  1. Device To Increase Impedance of Speakers

    Yes, I have updated the WTB ad to be clear I need a pair.
  2. Device To Increase Impedance of Speakers

    Thanks. I have now posted a Wanted To Buy ad looking for a used autoformer:
  3. Device To Increase Impedance of Speakers

    That's the one! Has anyone used an autoformer, and if so what sort of difference to the sound did you notice it made in A/B testing? I would like to try using a regular (i.e. not high current) amplifier that I'm interested in on my Duntech Sovereign speakers, but the amp would likely be fried without a device like this to increase the speaker's impedance dip in the bass frequencies.
  4. I once saw online a device that can increase the impedance of low impedance speakers so that you can drive such speakers with regular amplifiers. It was claimed that the device - installed on the speaker wire between teh amplifier and the speakers - does not affect the sound. I believe the product had a very specific name (not just "resistor" or similar) and I have forgotten the special name of this product/device so I can't find it. Does anyone know what the device is called? Anyone used one?

  7. Item: Triad Bronze/4 LCR In-Wall Speakers Location: S.E. Qld Price: $1,150 ONO Item Condition: Excellent 9/10 Reason for selling: Not required as decided to use floorstanders instead Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Triad Bronze/4 LCR In-Wall Speakers. Can also be used as freestanding. Suitable for small to medium size media rooms (the Triad Silver and Gold speakers give the same sound quality but are more suited to larger rooms).The set includes three speakers for Left, Centre and Right channels in a surround-sound setup.As well as in-wall, these speakers could also be used in cabinets or even as stand-alone speakers if necssary.These hifi speakers are highly recommended by home theatre hifi speacialists and installers.They have had very little use and are in as-new condution both cosmetically and functionally. Grilles not included, but can you can buy these separately from the distributor and I will factor this into the price. Will double-box and then courier them Australia-wide at buyer's expense (negotiable).Cost over $3,000 new, will sell for a third of new price.Manufacturers information & specifications: http://www.triadspeakers.com/products/home-cinema/iw-bronze4-lcr/ Pictures:

  9. Recommended in-car stereo system

    As always the speakers will make way more difference than the electronics. Second and last area that makes a huge difference is acoustics... I would investigate digital "room" correction for car audio if looking to make a really significant difference through electronic means: https://www.dirac.com/live-automotive/ Personally I think all the amplifiers/receivers you mentioned will most likely sound fine. Blind test the sound of the most expensive and cheapest to see if you can pick the better sounding one reliably... if not, buy the cheapest. Sent from my iPad using Tapatalk
  10. Yep, well spotted. They sound very good to my ears, especially for the price they go for secondhand these days. Sent from my iPhone using Tapatalk
  11. Cost benefit is a factor in this. Yes a wooden box would be safer, but the cost to get a cabinet maker or similar to make one would at least double the shipping cost for speakers this size and make unviable. The seller in this case would not be in a position to make one. Putting on a skid would offer minimum benefit for the short trips to their local warehouse. Also the insurance would have covered major damage, so you can go overboard with the packaging when you're already insurance covered for less cost. Most importantly, it's like a good careful removalist can avoid damage with minimal packaging/protection. Likewise sensitive freight companies like TSS take way more care and have a completely different distribution system to a general courier company like TNT or E-go, and even if they were in a wooden box I would not be 100% sure there wouldn't be damage with such companies. Sensitive freight companies offer a good service to package goods where the seller can't or won't package them. I would have no hesitation to use them again, but I'd get shipping insurance just in case. Sent from my iPhone using Tapatalk
  12. The Duntech Speaker Thread

    Maybe he means the Crown Prince / Princess and their big brother the Sovereign are a step above other Duntechs??? I have heard the same said elsewhere. They probably all represent good value for their current used prices though (if you've got a nice powerful amp to run them). Sent from my iPad using Tapatalk
  13. Lyngdorf TDAI-2170

