  1. Item: DEQX Pre-Mate Plus (Silver) Location: Perth Price: $3500: Exchange for Black Pre-Mate Plus, HDP-4 or HDP-5 give or take $ as appropriate Item Condition: Excellent with original box, remote looks a little untidy due to sticker coming off. Reason for selling: Got a used one to try out, it's amazing, the rest of my gear is black though. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: No introduction required, if you are looking at this then you already know what it is. I just want a black one.... If you have any of the above models in black and want a silver Pre-Mate Plus then let me know so we can arrange something! The remote on my one looks a little tatty, but they all use the same one anyway, so I'll just keep my one if you prefer Photos: Advertisements without photos of the actual item will not be approved.
  2. Item: Meridian DSP5200 + DSP5200HC + G68 (high gloss black speakers with silver processor) Location: Perth WA Price: 12k ono Item Condition: All in great condition, some swirl marks in the gloss though no scratches Reason for selling: Home renovations Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Meridian needs no introduction in the digital active speaker market as these guys are the pinnacle. This is an outstanding system and will be sad to see it go, but my loss is you gain. Retails at over $40k and the speakers are still a current model. Original boxes, cables etc. Will upload some more images as soon as I can. Prefer local sale. Photos: Advertisements without photos of the actual item will not be approved.
  3. Item: MiniDSP 10x10HD Location: Adelaide Price: $600 (plus postage) Item Condition: Excellent Reason for selling: Have purchased another DSP Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: I've been extremely happy with this unit. I read some comments about the noise floor on some MiniDSP boards but have to say this was near silent on my four way horn system. As long you have your gain structure set up correctly it's a non-issue. I'm really only selling because I've purchased the new DAC8 DSP from Okto Research to experiment with FIR filtering. This item is in excellent condition both aesthetically and functionally. $600 price on miniDSP 10x10HD unit only. Will require 12v power source. I have a good quality DB25 to 6 x RCA cable (see pics) I can also include for an additional $50. My Okto DSP came in a very well constructed padded carton (see pics) that I can repurpose for this item should an interstate buyer be interested. NOTE: This is still a current product so all the specs can be found on the miniDSP website. Photos: Advertisements without photos of the actual item will not be approved.

  5. Item: HEAVILY MODIFIED BEHRINGER DCX2496 Location: Adelaide (happy to post to other states) Price: $795 plus postage (no offers) Item Condition: Excellent condition physically and functionally Reason for selling: Needed more channels Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: This unit has been professionally modified by Selectronic in France. It has had their full suite of upgrades implemented, which cost over €1000. For a detailed exlanation of these upgrades, see the page on their site (I've translated it into English via Google Translate): https://translate.google.com.au/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.selectronic.fr%2Fdcx2496-modifie-par-selectronic.html&edit-text=&act=url I was extremely happy with this unit. It sounds absolutely superb. And if it only accommodated 8 outputs instead of 6 I would definitely still be using it! Item is in excellent condition inside and out and performs flawlessly. PLEASE NOTE however, that these modifications render the auto time alignment feature inoperable. This means you'll need to take your own measurements and calculate your own delay if you're using the time alignment function. (A superior technique in any event.) I have the original carton and manual, so can post to anywhere in Australia. Pick up from Adelaide CBD is also an option. Pictures:
  6. (I just try this in this section of the forum too. I don't know where it will fit in the best.) I just recently started experimenting with JRiver doing all the audio decoding for movies instead of using bit stream. This will open up the possibilities for using convolution filters/room corrections. My reciever can't do any room corrections/convolution filters and doesn't allow me to set the speaker distance for induvidual codecs, unlike the speaker size and level settings, which I can set for induvidual formats. So I cannot bypass the reciever's dsp in total for some A/B testing. Does anyone have any experience with using DSP equalizer or convolution filters in JRiver. My firts experiment will be to find out if I can make the center speaker less localized or virtual lift it to the same height as my L+R speakers. It is sitting lower and I am able to pick it up. I would like to have it blend in more with the L+R speakers. The other thing is, does anyone know about HDMI drivers that bypasses the Windows Audio Management. I am currently using a Nvidia GeForce WASAPI audio driver.

