  1. The ones above have been painted black by someone, they have the incorrect tweeter, they have had aftermarket crossovers installed (which are not better I have tried some ) , thats what we know. there may be more modifications as someone has had a good go!!. These below have the correct drivers a refurbed crossover done by duntech and a new cover (which can be easily changed to your preferred colour if the current is not your style) same price, same internally. I know which I would go for.
  2. Item: Vintage Proton receiver + free cassette deck Location: melbs Price: 150 ono Item Condition: good Reason for selling: clearing the decks Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Bought this many years ago for a second system , now long gone, receiver working brilliantly but the cassette deck has an intermittent issue which requires opening it up to fix which is doable but annoying . Proton was the oem manufacturer for NAD amongst others. It seems they had borrowed some design from them. Tuner in the receiver designed by Tom Schotz. Cassette deck has dolby B C and plays metal. Nice 2 head deck . more info from online http://www.hifi-classic.net/review/proton-930-494.html The Proton 930 stereo receiver combines a high-performance FM tuner section designed by Larry Schotz with an amplifier capable of driving load impedances as low as 2 ohms at high power levels without damage or excessive distortion. It is rated to deliver 30 watts per channel into 8 ohms. There is an "anti-clipping circuit" designed to reduce the audible consequences of waveform peak clipping and a bass eq circuit to correct for the bass-response limitations of many compact speaker systems. Dimensions are 4 x 16-1/2 x 9-3/4 inches, weight 15-3/4 pounds. Price: $360. LAB TESTS The Proton 930 demonstrated an exceptional output-current capability. Its measured 1,000-Hz output power at clipping was 44 watts into 8 ohms, 63 watts into 4 ohms, and 66 watts into 2 ohms. Its dynamic power output was even more impressive: about 54, 78, and 130 watts into 8, 4, and 2 ohms, respectively. Clearly, this is no ordinary "30-watt" receiver! Our test unit, an early production sample, lacked a final instruction manual as well as any of the pertinent performance specifications other than rated output. In a way, this made our tests more interesting, since each measurement showed this to be an even more unusual receiver than we could have expected. The amplifier distortion of the Proton 930 was not only very low, but it remained low over the full audio range and at any power level up to the clipping point. The noise level was exceptionally low, the phono preamplifier overloaded at the same high level of 210 millivolts over the full audio range, the RIAA equalization was highly accurate and unaffected by cartridge inductance, and so on. The amplifier did shut down as we approached the clipping level when driving 2-ohm loads. An audible click and lapse of a few seconds before the amplifier returned to service suggested that there was a thermal protection system in operation. We were especially interested in the FM-tuner performance in view of the acknowledged talents of its designer and our previous experience with his products. We were not disappointed. The measured sensitivity was high, and the noise level was as low as we would expect to find in any competitively priced receiver or tuner. The distortion in stereo was very low-lower, in fact, than we can recall having previously measured in an FM tuner. In only one respect did the FM tuner's performance disappoint us. Its image rejection was so unexpectedly low at 40 dB that we suspect it was only a defect in the early production sample that we tested. The selectivity of the Proton 930 was among the highest we have ever measured: 96 dB for altemate-channel spacing and almost 16 dB for adjacent-channel spacing. This was even more noteworthy in view of the tuner's low distortion, since distortion usually must be traded off for high selectivity. Capture ratio and AM rejection were both much better than average. The stereo channel separation was more than adequate and quite uniform. The front-panel LED signal-strength indicators were well spaced, coming on unambiguously at input levels ranging from 23 to 72 dBf (when at least three lights are lit, the full tuner performance is realized). Even the AM tuner had a better than average frequency response, flat within 2.5 dB overall from 26 to 3,300 Hz and down 6 dB at 4,000 Hz. COMMENTS The Proton 930's anti-clipping circuit causes the waveform to clip more "softly" than is usually the case. Though in theory this is desirable, we are not necessarily convinced of its practical benefits. We prefer to operate an amplifier well below clipping, and the power reserves of the Proton 930 make clipping even less likely than with most receivers of considerably higher continuous-power ratings. But as far as we can tell, the circuit does no harm and has no detectable or measurable effect below the clipping point. Pictures:

  4. Agree it can happen in the short term, but over time a winner emerges for me They change as your listening matures just like your appreciation of wine matures. Things have changed a lot less as i get older. Your taste at the time is exactly what you should follow as it will enhance your listening experience. If you listen to what is "ordained" to sound best you may end up listening to less music. Sometimes I end up taking a sideways move or even backwards but I endup working it out. If you measure your "progress" by how much time you spend listening to your stereo and how much you enjoy it its easier to navigate. Audio nirvana happens periodically when your stereo meets or exceeds your expectation at the time. It is a solitary thing and no one elses opinion counts at the time. However your expectation changes over time so its not easy to meet it over an extended period. I am positive my setup sounds better than any of the previous iterations.
