| Setting cathode bias in my tube amps manually, how accurate must I be? Cathode biasing is usually automatic, you loose a little power with this, that's why many use fixed biasing which can be adjusted.https://idealinnovations.biz/biastubes.htm Cheers George | |
| basic passive preamp hocheye Sent you a PM re the Reference Line preeminance one, I can always have another passive to do demo A/B's against my unit.Cheers George | |
| Synergistic Red Fuse ... is there a fuse made that has a built in fire extinguisher? I don't think so, but there is one that comes with a 30 day free psychologist.Cheers George | |
| Speaker wattage question paraneerSpeaker wattage ratings are generally meaningless. The two key specs are impedance and sensitivity when matching an amp to a pair of speakers. Add to that a third, any high negative phase angles at low impedance's as well.Cheers Ge... | |
| advice- DACs with Tubes, Or??? budget If looking at the Jolida, be careful what you are driving with it, as it has a very high output impedance of 3kohm. They don't advertise this, but I got a customer of mine who owns one to email and ask them. Cheers George | |

| Is upgrading pre worth it? kingdombuildingcon Hi, your Rogue ST100 has an input impedance of 200kohms with an input sensitivity of just 1v in for full output.These ST100 specs makes it a great candidate for a passive volume control, which will be the most transparent/dynam... | |
| DACs that upsample to DSD internally? xrayz Why? I just want to try DSD. Maybe I won't like it at all, I don't know. That's the only reason, and probably the only reason all us on here try different equipment. That's fine, but listen to real dsd (native), not pcm that was conver... | |
| Test CD s, which ones to get. If you talking about proper technicians test cd's then you can't go passed.1: http://www.stereophile.com/content/recording-november-1988-ipierre-verany-digital-test-cdi#IQ1OYpDXIOxd1TJ4.972: http://www.allmusic.com/album/denon-audio-technical-cd-... | |
| DACs that upsample to DSD internally? xrayz As Allen said said in the second post, why??Your only denigrating PCM by converting it to dsd in real time with a dsd dac, better off getting the right dac to it with, get a good Multibit dac, which converts it "bit perfect".From MoJo Music... | |
| Difference between Schiit Modi Versions There's only two different dacs, the base Bitfrost which is Delta Sigma based Wolfson conversion. Or the more expensive the Bitfrost Multibit, which as the name implies is Multibit Analog Devices conversion.There is Bitfrost upgrade cards to old ... | |

| DSD vs. PCM vs. MQA - Group listening experiment Look at the title, "DSD vs. PCM vs. MQA" it can't be done fairly without compromises using the same dac.Maybe it's you that needs knowledge or professional help, as one of your statements suggests, "The ripped cd file sounds better than the cd spi... | |
| DSD vs. PCM vs. MQA - Group listening experiment jon when are you going to stop trying to be a forum cop?? The OP asks in his title " DSD vs. PCM vs. MQA Group listening experiment "I say it can be done with any validity because one dac can't do all at their best!!! So it can't be a valid co... | |
| DSD vs. PCM vs. MQA - Group listening experiment BTW here are a users findings of the Schiit dacs with Multibit upgrades doing pcm conversions.https://forum.audiogon.com/discussions/difference-between-schiit-modi-versions So saying that it's really impossible to compare DSD, and PCM as they both... |