    I have read that the amp gives a high dynamic range presentation (I think Langford himself said they can achieve 20dB more dynamic range than competitors with this amp). Is this something you have noticed, if so is it obvious compared to traditional amps you've heard? Also they say it sounds significantly more dynamic at low volume than other amps. This is something I normally associate with highly efficient horn speakers. Again is this something you've noticed? Has anything really disappointed you about the sound of this amp?
  14. The closest current stereo amp from Parasound appears to be the A21 model, but looking at internal photos it looks very different inside. My understanding is the JC1 as the flagship amplifier was designed as a monoblock, and designed to be able to drive very low impedance speaker loads. Even their A51 5 channel amp is rated at less than half the peak amps in their specs.
  15. Item: Parasound JC1 Monoblock Amplifier (single only, so you can use it for a centre channel or buy another one for stereo) Location: S.E. Qld Price: PRICE DROPPED TO $3,250 Item Condition: As new functionally. Very good cosmetically. Reason for selling: Decided to use old ME amp instead. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: This silver colour JC1 single monoblock amp only has around 12 hours use on it so not even run in yet. Cosmetically perfect apart from a couple of very small scratches which I only just found when photographing it closely in strong light. I have made them look obvious for the close-up photo here, but from normal viewing distance they are very hard to spot. This sale is for one monoblock only, so you can use it as an awesome centre channel, or buy a second one elsewhere for stereo. Awesome amp very conservatively rated at 400 watts into 8 ohms, 800 watts into 4 ohms, 1200 watts into 2 ohms, and 135 amps peak current! Cheapest I can find one for worldwide at present is over AUD$2,800 and that one's obviously a lot older and in very poor condition. The one I am selling is almost new. Cheapest at the moment in Australia is a pair being sold on Gumtree for equivalent of $3,950 each and they are older and not in as good condition cosmetically. See link: https://www.hifishark.com/search?q=jc1 I will double box it and can make suggestions for shipping and insurance which will be at buyer's cost. Parasound JC1 is currently a Stereophile Recommended Component Amplifier (Class A): https://www.stereophile.com/content/2016-recommended-components-power-amps Parasound Halo JC 1 monoblock: US$9000/pair $$$ ★MF heard exactly what this high-power—400Wpc specified, 586W at clipping!—John Curl-designed amp's specs showed: "ultra-wide bandwidth, high-current capability, low, low noise, a high S/N ratio, and a fast slew rate, among many other indicators of outstanding amplifier performance....There was an honesty to the overall tonal and harmonic presentation that transcended technological stereotypes." MF found the overall sound to be powerful, refined, smooth, organized, dynamic, transparent, and rhythmically supple, if a little on the subtly warm and rich side of the sonic spectrum, but decided that this not at the expense of transient speed and resolution of detail. "Perhaps some listeners will find the JC 1 too refined and perhaps a tad polite, but I didn't." "Rocks for sure," says ST, adding that with the amp driving the Triangle Magellans, he found the "bass firmed up, the sound wasn't strained in any way, and there was an overall sense of ease. Dynamic ease. Listening ease. Just ease. Compared to the Halcros, the Parasound JC 1s brought the soundstage forward. Tonally, the Parasounds were magnificent?with no trace of solid-state hardness. And the amps weren't even broken in." "The Parasound JC 1 is one of the finest high-powered solid-state amps I've heard," said ST. "Think of it as a 25W class-A amp that does 400W class-A/B when pushed." Matched with the JC 2 preamp, the JC 1s presented even greater holographic detail and transparency. The Parasound Halo JC 1 traded the Moscode 402Au's snappy, vivid tonality and larger soundstage for "quiet precision," clarity, and focus, said WP. The Halo JC 1 traded the Aesthetix Atlas's creamy midrange for greater bottom-end heft and top-end extension, said WP. Compared to the Bryston 7B SST2, the Parasound had deeper bass, tighter images, faster transients, and greater low-level resolution and microdynamic delicacy, said MF. A favorite of JA's, who was equally impressed by how the JC 1 performed on the test bench: "This is excellent measured performance. The Halo JC 1 is not only the best amplifier to come from Parasound, it ranks up there with the best high-end heavyweights," though WP felt that while the Halo JC 1 exhibited grace and delicacy compared with the much more expensive Luxman B-1000f, it lacked some impact, drive, resolution, and detail.
