I’m about to install a clip on heatsink on some TO-220 Mosfets. Do I need to put a heatsink compound on these or just clip on the heatsink and I’m done. Thanks for any help or advice.

Just wondering if these two specifications are the same or different. Some Headphone specs list sound pressure level and others sensitivity.

Just curious if anyone is using large gauge power cords on their headphone amps, such as 12 or 10 gauge. If your house wiring is 14 gauge, does it make any sense or is there any benefit using a larger gauge power cord. I believe in using a good power cord, but are the aftermarket audiophile...

I am getting a low level hum from my Burson Soloist SL MKII amp. When I turn on the amp,with volume all the way down, I hear a low level hum only on the left channel. Even with my interconnects disconnected the hum is still there. I tried another amp, but no hum. I'm assuming this may be...

Please check out my review of this amp at Partsexpress.com, mine is the first review. I also wanted to add that I opened up the amp and it uses high quality parts. Besides the main IC chip, the Texas Instruments TPA6120A2, I found a Burr-Brown OPA2604 and Panasonic FM Electrolytic Capacitors...

I have the Sony MDR-7520. When I start listening to music with these headphones everything is dead quiet in between songs and quiet passages. After listening for a while I begin to hear static on the left side only. Other headphones I use are OK, so it's not my amp or headphone jack. The 7520...

Does anyone know if an AD825 can be replaced with an AD8610? I have a Cary Audio Nighthawk amp and it uses 2 AD825's on browndog adapters. Could I possibly try 2 AD8610's?

:)I just got a pair of these cables and have them hooked up between my CD player and Schiit Lyr. The results were amazing! Highly recommended! http://www.sonicelectronix.com/item_38891_Stinger-SI823.html:) Oh yeah, also tried them with my Burson amp as well and were also amazing! I know these...

I was checking out the Audioquest website and they claim to be using what they call Perfect Surface Copper and also Purple Copper for some of their connectors. I did an extensive online search and could not find anything about this Perfect Copper, and Purple copper seems to be used with jewelry...

Just wondering what others might think about this one. I'm not against external supplies, but I prefer there to be an internal one with an IEC connection. This eliminates having to upgrade to a better power supply and spending more money. For example; the Shiit Audio products and the Meier Audio...

I was wondering if anyone has this power supply or has checked it out. SUPPLIER PSU - Firestone Audio Power Supply Upgrade - Power Supply 24VDC at 500ma. Seems it may work well for a PPA or PIMETA. Any thoughts?

Can anyone explain the main advantages/differences of having more reservoir capacitance, opposed to less? I'm using 4 220uf Caps in my Pimeta, which is the minimum suggested. Would more Capacitance here give me better sound quality? Thanks.

I'm actually referring to the OPA627 being used in the Pimeta with a browndog adapter. Is it actually Safe/OK to use the 627 this way in the Pimeta? I don't hear too many people mentioning the OPA627 for use in the Pimeta. Is it a better choice to use 1 Dual Op-amp on the L&R socket...

Not sure if anyone has mentioned the new Iced Earth CD "The Glorious Burden" yet. I've been listening to it for the last week and think it's really a great CD. I'm not a good "Review" person; but I was wondering if anyone else has it and how they like it?

While swapping Op-Amps in my Pimeta; I accidently put my AD8620/8610 in opposite. I put the 8610 in the L&R socket and the 8620 in the Ground channel socket(did not relaize I did this). I turned on the amp, heard a pop, then there was a horrid smell. I opened up the enclosure, and the 8620...

The AD8033/34 http://www.analog.com/UploadedFiles/...AD8033_4_b.pdf I don't know how new these are, but AD calls them "FastFETs". The 8033 is the single version and the 8034 is the dual. I just got both of them as samples from AD. I put both of them on browndogs and tried them out. So far...

I would like to know what other people are using for drilling out holes in their DIY Headphone Amp enclosures? All I have now is a Black&Decker drill that can only drill up to a 1/2-inch hole. What I'm getting at; is to be able to drill out the much larger holes for a Neutrik Locking Panel...

I just finished building a MINT. Here's the problem: LED lights. No sound at all coming from headphones. Re-checked all solder joints and jumpers, C1, R8. Looks OK. Nothing is getting Hot. Only difference is that I am using an OPA2134 chip opposed to the OPA2132 with the BUF634's. I...

Can anyone recommend a good quality insulated DC power jack for my Pimeta amp? I want to install it in a Metal case, and it is advised to use an insulated DC jack to prevent problems.(as per tangent's guide) Should I also use an insulated Headphone out jack as well? Thanks.

What part/component/accessory of the Headphone Hobby are you most addicted to, or pay the most attention to?

I know the Alps Blue is a great pot and I'm using one with my Pimeta; But, I was just wondering what other pots people are using besides the Alps Blue?(excluding the Panasonic EVJ). I know Noble is supposed to be very good. Any others that are just as good or better than the Alps Blue that...

Just wondering if anyone knows where tangent has been? I placed an order at his website a few days ago, but have not gotten a response. Just curious, because he responded very quickly with my 2 previous orders. Maybe he's away for the Holiday weekend?

I have a couple extra Dual SO8 to 8-pin DIP Browndogs, and would like to know: These are the ones that have IC1 on top & IC2 on the bottom. Is it possible to use these with only 1 op-amp? Another words; I would solder an AD8620 to IC1 and leave IC2 open. Or; do I need to "jumper" a...
