Headphone Amplification

Back in the '70s the amp wars were on, and Japan (Sansui, Pioneer, and others) challenged the burgeoning U.S. HiFi (yes, that's what it was called back then) stalwarts Marantz, Fisher, Scott, McIntosh, and Harmon Kardon with high quality, low cost premium gear. Heck, even Sony had a presence in high end, high quality iron in those days. Much of that gear is revered today, including the relatively exclusive Pioneer Series 20 line. I was recently fortunate to land a Series 20 M-22 Amplifier - 30 watts, Class A, and as sweet as any amp I have ever heard - right up there with any Pass Labs, Krell, McIntosh, or Levinson. When I got it, it was in very good (7.5/8 of 10) c…

Hello to all forum users! My name is Martin and this is my first ever post, so please bear with me if I would make any kind of mistake. I would really appreciate if I could get some help please. I need to convert 100v Japanese amp to be working with UK power supply. I believe it could be re-wired; i am just not sure what wires and what pins on PCB needs to be changed. Also, I am looking to install XLR balanced inputs, is there any simple schematic how to do it? My DAC has an pre amp so the volume control on the 323A is not necessary. thank you for your time and help best regards Martin

Hi, Check this 12000 euro amp out. There are so many $10k amps popping out these years. They come from workshops. Actually, I doubt if they are really worth the price.

So I have this nice new LG OLED TV but my receiver can't pass 4K video through it since it is too old. So I need something that will be HDCP 2.2 compatible I believe. I have a Marantz SR6005. I've been really happy with the Marantz receivers so far and would like to stay with them unless there is something significantly better that won't break the bank. Trying to decide between SR5011, SR6011, and SR7011. Any thoughts? This will be for a 3 (maybe 3.1 at some point) setup. Setup: PS4 Pro/Apple TV/Oppo BDP-105D -> receiver (would use DAC in receiver for everything buy music and would use the Oppo for that) -> TV and Monitor Audio silver ser…

Got an email from Todd @ TTVJ, he has this for pre-order, looks interesting with a Korg "NuTube" triode.... http://www.ttvjaudio.com/Apex_HiFi_Sangaku_Headphone_Amp_and_Pre_Amplifier_p/aaa0000998.htm http://www.apexhifi.com/Sangaku.htm

Currently there is a Woo WES and a HeadAmp KGSS-DX listed on ebay. http://www.ebay.com/itm/262862948306?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT http://www.ebay.com/itm/192110146358?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Going to be interesting to see what they go for.

Hi everybody! Greetings from Barcelona! This is my first post and I want to thank the attention of anyone who responds. I'm interested in buying a tube headphone amplifier, but I have a low budget so it would be interesting to hear some advice from more experienced owners. Looking for through the web I have ended with two interesting candidates: the Little Dot Mk II and the Appj PA1502a. Both have received quite good reviews (not many, but there are some) for the price so I'm undecided. The Little Dot is a class A OTL push-pull amp, while the Appj seems to be a class A transformer output single ended. As for …

I was skimming some hi-fi magazine this weekend and I noticed the announcement of this product. Teddy Pardo is mostly known for his aftermarket power supplies for Naim products. Does anybody have experience with this amp or his other boxes? There's very little useful info on the product page (e.g., gain or power), and no reviews yet.

Hey guys, @justin and I are excited to make our first offer on the burgeoning deal site Massdrop: it's the Original HeadAmp Pico DAC/Amp! https://www.massdrop.com/buy/headamp-pico-portable-dac-amp Get in soon, to save up to 50% off the retail price of $499. This is a limited-time, limited quantity deal, and once the Picos at this price are gone, they're gone. The Pico DAC/Amp uses an ASRC to upsample signals of 16/44 and 16/48 to 24/96 before converting them with a well-regarded Wolfson DAC chip. The Pico DAC works without drivers on Windows and Macs, and works on some Apple iOS products when paired with a camera connection kit, and select Android d…

This has got to be a misplaced decimal or something http://www.ebay.com/itm/331996665716?ul_noapp=true

Thoughts on Eddie Current Black Widow?

seriously, somebody gotta take a look at this $3.5k amp, grab some pictures from the net, that dac board shouldn't be there, we can not see the whole main board now.

I thought this was an April fool at first, but apparently not! If you fancy a good laugh have a read of his review @ the other place http://www.head-fi.org/products/cavalli-audio-liquid-gold/reviews/10823 Just to whet your appetite Only Solid State Amp I've heard that Sounds Like a Hybrid: The Texture and Warmth of Tubes, but Control, Power and Precision of the Very Best of SS! From DAC or phonostage - to various musical genres! It just goes about its business and does its job better than almost every other amplifier I've heard. Perhaps the most musically engaging of them all actually - but I'm still figuring that out! Pros: Outstandingly Musical and Easy…

I noticed on Headamps website that the new version of the Aristaeus includes numerous improvements in parts and build quality. Has anyone here heard a V1 and V2, as to make any comparison. What parts have been changed and such? Justin or maybe the denizen electrostatic gurus. Thanks, Gary.

I am thinking of selling the Stello stack in my office (HP100 and DA100) and just using the Pico Dac/amp there with the AD2000. The Stello stack is probably better but most of the time I am working (or at least pretending to work) so I don't think I will really notice much of a difference. The thing I don't want to deal with is plugging and unplugging the amp when it needs to be charged. I think the Pico stops charging the battery when it is full and runs off the PS so I don't think there will be a problem keeping it plugged in, right? The only thing I thought of is that a rechargeable battery seems to discharge over time so it may often be discharging a bit and then …

For some reason which I can't explain, I wandered over to the Cavilli website today and saw that the Liquid Lightning 2T was selling for $2499.50. Original price was $4250. Wonder what's going on?

Just found this article on the web: http://inearspace.com/2015/05/22/questyles-cma800p-breathes-magic-into-stax-a-munich-high-end-show-2015-report/ Stax themselves comissioned Questyle to design the preamp. Info and internal pics of the preamp: spam deleted What do you think? Price is rumoured to be around 3k usd. PS: They also did a "golden edition": spam deleted

It's a hp amp/preamp, I don't know what to say about its PSU, is +/- 60V necessary?

Hi Guys I run a KGSShv that take about an hour to warm up and sound 100% performance. Because of that I tend to leave it on all the time unless I am going away for a few days. My question, is it ok to do that and leave the headphones plugged in, or is it best to power down? The headphones would i guess get a 580v bias but no music signal during this time.

I would like to build a Solid State balanced amp and need recommendations. I have LCD-2's non fazor to power. I've built in the past(guitar amps too) soldering skills good, I'm not coming up with anything besides B22 amps. Suggestions please.

Has anyone built a high quality transformer / convertor to run Stax headphones out of the speaker terminals of a power amplifier? I know there has been some negatives about the Woo Wee. I am thinking is there a much higher quality option that can compete with the KG Stat amplifiers and that is safe i.e. won't damage the headphones or the power amplifier feeding the converter. Many years ago I used an SRD-7 which was ok, nothing great. Any information would be much appreciated.

So apparently they followed the "Glass FX" tube DAC and integrated with a headphone amp. Dual 12AX7As. http://www.jolida.com/product/glass-fx-tube-headphone-amplifier

Interesting -- a minimalist headphone amp design from Grace...good, compact choice for work? https://www.massdrop.com/buy/grace-design-x-massdrop-m9xx-dac-amp?utm_placement=0&referer=JKRU5U
