| Passive preamp issues or? As I asked you to put in your Blue Note 2 in, did you? (which also has volume) Direct into the poweramp, and then you can see if the problems disappears.If it does then the Jolida tube output is the problem, and even if it doesn’t make noise will ... | |
| Passive preamp issues or? I’d say without ever doing the experiment to see on the test bench or hear also, this 47kohm output impedance "could" be the problem. As it will also be "capacitor coupled" as well being tube which "could" make it even more of a problem if the cap... | |
| Passive preamp issues or? If it is 47kohm output impedance, that’s insanely high, never seen anything like it.If you get no answer, also try another source with output rca’s like the Blue Note 2 streamer as it has volume control also, see if it still hums then.Cheers George | |
| Passive preamp issues or? I’m not saying a grounding issue, that’s why I asked for you to find out what the output impedance is of the dac (at all volume levels) as this sound like it’s the dac impedance match maybe problem, or it's hum in the dac just being presented.Chee... | |

| Passive preamp issues or? Sorry I should of elaborated a little better when I said the tube doesn’t decide the gain, in that it (the tube) doesn’t decide the gain in a tube output "buffer circuit" as you most probably have in this dac.Cheers George | |
| Passive preamp issues or? The gain will be the same, the tube doesn't decide it, the components around it do. Do you know at what stage the volume control is done on the dac? Cheers George | |
| Pass Labs int 60 vs. Luxman 590 uX ii That would be a killer amp for my near-field listening set-up, George. Got the perfect amp for your nearfield listening, look at a pair of only 25w into 8ohm monoblocks, like the Mark Levison ML2 monos of yesteryear they do an even better doubl... | |
| Pass Labs int 60 vs. Luxman 590 uX ii not really sure why you’d be throwing the ’fanboy’ slur around. I was a big fan of Nelson with Threshold (bi-polar), but not so much with complimentary push pull Mosfets Pass Labs, as the P channel Mosfet always let them down big time for curren... | |
| Passive preamp issues or? renisnceman The change in detail and depth was not subtle. Soundstage extended beyond the speakers- everything just sounded better. However, with the high gain of the Nuforce there’s a hum in the speakers The Nuforce STA200 has an input sensitivit... | |
| Filter capacitance-how does it relate to amplifier performance? By the way, the tube amps absolutely kill the Threshold in bass response...much better control of the big 12" woofers in the NorthCreek crossovered Matrix 801 S2s Understandable when you look at the very "benign impedance load" of the 801’s https... | |
| Pass Labs int 60 vs. Luxman 590 uX ii dwest1023 I actually own and use the pass int 60. It is a smooth and warm in the middle amp. At the same time is is very transparent. It tends to get out of the way of the music and you just listen. Bass is very controlled and doubles its power in... | |
| Filter capacitance-how does it relate to amplifier performance? My understanding of capacitors is that they store energy. Does this mean that my Due amplifier is just as powerful as the on paper more powerful Atoll in300?For comparison sake with my Due amplifier I demoed a Plinius Hautonga integrated amp with ... | |
| Pass Labs int 60 vs. Luxman 590 uX ii For some one who loves Pass, you just did Pass a huge disservice. Really!!No, you just been caught out not knowing what constitutes low output impedance (good damping factor) in an amp and were pulled up on it, that why your backs ups, everyone k... | |
| Pass Labs int 60 vs. Luxman 590 uX ii builder3 Can you elaborate on your statement regarding the mid-bass, Erik. Here’s the piece I find important.Per Luxman’s website, the 590 has: Bipolar 3-parallel push-pullBut the 509 has:Bipolar 4-parallel push-pullImplying a lower output impeda... |
