Headphone Amplification

Has anyone heard this amp with AKG K701's? Does the amp have enough output to drive them to decent listening levels? Looks well built. How does it sound?

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 …

I was wondering if an amp designer/builder can explain why so many people have problems running the hev70. Most of the are imported from the EU and it seems to be all sorts of problems yet they work fine in the EU. Is there any possible explaination for it?

See from Tyll's recent IF post Pete & Todd are at it again. On the other side of things, sadly the Peak & Butte are no longer listed on Apex.

I have a 2nd hand headamp aristaeus, the background noise follows the volume pot. I measured ac between L+/L- and R+/R-, the left is 3.48v when volume pot is turn to max while right is 1.74v, I swapped ecl84 and 12ax7 but still same value. Also I tried to adjusted vr p1, p2+,p3- but it didn't help, same value. May I ask how can I solve the issue? Thank you in advance.

It's an amplifier based on the stax t8000. I couldn't find the picture because the inside was not disclosed. It's an amplifier made by a famous Korean hi-fi amplifier maker and it weighs 60kg

Hey i have read some about the b22 and who'd want to know if some one have heard whit a pare of GS1000i. And want to share the conclusion.

Hi guys, I possess a wonderfull, like new, melos sha-gold and a pair of vintage grado rs-1!!! I need a pair of very good tube to use but, I've not sufficient money for experimenting different options... So between these tubes, which one is the best for my needing? Mullard E88CC-01 Telefunken E88CC Amperex 7308 Siemens E88CC A0 If you have other options in mind please let me know! Thanks in advance!

Anyone tried this amp? So far only positive opinions appeared on the other site and that it has great synergy with ATH-ESW10JPN. At the moment it is 299$ (excluding shipping) and comes with 12AU7 RCA Cleartop NOS tube. Should I give it a try? Thanks.

With my SP K1000 power amp nowhere to be seen, and with a potential need for a budget power amp for my Epos ELS-3 that I have setup for TV/Cable/DVD purpose, I've been reading about some gainclone amps. Most posts/threads about them are favorable and they seem to be great bang-for-buck. With that, anyone here has any idea how well (or not) gainclone amps will work with K1000's? My thinking is if it works well enough, I'll get one and use it to tide me over until SP power amp shows up, after which I'll use it with Epos.

Until now, I've been using the included GE 8CG7s in my 007t. Today, however, I received a set of Japanese-made B&K 6CG7s and swapped those in place of the GEs. I then went through the re-biasing procedures (akin to trying to enter a revolving door in the middle of a tornado). Now for the problem... With the pot turned all the way up, I'm barely getting any volume. This is compared to the ear splitting volumes the 86G7s put out at about 9 o'clock. Are the tubes bad, or did I not bias them properly?

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.

I am running a WA6SE maxxed (09 bulid) I also use Senn HD -800s. I am using a pair of rca 6ew7 big bottle and a EML 274B mesh plate. I ordered a EML 274B, but I didn't specify mesh or solid. I was sent solid plate. Used the EML 274B solid plate for one night and exchanged it for a EML 274B mesh plate. However I did really like the solid plate, great overall tone and soundstage. When I first got the EML 274B mesh I was disappointed. I now have about 26 hours on it. The 274B has improved but the soundstage is still not on a pair with the solid plate. My question is will my mesh plate improve or should I go back to the solid plate or get the EML 5U4G-Mesh? …

All I remember was seeing a MOT thread in Head-Fi several months back. It looks like it's been released, but I can't seem to find anything about it. So I take it no one has heard this anything anywhere?

I'm seriously considering purchasing one of these, and as of right now, is the only amp on my list. I've gone through and done "research" on many other amps close to this price, and the GS-1 seems to be extremely flexible with the headphones used (ie wide variety) and seems to be a top-notch amp. The GS-X, despite how badly I want it, can't afford it. Maybe I missed one, that you guys can recommend. And what's your opinion on this amp, for those who have listened or owned it. Any other recommendations on amps at/very close to $1,000? I'm not totally set on which HP I want, but am considering both the RS-1 and Senn 650 w/upgraded cable, or SR100's w/HP1000 drivers. A…

Hello! Please let me know which you would prefer and why: 1) The CIAudio VDA-2 DAC and VHP-2 headphone amp, both with VAC1 power supplies. OR 2) The HeadRoom Balanced Desktop. This model is now only available with the Home Modules and Home DAC. I will be feeding the DAC's optical inputs via a SqueezeBox Classic. Headphone suggestions welcome. Is going balanced worth the hassle of recabling headphones? Music preferences: Primarily Rock and Acoustical. E.g. Rush, Pink Floyd, Jose Gonzalez, Dire Straits. Channel Islands Audio HeadRoom Balanced Desktop Amp @ HeadRoom - Right Between Your Ears Thanks for your feedback!

I just received back from Cary Audio in North Carolina the Cary SLP-05 preamplifier. This is their top preamplifier and was purchased a couple of months ago to serve as my main preamp in my speaker-based system. I also wanted this to work as my home headphone amp when the wife and the neighbors want me to keep it quiet. The preamp is fully balanced and sports something unique in the high-end stereo preamp world, namely a true dedicated built-in headphone amp. The headphone amp section uses two 6SN7 tubes to power the headphones, while the preamp section runs off another six 6SN7 tubes, for a total of 8 tubes. The separate power supply uses 5AR4 tube rectification. You…

Hello, I'm new to audiophile headphones and I mean completely. I bought based upon recommendations on various websites an Aune X1S. I play Spotify with my iPhone 6 and sometimes my Mac. I understand that I can use an RCA cord to do analog. I want to know how I can connect it digitally? I read that I need an Apple lightning camera connector. Is this the one? Here is the back of the Aune X1S: Thanks for any help that you can give

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.

I own a pair of Transcendent Sound Beasts and would like to power the H2+ with them. Will this work well without the TR2? Thanks in advance to anyone who might know.

I am looking for an amp and would like to go with a portable(Zen Head, Mustang, ELO Mini3, etc) but would consider a desk-top for $2-300 if the sonic advantages were there. Do RCA inputs amount to better sonics or to the guts of the units decide that fact? And do desktop units have better parts, necesarily, than portables? The desktops units i'm considering are the new Trends, and any other that are priced $2-300. thanks

Well a couple of evenings careful experimentation has resulted in no explosions, I'm still reluctant to leave the H2 connected continuously to the SRM-717 until longer term verification that nothing bad is happening to the headphone or the amp. There's not a huge amount of difference between direct drive from the 717 and the Pass Labs/TR-2 drive. I'd give the nod to the 717 overall though. A big nod once you look at the difference in price between an adapter cable and the TR-2 of course. I also plugged the H2 into the SRM-212, and at anything other than the total bottom of volume control there's a mass of distortion and scratching sound as the H2 tries to suck every…

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

I just got an SRM-T1 (my first Stax amp) to go with 404LE (my first Stax headphones). I see there is an earthing terminal. Under what circumstances should I use this, and how should I use it? (Balanced cable specially made up?) TIA Nic
