  1. Further information: Excellent condition, comes with two leads, one straight (shown) and the other coiled (not shown - has never been used, but will be included). Both leads have gold plated 3.5 mm/6.3 mm adapters The headset will be packed and posted in the original box. Great sound, based on the Sennheiser 600/650 models, but way better. Plenty of deep bass without being boomy, no sibilance, but plenty of top end and a realistic reproduction of vocals - as J. Gordon Holt said, "Get the midrange right and all else will follow". Reasonably easy to drive at 110 ohms impedance and sound magnificent being driven by the Burson Audio Conductor Reference 3X.

  2. Hi Ralph, it's still available and comes with an standard aluminium Apple remote that basically can control volume. John Buchanan
  3. Burson Audio Conductor 3X review. This brand new Burson Audio Conductor 3X replaced a Mytek Digital Stereo 192 DAC and is being used to drive a Beyerdynamic T1 Gen. 2, a Neumann NDH-20 or my wife’s AKG K701. Sources are from a Pioneer Blu-ray drive via a Surface Pro 3 and Surface dock. Physically, the Conductor 3X is a beautiful piece of high quality, superbly constructed and magic sounding premium gear. May there be more Australian gear produced at this level, rather than the old “it might look as though it was made with tin snips, but it sounds great” excuses for sub-optimal presentation. The only complaint I’ve heard so far (from a few user comments) is that the included USB-A to USA-C input cable isn’t enabling consistent connections. Spend $40 and get yourself a high quality replacement before your Burson set arrives. I’d suggest Burson invest in a run of ultra high quality cables and send one each out to all purchasers of the Conductor 3/3X free of charge, IMHO. That’s it for flies in the ointment! The software provided is easy to install and works faultlessly on the Surface Pro 3, enabling CDs, DVDs and Blu-rays to play without the occasional manual fiddling that was necessary for the older Mytek. The Burson simply works as it should – automatically adjusting to the supplied sample rates without fuss The sound of this unit has really surprised me in comparison to the Mytek. Whereas the Mytek could sound a little thin and strident and appeared to overload at higher volumes leading to distortion on John Farnham’s vocals on “Full House”, the sound is transformed on the Burson Conductor 3X. It’s far smoother, with a much better bottom end and there is absolutely no distortion on Farnesy’s vocals now – the vocals are smooth as silk without the previous “bubbly” vocal distortion. The dynamics appear to be limitless (as they should, given the enormous power of the amplifier section), yet there is no audible residual noise when music isn’t playing. No doubt, this is due to the external digital MCPS power supply. I haven’t tried the 4 pin XLR output as yet – just the 6.35mm single ended output, which appears to be more than adequate for both the Beyerdynamic and the Neumann. The Beyerdynamic T1 Gen. 2 sounds like it has been transformed into a different headphone now – seamless left to right, loud to soft with a rather pleasing reduction of the accentuation of the lower treble/upper midrange peak that was far more apparent with the Mytek. I’m not good at hearing headphone depth in the sound-field, so I don’t feel qualified to say anything there. The only time I’ve ever been fooled into hearing a 3D sound-field was through my Stax SRM-Monitor (an electrostatic headphone amplifier and diffuse field equalizer in one beautiful package) and Lambda Nova Signature combination listening to the Stax’ Space Sound Binaural CD, anyway. With better recordings than “Full House”, it’s like walking through the door of the Apollo Command module, sitting down and launching into space. For example, Miles Davis’ “Kind Of Blue” – the string bass sounds deep and natural, the drum dynamic - strikes appear instantaneously and disappear just as fast as the sound decays naturally. It sounds a step closer to the fabled Columbia master tape, without the amp “hanging on” to anything that shouldn’t be hung on to. Chick Corea’s “Super Trio”, now sadly out of print, captures the dynamics of Steve Gadd’s drums effortlessly – cymbals to bass drum, the deep bass and finger plucking of Christian McBrides double bass naturally and the singing and sobbing of Chick Corea’s grand piano with dynamic ease and tonal accuracy. You’ll want to play this sonic and performance treat again and again. As Molly Meldrum said, and I’ll repeat his words with sincere meaning here, “Do yourself a favour” and buy the Conductor 3 (for a single ended system) or the Conductor 3X for a balanced system. I’m not one for superlatives, but here I am, laying the “best I’ve ever heard” challenge down. Congratulations Alex and Burson Audio – you’re right up there.