  8. Just stumbled onto this page that demonstrates a very comprehensive objective (as in measurements not as in audibility) comparison of a variety of upsampling filter implementations. http://src.infinitewave.ca/ This is probably of more interest to graph nerds but I think it's pretty interesting and wanted to share. It also gives some insight into vendor claims about the filters used in their software/hardware. It does only demonstrate non-integer multiple upsampling which represents a worst case, for most of us here it's unlikely we'd ever do anything other than a direct multiple resample. Chris
  9. Dastrix and myself have been doing a lot of work on power response EQ and modal EQ lately, and we came across an aspect which I thought might be of interest for others here: The room we are looking at has a symmetric setup of the boundary walls and the speakers, but very disimilar acoustic properties on the left and right sidewall. Aesthetics dictate that nothing can be done about this. Listening to the left and right speaker individually, one finds a huge difference in the spectral balance. ETC measurements around the listening position (LP) show strong differences in the strength and timing of the early reflections between left and right speaker. The room impulse response (RIR) also shows that both speakers experience very different acoustic radiation impedance both in the modal and in the transition region. Ergo, the differences in balance are clearly apparent from measurements. We attempted to fix this balance problem. The minimum phase filter design was done using power averages of measured RIRs around the LP. We applied different time domain filters as recommended by various researchers to separate the perceptually relevant early part of the RIRs, and designed two sets of filters: one set based on power average of the RIRs from the left and right speaker seperately set based on the power average of the RIRs from both left and right speakers Due to the reasonable symmetry in the modal region, there were no significant differences between these filters. Things changed in the transition region - here the filters differ significantly if designed for both speakers individually. Some differences were apparent in the statistical region, but they were deemed reasonably small as to make a significant difference to the spectral balance. No matter what type of time domain filtering we employed, the spectral balance between the speakers always got worse if we used filters designed for each side individually. The balance issue always became the dominant factor when assessing the perceived quality; any improvement gained from the filtering was masked by the unbalance. The filter designed for left and right power averages instead performed very well. The balance issue remained the same, but the filtering improvements suddenly dominated the perceived quality. We learned three things from this: Firstly, strict symmetry is the key to good reproduction quality. The room we were loking at will require some tricky treatment or a rotation of the setup to improve the balance issue. Secondly, the time domain filtering approaches we tested were not capable of correctly representing the perceived spectral balance. More literature review is needed. Thirdly, when designing power response EQ and modal EQ for systems with notable spectral balance issues that arise from asymmetric acoustic boundary conditions, use power averages of both speakers as the design basis. Otherwise you exxagerate the balance issue and unwillingly reduce the perceived quality by introducing distraction.

  11. G'day I'm just come across this new article at Hifi zine It's about using a Mac to setup & run an active 2-way with a sub What we can do with a PC Mac in 2013 is quite impressive It aint no good to me coz I'm mot a MAc guy, so I use MiniDSP, but an impressive article all the same. http://www.hifizine.com/2013/06/pure-music-fabfilter-proq-active-speaker/ Graham
  12. Item: Audio gd DAC19 DSP-SOLD Location: Adelaide, Australia Price: $400+shipping and paypal (not even joking)- SOLD for $450. I couldn't refuse the offer which was given to me. Item Condition: cosmetically and electronically mint. May have a bit of wear around the connectors, as expected of used goods. Reason for selling: To fund a new setup Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Up for Sale is an Audio-gd DAC19DSP The AudioGD DAC19 is a great DAC which has been touted as being worth twice its actual value and is one of those well kept audio secrets. This is perhaps why its a discontinued product, being too expensive to produce for AudioGD with 2x BurrBrown PCM1704UK DAC chips being its crowning jewel. Only the reference series DACs remain that use the PCM1704 (costing 1100 and 2000 respectively), with wolfsons and Sabre designs being put in the large hole left by the DAC-19 series. As some of you may know, the PCM1704UK is one of those last true multibit DAC chips with the recent takeover of Sigma Delta designs and discontinuation (or limited production) of PCM1704 multibit silicon. Sourcing the 1704 chips is difficult and expensive, with prices on ebay alone at 56 odd dollars apiece. However, the prohibitively expensive Naim, Mark Levinson and Wadia DAC's still use the 1704 which in itself attests to the superiority of these chips. That isn't to say that the supporting electronics doesn't support the potential of these chips, as the overbuilt power delivery system really does allow this DAC to sing. Just search for internal photographs of AudioGD products to see for yourselves. The item itself is in mint condition without any scrapes or scratches. Needless to say it is in great cosmetic condition and is also fully functional. I have had it for a year and the previous owner who purchased it brand new owned it for 6 months beforehand. It pains me to see it go at 500 let alone to the significant price drop to 400 dollars. (sold for 450) As i'm a new SNA member, it may be difficult to trust me especially as I'm selling an item for a price which may appear to be a scam. However I do have trader feedback on Head-fi. My username there is stainless824 and you will see the same classified placed on there also. The americans just don't know what kind of deal they've got in front of them. Pictures:
