| Cryogenic treatment of tubes? Anyone with experience positive or negative? I have never heard any difference, when comparing from the same batch lot.But I seen/heard from a few customers now their tubes got noisy or flared and died after cryo’ing. If you guys think about it Cro’ing your precious tubes is great way to mak... | |
| Primaluna dialogue premium HP tube rolling suggestions to reduce brightness leotis107 posts05-20-2017 1:28pmHey George, Thanks for showing those curves and explaining it.Had been wondering what it was about ultra linear that seemed so unpleasant. Yeah for a tube amp, their not very stable in ultralinear mode as JA of Ste... | |
| New Bel Canto REF600M using NCORE We spent a afternoon with them on different speakers. Make sure you hear them with your speakers before purchasing.As they "can" sound good with flat 4ohm’ish impedance, but also not so good if the upper-mid/high impedance curve of the speaker loo... | |
| DSD vs. PCM vs. MQA - Group listening experiment phillyb169 posts05-20-2017 6:12amRemastered anything will sound better than a poorly mastered CD or vinyl. Sorry Phill, this is 180’ out, but also half right with the "poorly" statement. The original first issue non remastered cd's and lp’s are ... | |
| Class D is just Dandy! randy-11982 posts05-19-2017 9:50amI also saw news on a new Class D amp from Constellation with very high switching freq. - dunno if it uses GaN devices... Just checked, just the same as everyone else 600-800khz if they used the new GaN semiconduc... | |

| Class D is just Dandy! I can only hope that the you can contribute as much for others in your life. Yeah you do, but you kinda attacked him personally.Cheers George | |
| Primaluna dialogue premium HP tube rolling suggestions to reduce brightness meiatflask Hi, to answer that properly without guesswork, I tried to find an impedance graph of your "proac tablette anniversary" speakers, but with no luck. While they are factory rated at 8ohms there could be dip/s maybe to 4ohms maybe in the p... | |
| Synergistic Red Fuse ... geoffkait Al and George must believe directional Arrows Al and George, the evidence is piling up. Al and George are the poster children for the Backfire Effect Slow down Geoff, or you'll blow your pooffoo valve, it just time to do a l... | |
| Class D is just Dandy! It's an open forum Erik, he's just at 180' to your "Dandy" propaganda. I'm sure in time he will give he reason/experiences for his comment, as he had 4k posts. Cheers George | |
| Primaluna dialogue premium HP tube rolling suggestions to reduce brightness I don’t believe output tube rolling is the answer to the OP’s problem, as the below will still be there and explain. One must remember speaker and the speaker wire introduce not only a resistive load to the amp but a capacitive one as well. ESL’s ... | |
| Synergistic Red Fuse ... IMO those numbers are so miniscule as to be:(a)Laughable. Geoff continues to assert that the HiFi Tuning measurements support the notion that fuses are inherently directional. This is also laughable Thank you Al. But I’ll go with what Geoff hear... | |
| Synergistic Red Fuse ... These DCR results show nothing! and can never be heard even by you with your bat ears, they have differences in hundredth’s!!! of milliohms!!!!!!!! (.00001 of an ohm) which mean nothing, this can be the change by the hand warming the probes or the... | |
