Not much info, but... http://j.mp/HSsiUj Seems to be amp/dac combo?

A couple of pictures from Craig to get it started: Very Moth-esque.

Hi everybody at Head-Case forum! It's a pleasure to finally join you as well. ) Lately I've been checking out the Woo Audio WA6 tube amplifier. Does anyone here have any experience with this product and care to share some impressions/experiences? How does it sound and compete with other amplifiers? Does it sound very tube-like, for example very colored and veiled? Is the tube-upgrades worth the money, both rectifier- and drivertubes? Does anyone have any experience in tube rolling? I really like the properties of transistoramps, and I currently have two, but I really want to try out a quality tubeamp. Which tubes would you recommend to achieve a sound si…

Anyone get a chance to listen to the Peachtree Grand pieces at RMAF (or elsewhere)? I'm looking for a dac/amp that'll do 24/192 over USB and this appears to be a contender. The design intrigues me because it permits user selectable signal routing via tubes or SS. I'm open to other hardware suggestions for a solution to 24/192 over USB. Trying to hold the line at $5K USD Peachtree Grand Integrated High resolution DAC ESS Sabre32 9018 - supports 24/192 asynchronous USB input Hybrid tube preamplifier - uses two 12AU7s High efficiency amplifier - 400 wpc stereo Galvanic Isolation State of the art headphone amp - signal is run through the tube stage [no mW spe…

why all the agro? stax didn't make two seperate designed boxes i know this can be done to eliminate the stepup blue cube and run a us ul power cord the rca plugs can be changed to new ones. other mods are also possible

Eyeing some Quad 22L2s to replace 12L-as. Really love actives as the less components the better in my book, but if going with an external amp (I haven't seen encouraging signs of ~$2K floorstanding actives) does anyone have a suggestion for a smallish unit that would power the 22L2s? Pretty out of my element with speakers. Was originally eyeing the Parasound Zamp v.3 as nearly everything else I have is half-rack, but if I'm not sure it will be up for the task from the numbers (if reading correctly). Even up for altering the speaker pick (Shelly's choice of RX6s is also tempting from reviews), but my limitation is they and the amp would be best if sold by Amazon (gift cert…

Copying KG and Birgir's posts from the Stax Huddler thread

So I chose to buy the AKG 450, however I saw a review that said these headphones should be listened with a 320kpbs and my music is only 256. Will it really be a big deal? Would buying a portable amp for it fix it? I also listen to classical. Also, what amp should I buy? I am looking for under $70 I thought about the Fiios E11. Any other reccomendations? Please help!

Any suggestions on an inexpensive low powered (10W) speaker amp? I'm looking to use it with the Audio Nirvana speakers I built a while ago. I was thinking maybe a T-Amp.

I assume others have been following the O2 amp, though I haven't been able to find it discussed here. After a fair amount of reading, I've become interested enough that I've gone on the preorder list for a UK-built example of the amp, due in 2-3 months. (Yes, it does look easy enough to DIY, but I haven't built anything in an age, and I have enough distractions in my life already.) Anyone else have thoughts on this amp? Intents to build or buy one? Disclaimer: I hope it doesn't need to be said, but just in case it does, this post is not intended as drama-bait. I know NwAvGuy has raised some hackles with his opinions. In particular I know he has harsh thin…

Hi, I'v been a long time member on Head-Fi, and decided to check out this forum (for a number of reasons). After reading multiple threads here, it seems there are a lot knowledgeable people here concerning the AKG K1000. I have 2 K1000's, one is hooked up to a Unison Audio Unico, which I find a great combination. I'm looking for a cheap amp, to set next to my iMac, so I can use my other pair with my computer at night. I read multiple recommendations, Class-T Amps, old Marantz and Panasonics (PX950 etc.). I searched, but they were actually quite expensive now on ebay (650euro+ ). I have a bass-light pair, so a little more bass on the amp is appreciated, maybe a bi…

I am trying to wrap my mind around what must go into a solid-state amp to explain a $4250 sticker price. I understand that chassis costs are often one of the largest expenses, but I look at that chassis and it seems many DIY amps on here are more impressive in that regard. It's certainly far short of the RSA A10, looks-wise. Unless there is a few ounces of platinum inside, this seems pretty outrageous. Or am I missing something?

