Purifi Class D: Junk? Datasheet: The output drives a 100Ω load Sorry, just looked at my notes, the MSB’s output buffer could be the LT1819https://www.analog.com/media/en/technical-documentation/data-sheets/18189fb.pdfCheers George | |
Rogue DragoN or Bel Canto Ref600 M This is not going to help much.Both use the Hypex NC500 modules but the Rogue has linear power supply and tube input buffer.Where the BelCanto use switch mode (smp) power supplies and an opamp input buffer.I like the idea of having a linear power ... | |
Purifi Class D: Junk? Data sheet: Each output drives a 150Ω load to ±7.5V with ±15V supplies The amplifiers are stable with any capacitive load making them useful in buffer or cable driving applications. No they are the output buffers in the rear of the MSB discret... | |
Purifi Class D: Junk? although you wouldn't be able to drive it to full power I can't speak to the Hypex but based on the idea that its input is about 2K (and thus similar to our module in that regard) I would not be surprised that George did this. No need to, I'... | |
Purifi Class D: Junk? You really are delusional, over and out sunshine. | |
Purifi Class D: Junk? Really, no wonder you left other forums, your > https://youtu.be/YTY26k0CA0I?t=5 | |
Purifi Class D: Junk? Like I said, you have no idea, even with proof from Scott. Also no idea either on streamers, all are still waiting for you to prove yourself right to everyone. We’re still waiting for your proof with links and CD cat. no. to prove you know what yo... | |
Purifi Class D: Junk? No, it is not, especially with the Hypex amps. The input is meant to be driven by a very low impedance source. Once again, you have no idea! The input impedance of the NC500 Hypex is 2k across the band, and can be driven by any buffer from a sourc... | |
Sound Quality of red book CDs vs.streaming Dealers are not making the profit margin on the few new "good cd only transports", that they can make on the multitude of streamers out there. Whenever a streamer (doesn’t matter what) comes to my place for an a/b shootout, it can’t match the CD t... | |
Why do you need so much power? Robert Harley answered your question years ago:"If the first watt isn't any good, why would you want 200 more of them?" Yeah well, that's also a load of ****The first couple of watts in any a/b amp are usually the better sounding Class-A biased... | |
Purifi Class D: Junk? In my past experience with the Nord Hypex NC500 monoblocks using the Sparkos and Sonic Imagery opamps, the differences were pretty obvious.Best is no buffer at all, direct in, as I’ve done. (you don’t need a buffer driving another buffer)If the ou... | |
Why do you need so much power? (I don’t crank it). Someone also suggested an Emotiva amp with 500W RMS. I'd like to know who the fool was that said that.Cheers George | |
What's in your CDP tonight? the minority report Tonight was Etta James "At Last" she made me cry on many of the the tracks.Best dynamic range version 2010http://dr.loudness-war.info/album/view/103607And the rest, worst as usual was 2016 streaming compressed to the max.http://dr.loudness-war.inf... | |
Cary 306/200 service? The ’pure silicone’ spray I got is petroleum based with hexanes and ketones - should evaporate It’s these things that make plastic dry out and become powdery and brittle and gears and things break when that happens, especially on old units like th... | |
Cary 306/200 service? Clean it, (Q-tips and alcohol) and try a little light lube, first.. Clean all tray sliders and plastic gears that move it with Q-tips and metho.But DON"T use any petroleum based lube on them, as this will cause them to deteriorate. I found the sma... |
