Hello All! Haven't posted in a long time, but it's great to be back with so many audio enthusiasts. The reason I'm writing today is because I'm concerned about handling semiconductors, specifically transistors. I had bad experiences with my PPAv2 which, I believe, can be linked to the...

I build the PPA v2 but noticed only after turning it on that I had used an AD843 (not unity gain stables) in the ground channel. Maybe that screwed up the ground channel because now my Q33 (in the buffer section) heats up to the point where I can't even touch it anymore. I replaced all the...

i've heard great things about balanced amps in this forum and most of them are very expensive. The cheapest one I found was the headamp balanced desktop amp for 1k. Here's my question: will a maxed out WA6 SE ever sound as good as a balanced amp, especially one that costs less than the WA6?

Hey, I'm looking to upgrade. Ihave about 1250$ to spend on an amp. Anyone have any suggestions. My setup right now is in my sig. I was looking for a tube amp, doesn't have to be portable nor balanced. Thanks guys,

I just recently (a month ago) ordered an Ear+ HD amp and I think there may be something wrong with it now. When I start it up I hear a crackling from the tube - although I've read that that's normal -. The major problem is that at high frequencies I hear distortion. This only happens with...

Any one see these? I'm guessing the upgrade is purely aesthetic with the nice black finish. Other than that I don't know if they are any different from the K701s. Funny that AKG would spend time and marketing to get these out there. I guess its cuz they're having fun selling them for 540USD

I was looking at the headroom amps and was trying to see the internal circuitry from the pics provided. I really liked the internal wiring and could tell that quality craftsmanship was put into them. But then I started to ask myself: why is a desktop SS amp 1000+ $?? The passive components are...

Hey, I've been doing a lot of DIY stuff lately and wanted to start working on some interconnects. Problem is, I don't know where to get good Oxygen Free cables (copper or silver) which are high quality. Anyone know of any good suppliers? Thanks

I started asking myself this question as I started reading countless threads on this forum. At some point, you will reproduce exactly the original recording, but you can't go further than that. LPs that have been recorded 30 years ago, depending on the recording studio and the equipment, will...

Anyone ever try this CD player before? It caught my eye because it was a tube CD player and I thought it looked pretty good. Not sure how it compares to other CD players in that price range (seems most of the money goes to making it look cool...) EDIT: Shanling*

I was contemplating this setup with a Cambridge Audio 340C. Do you think the MAD amp can drive the 650s, because I heard they were hard to drive.

I just recieved my pair of Anti-IC's and let me tell you, on the first listen these babies outclass by Au24 by a mile, and only 100$ a pair!! Anyone else try these and/or love them?

Hey! I just bought a Mapletree audio Ear+ HD amp and was wondering what tubes would be best for use with AKG K701. Thanks!