Hi All, I have had my MAD HD Super for a while now, and I am very happy with it. I am not very versed in circuit design for audio, but I am curious by nature. Upon first glance, I gather that it is a simple but effective lower powered circuit. Since I know many here are very skilled in this area, I am curious about your thoughts about the design. I have no intention of replacing it; rather, this is me asking for a layman's explanation for how it works and how it compares to other similarly priced tube amps. I have attached the User's Manual in case anyone is interested in looking at it. I have never seen it on Dr. Peppard's website, but his regular HD Manual ca…

Done by a 3rd party who happens to own both units. Someone I trust who has no hammer to pound with. I see no reason not to post this, as it should be clearly duplicatable by just about anyone. http://gilmore.chem.northwestern.edu/picovspredator.htm

Likely due to laziness, I don’t have much patience lately for writing or even reading reviews so I’ll keep this short. It may be of limited use to others as it’s primarily a two amp comparison. My interest was how the new Apex Arete and Volcano competes with the earlier introduced (and owned) Apex Peak and Volcano. This is especially so as (another member pointed out not long ago) I tend to prefer solid states traditional strengths with a touch of tube-like warmth. I’ve kept a Luxman P-1u over a B22 for this reason and it’s also where I think the hybrid Peak is especially strong. The flavoring of the tube I used for the tests, and the one I use over 90% of the time, th…

I have an audio itch that needs scratching! So I have been looking for an inexpensive balanced DAC with a balanced amp built in. I found the Audio-GD for $500 plus $71 S&H and although most may have not listened to this unit I would appreciate if "on paper" the claims by Audio-GD are sound and make sense. http://www.audio-gd....1/NFB10.1EN.htm If you all have a potentially better alternative I would appreciate hearing about it. Cost is a major issue, I would "feed the monkey" by selling a few items. Thanks.

So our Rotel 1068 processor is starting to give up the ghost. I need to buy another processor or receiver. I have external amplification I am happy with so a processor is preferred. Since these things seem to change daily I am looking for recommendations. Does not have to be latest gen but at this point I do want HDMI switching. Looking at $1500 approx. although less is always nice.

So the amp arrived today. I got it set up, turned it on and no sound. I then noticed that the 6C33C tubes were not lit up. I shut it down and turned it on again and slowly the tubes came to life. i had it playing for about an hour and the sound slowly faded as the 6C33C tubes shut down. Any idea on the cause. I am waiting to hear back from the seller and I'm guessing I will need to send it to Craig to repair.

Since I saw a pic of the board, I was wondering if it is worth it to "clone" as a DIY project the amp. I found two very useful pics of the inside. Based on it, I tried to fill in the parts: Is it a AC coupled amp ? The two closest cap from the potentiometer are input caps and i'm wondering if the two electrolytic caps close to the 1W resistors are output caps. Also, I don't know the name of the componant below the left 1W resistor. There are two of them. I think the output stage is push-pull, it probably looks like this: here is what I got so far. What do you think ? PS: I don't know if it is the right section and if it is allowed on this forum, mods fell fre…

I bought a Pioneer A-27 Integrated Amp a few months ago and sent it to Hamad at Amplifier Surgeries to have it rebuilt. I and others here have had Hamad do wonderful work on Pioneer M-22 amps. Since I will be using this amp sometimes with headphones (but mainly driving my Sound Lab speakers) I asked Hamad to check the headphone circuit to make sure it is optimized as much as possible. He indicated he would and asked what headphones I was using so he could "check to see if the resistor network can be matched for my headphones". The hard part is I don't know which headphone to have this amp optimized for. The dynamic headphones I use are the LCD-2, HE6 and HD800. I l…

The SRM-1 MK2 pp (rev. C, spritzer modded to balanced input) was having bad resistors when I just got it. The bad resistors are those 2.2Mohm (R303 & R304) resistors. After fixing that, I like this SMR-1's sound even better than my new SRM-323S for some music. The bass is tight and impactful and the soundstage is more open. Recently, I changed the two diodes (D301 & D302) in the bias circuit with 1n4007. I also replace other two diodes (D101 & D201) in the L&R channels. I found the SQ actually went down (to my ear). The bass impact was weaker and the soundstage shrank. And the DC output from PSU seems to drop a few volts. Then I put the old …

Hello forum. So I have some new Grados. I need to feed them from my Macbook Pro. Narrowed it down to Centrance DACport and Nuforce HDP... HDP has moar features, but from what I can gather, the DACPort is friendlier to the Grados. I want something relatively small and portable for now, so tubes and desktop amps are out. So with all that in mind: 1) Can anyone recommend a good new-world red to go with venison? 2) What is your favoured Bloody Mary recipe? 3) Does anyone one know what this suspicious looking rash on the inside of my left thigh is?