  5. Not sure if you are but are you suggesting as long as your streamer is "immune" the rest upstream doesnt matter?
  6. Understand and respect that. But I still dont know what to look for and will use things already mentioned and perpetuate the hi priced bs product. What about discussing more broadly the characteristics of a well setup streaming rig with a focus on the network side ie modem- characteristic a b c, cable abc router, abc, server abc which gives me/us a better chance of finding something that is more likely to work well. The kinds of characteristics that might be found in specifications would be best (or something else?). Is that doable?
  7. Could you please list the model number
  8. Thanks for that Its a good review and I agree with just about everything they say, They say "The amplifier behaved as expected closer to its power limit (THD+N at 1%). This time, the values we got were 300Wrms/8-Ohm and 430Wrms/4-Ohm. With a power increase factor of 1.43 and the ability to offer such power levels, RΙ-100 appears to be more than capable to drive any demanding loudspeaker. " The FBI stereophile review says "The FBI is specified as being able to deliver 300Wpc into 8 ohms (24.8dBW). However, plotting the output power against the THD+N percentage (fig.3) shows that the FBI actually delivered 430Wpc into 8 ohms at 1% THD, which is a significant 1.6dBW higher. With both channels driven, the amplifier clipped at 667W into 4 ohms (25.2dBW). This is a ratio of 1.55. The Krell does a little bit better and is probably due to its much more substantial power supply The doubling power thing is a bit of a myth which the manufacturers perpetuate by underquoting the 8 ohm figure. So the Krell is actually a 430w amp. It is also class A. It is a Beast!!! and I would love to hear it! For the record my speakers are notoriously difficult to drive but are 90db efficient . Dont feel like the Vitus has come close to running out of puff on even torturous tracks but I dont doubt your experience. It just shows again how it can be risky to rely on reviews or measurements to tell you how it will work in your system.
  9. Looking at the description he has taken it from the epitome tower website so the whole ad is a crock-o-shtimpy
  10. The one on ebay is an eclipse not the epitome, Bass driver is too small and wrong colour.
  11. Be interested in the reviews as I cant find anything with measurements on the ri-100. The stereophile review measured The FBI at 430w into 8 ohms. It has a 3000VA trannie and weighs almost 10 kg more so yep if gobs of power is required i think the Krell will outpower the Vitus. Wish you were a bit closer so i could have a listen to it!
  12. Item: 8 RPG skyline diffusers Location: Innerish east Melbourne Price: $250 Item Condition: from good to poor see below Reason for selling: NLR Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: These used to sell for $350/pair. Been playing with these to figure out my next room treatment move. These are from an ex studio and some panels are damaged. 4 are ok 2 have corners missing and the other 2 have surface or further damage. see pics. Functionally are fine. Probably not suited to a shared family space as they are not pristine. Pickup only Photos: Advertisements without photos of the actual item will not be approved.