  5. Ordered the 3X conductor. Hopefully, it will be here for Christmas.
  6. Item: Beyerdynamic T1 Gen. 2 headphones Location: Margaret River, Western Australia Price: $950 ONO Item Condition: Excellent - no scratches, dints or scrapes Reason for selling: Too many headphones Payment Method: Paypal Only Extra Info: These headphones have been very gently used in a non-smoking, no pet household. The design brief was to reduce the brightness and increase the bass, compared to the original Beyerdynamic T1. The leads to the earpieces are now detachable, compared to the previous model - this allows different cables to be used if you so desire. Includes the original, fabric covered OFC cables, and the hard clam-shell carry case. New selling price is approx $1300 on Ebay. Ebay handle is buchanan55 if you want to check my trading profile there. Photos: Advertisements without photos of the actual item will not be approved.
  7. Further listening - these are really excellent headphones - brass sounds as it should - i.e. if heard live - it has midrange impact/bite without that horrible glare that piggybacks so many headphones' reproduction of brass. This carries through to vocals - good control of sibilance - the spray can effect has been minimized. Bass - deep, not boomy or resonant. Just what should be there. Neumann really has jumped into headphonia with a genre leading product - they appear to have said "enough" to the ever increasing "clarity = more brightness" tendencies of modern phones, without losing the clarity. These get an A+ rating
  8. Had a bit of time to get a handle on the new Neumann NDH-20. Starting at the bottom end, they have a rather nice, but not excessive bass response - it's deep and well articulated. The bass drum also appears to have almost feelable impact, without boom. The midrange is mostly slightly recessed (compared with the Beyerdynamic T1 Gen. 2) which appears to give the sound less detail initially - however the detail is there, but not as bright and accentuated as the Beyerdynamic. Treble is present without any nasty bright surprises - not too bright nor dull - just right for me. These phones appear to be quite efficient - they play well from the Mytek DAC 192, but scale up well on the Phonitor. The finish is simply beautiful - even better than the Beyerdynamic T1 Gen. 2 I don't feel I'm missing anything from these phones, nor do they have any exaggerated frequencies. They sound like they have a flat frequency response, without measuring flat, and they certainly aren't boring.
  9. Thought I might take one for the team and order these new closed back phones from Neumann/Sennheiser. Should be interesting compared with the Stax Lambda Nova Signature/SRM Monitor or the Beyerdynamic T1 Gen.2/SPL Phonitor combinations.
  10. Nice amp, Rickus. That would be my dream amp for the Stax.
  11. Rickus, It will sound much the same as playing them through an SRM 1 Mk 2 Professional amplifier - if it had balanced inputs - until you turn on the diffuse field equalizer, which is optimized for Stax Lambda Professional phones (I use it with a Lambda Nova Signature). It sounded excellent with the Stax Sigma Pro and the SR-007 Mk1.
  12. Hi F18, not sure - I have a couple of dynamics already here (Beyerdynamic T1 v 2 and the AKG 701) and a Mytek DAC and an original Phonitor to drive them. Surprisingly, after what I read about a lack of bass with the K701, they have plenty and sound great with both the Mytek and the Phonitor. With that in mind, I was after an AKG K812, but in no rush to depart team Stax. If no interest is shown c'est la vie - it will then remain at Casa Buchanan.
  13. Item: AKG K812 headphones Price Range: Max $1200 Item Condition: New or ex-demo Extra Info: I'm after a set as close to new as is feasibly possible. Payment via Paypal Please don't forget to report your post as FOUND when possible. (You can now delete this text).
