| Good CD player vs. Transport and DAC Transports wear out. DACs do not. This is true, and to many enough reason to go separates. But from what I’ve learn’t from some digital gurus.For the best "sound quality" transport to dac coupling, you can’t go better that a single box cdp.As the... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Technical question: Do certain electronic components, e.g. capacitors, need to "form" before they operate at their best? It takes electrolytic capacitors no time at all to form (certainly not days or weeks) with the correct polarizing voltage, an... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. I find no references to burn in in the 50s 60s 70s.. when did it start? I first heard of it, when the first burn in CD was produced to suck the gullible in so the makers could make some bucks, as they weren't cheap, I think it was Monster that ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Is the phase shift what they like? Could very well be Roger, that’s why I posted this as the possible explanation.Especially in this case with a 0.47uf Wima coupling cap on the output of the Mani phono which is then loaded with his 5kohm pot to g... | |
| The Future of Audio Amplification " Where are we at with class D right now? Everyone keeps saying that the future is class D but where is that in the future?" I do too, and it will come, when they've got it all right, with no compromises. When they get rid of it's "flaws".Every... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. almarg George, I was wondering the same thing, so I took a look at Krelldreams’ posts earlier in the thread and it appears he is presently using a Schiit Mani phono stage Think I found it.Output impedance of the Mani at 75ohms is fine, but i... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. krelldreams I primarily listen to LPs, but I do have a DAC (Cambridge DacMagic Plus) What would your phono stage be, hopefully I can find it’s output impedance and if it has capacitor coupling and if that’s big enough, to work into a 5kohm Alps ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Mr. Modjeski seems to endorse passives Yes his amps are loved by passives and with my customers that use them. My power amp is a CJ Evolution 2000 its input impedance is 100k ohms, and input sensitivity is 900 mV to full output.It should also lov... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. krelldreams my passive across the input to the output as you requested. It measures 1.21kohm, which is as written on the bottom of the case. If your Alps pot’s passive pre, input to output measures 1.21kohm then you have a 5kohm Alps pot. Your s... | |
| Tubes with Infinity IRS Betas You said it yourself "many moons ago"...let’s say customer A has a nice used pair of Beta’s, a fully refurbed Threshold S/500 Series II (of which you’re very familiar) and a 2nd hand ARC Reference 110 with new NOS tubes, where are you going to pu... | |
| Lowering House Grounding Impedance I use 2 x grounds together just in case, one is the cold water pipe and the other is a copper clad earth stake driven deep into the ground. as earth stakes are sometimes not so good if the ground is low in saline content. Cheers George | |
| Gryphon vs Swiss solid state amps and preamps. And integrateds. inna OP Yes sure, I would prefer used Antillion. Most used Gryphons that I see are in Europe or Asia, different voltage. Have a look at the double click magnified shot of the back of this one for sale, sure looks to me they are changeable, maybe... | |
| Tubes with Infinity IRS Betas rvito Tubes with Infinity IRS Betas When they were first shown in Australia many moons ago at the Amada Conference Room Artarmon, the importer Ceto from Audio Excellence gave the old propaganda speech before playing them.In that speech before we... | |
| First Watt and Aleph amps with Tortuga passive preamp In my case, that Aleph 2 amps (10K input impedance) were possibly incompatible but I took a chance and bought them anyway. Turns out that there is no problem with this match-up. The 10kohm input is not incompatible, but not perfect. It will wo... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I had mentioned in my review that the AHB2 is not able to drive the Kingsound King III electrostatic to an unlimited level of listening. However, there is no degradation of sound as the amp is pushed to its limit, and there is no degradation asso... |
