Thanks for the response, It has OPA 627AP's on all three channels. The buffers is the Laroccc Audio Triad board setup. Tim

HI all, I am currently having a problem with my PPA V1. I recently purchased a pair of Denon D7000 headphones which have a 25 ohm load. I initially built the amp with a gain of 10, but with the Denon's I had hardly any volume control. I then changed the gain to 5, which gave me more volume...

Cool Deal! Slow and steady wins the race. Geesh I am almost at post 30, I better pace myself.

I FIXED IT!!!!! Happy day! On a whim, I tried putting in the AD610 op-amps I had and now the heaphones are working great. Still unsure WHY changing them worked, but it did. Maybe one of the Burr browns was going bad? Thank you all for your help.

To eliminate the jack, last night I desoldered the jack in my meta42 (which worked with the beyers) and replaced the one in the PPA with it. Still did not work. I will try the steps kklee suggested when I get home. Thanks Tim

I have a steps power supply. PPA uses the Burr Brown opa637 and 627 op amps. Has the "Ultra Linear Discrete Diamond Buffer" also. I have ruled out the neutrik jack. I assume it is something in the circuit that does not like the Beyers. It works fine with my AKG271 Studios and my Senn HD580's...

I thouhgt so too at first. If it were true, It should not work in the cdplayer or the amp I have at home. All 1/4" plugs by the way. The home amp also has the same neutrik jack. I also tried leaving the screw-on adapter in the socket, and switching between the akg an the beyers. Akg works...

Hi all, I am having a strange problem with my new Beyer DT770's. They do not seem to work correctly when I plug them into my PPA amp. The left channel plays music very quiet compared to the right. If i turn the volume up, the left side will crackle. I thought it could be the neutrik jack on...

I have paid up as well. Thanks, Tim

I will take 2x Option B

I would say my two current favorites are Anouk - especially her album "Update" and The Waifs. Tim

Save Ferris, both CDs. The lead singers voice is amazing. Tim

I build alot of computers for people, so i have a few suggestions. Case: Antec Sonata. Very nice case, and extremely quiet. Uses 120mm fans.Hard disks and case fans are isolated form the case. Comes with a truepower 380 watt power supply. At Fry's for 89.99 + a 30 dollar rebate. CPU: AMD...

I have not lost any function. I use both ASIO and wav out for the 0404, both work great. I have full functionality with the Audigy 2 card, including the creative sound mixer. I keep the audigy as the default windows card. I have winamp and foobar setup to use the 0404. Tim

I currently have them both working welll together. I originally had the audigy 2 ZS in my computer and the latest drivers from creative. I then installed the EMU-0404, on bootup I canceled the add new hardware attempts from windows. I then ran the driver disk for the 0404. When it is...
