@Eagleeyes To my knowledge such an adaptor does not exist. Though if you have the pinouts for both ends I can have a cable custom made with the terminations in any configuration.

@mjth Hi Matt, For the DAC in questions and for sale in this thread: DiDiT DAC212SE The I2S/HDMI connection will in fact work with gear wired for the PS Audio standard. However you will need to reverse the analogue output connections since Left and Right will be swapped. To mitigate this and to get 100% compatibility the HDMI Pin7 and Pin9 need to be swapped. I can supply such an adaptor made by the manufacturer at no extra cost to you. This will take a little time to get delivered but the above L+R output switch should work fine in the interim. Mark

If your receiver/pre amp has a sub out, then it's a mono out and all you need is a single cable. If your pre only allows stereo out then you need to provide the stereo signal to the sub that will then sum the signal to mono.

It is a single cable intended for a single subwoofer. Mark

Since there is no real I2S standard the I2S is causing many probs for all. Even when pinouts are supposed to be compatible sometimes they don’t work. So I am waiting for the manufacturers confirmation and may take a few days to make sure there is a good solution to avoid problems. The DAC212SE (in this thread) is almost pin compatible and we should be able to get full comparability with an adaptor, though work still ongoing to check what is not pin related behind the scenes.

@mjth clarification still pending! Sorry for the delay... I2S is quite complicated but I will get back as soon as I have accurate information. Mark

Hi Matt, Thanks for the compliment on the DAC at the show. It really is quite special. I am travelling in Vietnam and Indonesia at the moment, my apologies for slow response. I need to get a response from the manufacturer to be certain that I'm giving you accurate information. Thank you for your patience. Mark

Item: DiDiT DAC212SE DAC/PreAmp/Headphone Amp Location: Melbourne Price: $4495 (saving of $2480 off the RRP of $6975) Item Condition: Ex Demo Payment Method: Bank transfer, PayPal Extra Info: As new condition. Includes remote, XLR-RCA adaptors and original packaging DiDiT DAC212SE State of the Art Digital to Analogue Converter, Preamplifier with input select and Headphone Amplifier. Fully remote controlled. True Differential Output-stage Double CMR at each halve of the circuit Differential in > Differential out No inverters Made in the Netherlands Tonal accuracy The DAC212SE is probably the most intelligent digital pre-amp available today. Quite simply the perfect integration of audiophile technology and intelligent software. The unique software lets you configure the DAC212SE to suit your needs and requirements, without degrading the audiophile performance. Every effort has been made to keep the signal path short and a very compact circuit with only the most essential components to guarantee the best possible performance. The DAC212SE uses a fully balanced internal architecture, and all the benefits of a balanced design including Common Mode Rejection (CMR) are fully utilized. Audiophile Technology A true differential design allows the opportunity to design the signal path as a tightly coupled pair. This implies that the two magnetic fields partly cancel each other out, which results in a lower inductance design. In turn, this contributes to lower distortion and a purer signal transmission. True Balanced Design There are several ways to achieve a balanced or differential output. The DAC212 incorporates a not very common true differential circuit combined with “Virtual Grounding and balanced interfacing” this results in a very clear signal, free from interferences and conveying the music in its purest way. This requires very advanced 4-layer PCB design. While only true balanced circuits are superior to single-ended designs, they are sparsely used (even in high-end audio) due to the extra amount of components. In our balanced design we take this even further, as the entire output section is true differential. Thereby gaining double the CMNR benefits compared to regular true differential design. The effect is unsurpassed musical performance! HD audio compatible the DAC212 was designed to accept almost all high resolution standards of digital signal. Regular PCM up to 192kHz via the SPDIF inputs, and 384kHz and DSD512 via USB. It will easily connect to your Roon endpoint or any other digital source. Audiophile Headphone output The DAC212SE is fitted with a very powerful output stage that drives any headphone with ease. The low impedance output stage is capable of delivering an enormous amount of power. While maintaining absolutely stable under all conditions. No additional headphone amplifier required!

The capacitance between inner conductor and screen is maximized using a very thick inner conductor. To further increase capacitance LDPE thermoplastic is used as insulation. The result is a staggering 128 pF/m. This cable design ensures you can run long lengths without signal degradation. It is therefore no problem to place your subwoofer(s) optimally in the room where system integration and sound quality is best. The triple shield constructed from a double, reverse spiral wound sheath and the LDPE semi-conducting layer shields the massive inner conductor.

Each of the six main conductors are further divided into six sub-conductors with an air tube at the centre of each sub-conductor. The six sub-conductors are paired two by two with each pair having different properties. This is to ensure optimum conditions throughout the entire audio spectrum, with the high frequency carriers being silver plated, mid frequency carriers are tin plated and pure copper is used for the bass. The sound is lifelike and natural with breathtaking spatial separation and precise placement of instruments. AIR One of the most ideal insulators we know of is air, and this is why it is so extensively used in this top of the range cable. 10 specially arranged air pipes separate each of the inner conductors, greatly reducing the capacity to only 98pF/m. This state of the art nearly loss-free transmission of audio signals results in impressive sound, even over long distances. The SC-6 AIR Silver speaker cables are manufactured with ViaBlue T6s pin (banana) plugs. A soft banding and a flexible satin mat sheath protect the entire cable system.

A novel idea... so it would seem 😎 https://hackaday.com/2019/05/02/kicad-gets-banana-for-scale/

To get the chest thump you do need a considerable amount of SPL. Something that home speakers are generally not designed for. At least not without high amounts of distortion and more importantly large compression. To get the crisp 'snap' of the drum kit, including the bass drum you need enormous dynamic range in the 100-500Hz region. This has little to do with the subwoofer when talking HT. Any reasonable recording will be good enough. You don't need a live band hooked up directly to get this chest thump and snap. The room comes into play. With a single subwoofer, your typical frequency response will be full of peaks an nulls making the bass sound limp and swampy. With two well-placed subwoofers, the problem will be halved. A third well-placed subwoofer can tighten up the bass tremendously to outperform a single sub by a large margin. large and lightweight cone. This is completely contrary to most home speakers, that achieve reasonably deep bass from very small enclosures. It's a tradeoff. The laws of physics are quite clear on this. Add mass to get bass extension, power handling and compression will suffer. Sure, we can design extreme excursion drivers and huge amps to somewhat compensate, but compression and impulse response is no match to an efficient design that all things equal, will be physically huge in comparison. @Marc describes his experience with a large efficient speaker very well earlier in this thread. Practicality and personal preference are of course large factors in all of this. /Mark

I have looked into this further. The track in question was Mahler: Symphony no.1 "Titan" 2nd movement, by the Royal Philharmonic Orchestra, Prague Symphony Orchestra, Slovak Philharmonic Orchestra, Vienna Volksoper Orchestra. It is from a Classical compilation and unfortunately it is not specified which Orchestras perform which tracks, so take your pick? /Mark

@rantan I happen to have a pair for sale! /Mark

Thank you all for your kind comments and contributions. The HiFi show was a great success with many commenting about their favourite room. That makes me really proud and solidifies that my own ideas and ideology about speakers and equipment are indeed shared by the Oz HiFi connoisseurs 🙂. The Melbourne Audio Club invited us with open arms and the feedback what again overwhelmingly positive. I personally loved, when the presentation was over, how most members rushed to the front to get a better look and ask relevant questions. Very fulfilling 😎 . /Mark
