satisfactory if I can actually hear the difference at some point so I just went with the default ones. My Senn HD600 just...

I think that I remember Penchum declaring his love for the LT1364 specifically somewhere through the first 127 pages though I can't seem to find it anymore. Have anyone else tried the OPA627 / LT1364 combo other than Penchum? I'm considering to just take the default headphone opamps whatever...

Quote: Originally Posted by Penchum Ok, here we go... If you buy OPA627's on the dog, times 2 for the headphone board, this is going to cost like $122 at current Lawrence prices. That is too much I think! Since you don't have a Zero yet, and have no idea of the sound the default Opamps...

Quote: Originally Posted by biph911 The "he" in that sentence is Penchum. Sorry for my errant pronoun usage. What the.... did he just correct that or did I mis-read it the first time around? So it looks like LO1469, LT1364 and LM4562 would be a good choice. I've emailed...

I wonder about this: Quote: Originally Posted by biph911 Analog device DY2000 (dual, metal) Price: US$35. Comment : It provided very similar results to the DY2000 ceramic but the sound is ten times better with their punch , detail , range of frequency ….. especially the naturality...

Quote: Originally Posted by biph911 He actually rates the OPA627 as great on the DAC side in each combo. The OPA627 hasn't been used on the headphone side (yet). Who is "he" I thought Penchum made the chart

Nice, I just got in touch with Lawrence. He tells me that he recommends the "Burr Brown OPA 627 BP(single, ceramic) on Browndog adaptor" for the headphone opamps, and I'll take his word for it. What about the DAC opamp, how would you rate the default, Penchum? On your chart you say everything...

Quote: Originally Posted by biph911 The two on the headphone board are identical since they are just L & R. If he shows LT1361 / LT1469, it means the DAC opamp is a single LT1361, and there are two LT1469s on the headphone board, one for each channel. An exception would be the...

Quote: Originally Posted by Penchum There is one Opamp for the DAC section. There are two Opamps in the Headphone board, L&R. We discovered some time ago that changing the DAC Opamp will change the sound of the DAC output and the headphone output. If you change Opamps only in the...

Oh forgot to ask how many opamp slots are there? Just two right? Otherwise the amount of combinations would explode exponentially, that wouldn't be nice =/

Quote: Originally Posted by Penchum The Opamps are in sockets, so you pull one out, push one in. Very easy. Oh... :/ Damnit I should payed more attention to your extensive talk about the opamps, didn't know it was that easy!! Btw is the opamps used in the DAC, amplifying...

Just another question, how do you change the opamps? Does it involve advance stuff like soldering or is it just more like changing RAM on a PC motherboard plug n' play?

No proposals for opamp upgrades? Haha you've all been basically blabbering on about good opamp combo to upgrade the zero with for approximately 120 pages or something and now you can't name a few for me? What

Awesome. Well it looks like I've found my amp. With features like fairly high quality sound, DAC, Amp, Pre-amp, Coax/Optical/Analog input, all for such a great price is simply makes the Zero irresistable. I thank everyone for their suggestions along the way you've all been a great help
