  1. Still have the mutech 3+?

  2. Still have power cord?

  3. Begrudgingly selling a beloved personal amp from my private collection. The Liquid Carbon is a limited-edition, community-inspired, and carefully-crafted distillation of our Cavalli Audio house sound. There were three runs made, the final ones just have been distributed. Each run consisted of 500 units. The Liquid Carbon is a fully-discrete, fully-balanced, transportable solid-state headphone amplifier that is capable of driving all but the most demanding of headphones - delivering satisfying levels and offering superb driver control for exceptional detail and linearity. It’s fully-balanced as well, on both its inputs and outputs. In fact, whether your DAC has balanced output or not - and chances are that it doesn’t - the Liquid Carbon accounts for that with phase splitters on its single-ended inputs, so that it can “generate” balanced input signals. The Liquid Carbon also features adjustable gain (1X/3X), comprehensive input and output options, and ultra-low output impedance (~0.12 ohm balanced, ~0.08 ohm single-ended). All of the above combine to form something that is truly more than the sum of its parts… an affordable end game headphone amplifier. Includes: Liquid Carbon amp, Audioquest NRG-3 power cable (purchased separately for $100), and original box. $650. Buyer pays shipping and PP fees
  4. Selling a pair of good condition, fully functional, Sennheiser HD 600 Premium Dynamic Headphones. These are one of my favorite headphones that I've owned. The HD600s are one of the better all around headphones, and is great for both audiophiles and music production. The sound signature is very balanced, and works as a great reference headphone. Personally, I prefer them over the HD650 as I find the HD 650s slightly warmer and not as accurate. Specifications: Driver Type: Dynamic. Impedance @ 1kHz: 300 Ohms. Sensitivity: 102 dB SPL/V. Connector Type: 3.5mm (1/8") w/ 1/4" adapter. Cable Length: 10 ft. (3m) Cable Style: Straight Y (detachable) Weight: 9.2 oz. w/o cord. Includes: Sennheiser HD 600 HPs, HD 600 cable, case. Optional are wooden headphone stand ($15), travel case ($10), and/or 3m Cardas HP cable ($115). $225 Firm. Buyer pays shipping.
  5. For sale is a lightly used, Yulong P18 Power Processing Center in Black. Selling a very nice, fully-funcitonal, Yulong Sabre P18 Power Processing Center in Black. It has 4 power outputs, including 2 for Digital and 2 for Analog devices. It really provided a noticeable difference in my audio setup in combination with Audioquest Jitterbugs. Yulong P18 Features: Enormous ferrite core, wound with 11 AWG Pirelli wire Vishay 8uf X2 MKP common-mode filter Vishay Sprague Y2 differential-mode filter Vishay transient voltage suppressor used to avoid sudden impulsive signal noise LITTLEFUSE varistor (VDR) used for absorbing voltage surge Double layer parallel wide traces on PCB with 20 oz copper 11 AWG Pirelli wire used for internal wiring Schurter IEC inlet socket Cooper IG8300 receptacles Specially designed aluminum enclosure provides electromagnetic shielding Separate output levels for digital and analog equipment Phase and grounding error LED indicators 10 x 7.5 x 2.5 in (25.4 x 19.05 x 6.35 cm) 5lbs Includes: P18 unit and new 6' power cord. Asking $250. I'll cover PP fees; buyer pays shipping cost
  6. i just sold it yesterday.

    thanks for your interest.

  7. Is your Concero sold?

  8. These are a special pair of limited edition Grados that live up to their name. Grado started in 1952/1953 and has been thriving ever since. This year they decided to put out a pair of special edition headphones, and it's the first ever they've built out of a Brooklyn Tree (Maple). Given that this isn't their usual wood, it has some interesting differences from the other Grados, e.g. RS2i, RS1i, HF-1, HF-2, and even the GS1000. I find these to be more controlled but very dynamic in the midrange with improved clarity on the low and high end. I would find these most similar to the RS1i, but I find myself liking these more and more. I have owned a ton of Grados, and I wish I could keep these, but I have too many and I'll probably regret selling these like I did the W3000 ANV when they first came out. Technical Design: Vented diaphragm Wooden air chamber UHPLC copper voice coil wire Specifications: ◦Driver Type: Dynamic ◦Impedance @ 1kHz: 32 ohms ◦Sensitivity: 99.8 dB SPL/V ◦Frequency Response: 13Hz - 29kHz ◦Connector Type: 3.5mm (1/8") ◦Cable Length: 10 ft. (3 m) ◦Cable Style: Straight 'Y' Type Includes: Grado GH1 Headphones, Carton/Box, and Grado Documentation. I will also include a very rugged case made out of eco-friendly ballistic nylon. Non scuffing and has room for accessories ($35 value) If you're a Grado aficionado you'll like these. Reminds me of the run they did for Head-Fi (HF-1 & HF-2).
  9. This beautiful tube headphone amplifier was just built by one of my friends who is one of Bottlehead's lead engineers. I received this in exchange for some work I did for him. In addition to the expert build, he chose a beautiful color for the powder coat, and made the wooden base look very nice. Additionally, he provided a unique assortment of high-quality old stock American tubes (1 x 6080; 5 x 12AU7). Specs: -Input Impedance: 100K ohms -Output Impedance: 120 ohms -Gain: about 15dB into a 300 ohm load like a Sennheiser HD600 -Max Output: about 10V into a 300 ohm load -Power: AC 100-120V -Weight: 5.5lbs -Dimensions: 11.25 x 7.25 x 3.5 (L x W x H inches) $550. I'll pay for shipping; buyer pays for PP fees.
  10. I'm selling something from my personal collection. Didn't think I'd do it because you can no longer buy the temple pads for the K1000s, but I would like to test some of the newer upper headphones like the Focals. I ran these off of two 300B Paramount amps by Bottlehead. Regardless of what you run them off of, I would use the custom speaker tap adapter included as the output versus going directly into the 4-pin. The adapter cable is approximately 8' long and made out of nice Canare wire and uses high-quality techflex and a nice Neutrik jack. Just to add a little more about the temple pads. These are in 9/10 shape, which also indicates low hours. It is very rare to find a pair with this S/N that is in such a great condition. I'm not going to elaborate much on these. They're in very good condition and they sound unlike pretty much anything on the market. Furthermore, these are S/N 4313, which is a VERY rare S/N to find and some people feel that these have more bass than the 10XXX models. The last pair on eBay in the 4XXX sold for $3,206.95 USD. They should appreciate more than most you see with the wooden boxes. Unlike other headphones, these use no acoustically hard components, which enables the sound to interact more freely. What truly makes these one of a kind is the fact that they're equivalent to wearing speakers on your head (hence the speaker tap adapter cable they include). They require a lot of power, which is why we upgrade the adapter cable. The speaker enclosure uses a vibration-free diaphragm that is driven by a magnet system to minimize any interference or distortion and really provide a personalized listening experience. The speakers actually open and close using adjustable hinges and the hinges and locks both work very well. Many used ones you find, will have one or all of the locks not working. By opening and closing distance to your ear, the sound will change. Unfortunately, I don't have the manual, case, or original speaker extension adapter anymore, but I feel that both the custom speaker adapter cable and the case are much better than the original. The case is a brand new Pelican 1400 which we custom fit for the AKG K1000s. The case was purchased less than 1 month ago. There is a link to the manual on their website if you search for AKG K1000 on Google. Please don't hesitate to ask any questions. $1,650 via PP. I will pay shipping in CONUS; Buyer pays PP fee or via F&F.
  11. Thanks, I didn't think you had to be but who knows. Doesn't seem to be enough activity to warrant a fee.
