| Audioquest vs Hunt EDA Mk6 record brushes The Hunt and similar brushes work well as long as they are clean. After a few uses they load up on dust and crud and leave your records not much cleaner than they were before you brushed them. My solution? Use one of those "sticky rollers" to clea... | |
| I need help diagnosing a sibilant problem on vinyl David256, the " high frequency spike" when a MM cart. "plays through a defect" is not inherent to the cartridge. It's the result of improper loading. Typical MM carts have a rather high inductance compared to the usual MCs. This makes them much mo... | |
| I need help diagnosing a sibilant problem on vinyl You can add inadequate PS filtration in the Phono Pre and the rest of the chain to the list. I have become aware of this over the last year or so. My DIY gear (all K%K Audio fully differential designs) use active constant current sources in series... | |
| Silver MC step-up Oops! That should be 0.3V rms, not .3mV. Sorry. | |
| Silver MC step-up I have made the switch from copper LL1931s to the silver LL1931s in my K&K Audio beta Venice phono pre. To my ears a more natural, open and detailed sound. A well written discussion of the differences is posted the K&K Audio AudioAsylum si... | |
| Oh no , not another phono stage rec K&K Audio Standard MaxedOut MM - $1349 kit, $1649 assembled. With the latest improvement which involved replacing the input JFETs with MOSFETs the sound has been much improved: increased delineation of space, more transparency, more natural ti... | |
| Burn in Step up transformer with ipod. I can't believe the amount misinformation and bad advice that is being spread on the web by these forums. Against my better judgement let's address some of the issues raised on this tread:1 - an AC signal of .2-.3Vrms will not saturate the core of... | |
| Burn in Step up transformer with ipod. I just fed the input with the phono pre turned off. You will probably want to use a high value of resistance as a load so as not to load down whatever device you are using to provide the signal too much. Remember, if the load resistor is on the se... | |
| Burn in Step up transformer with ipod. Kevin Carter of K&K Audio, the US distributor for Lundahl transformers burns in new MC transformers with line level signals. As long as transformer is properly loaded and phono stage is off or not connected I see no problem. In fact, burn in i... | |
| How far out to place motor from platter Manitunc, assuming stretching the belt does not change the angular velocity of the motor it will not change the platter "speed" as this depends on the motor's rotation and the ratio of the platters diameter to the pulley's diameter. Changing the l... | |
| Best MC step up transformer Dear Syntax, no voodoo here. Kevin doesn't believe in it. By changing an active device to one with a different transfer function you can effect a real change. Not the usual audiofool crap. In this case existing JFETs are swapped for MOSFETs at the... | |
| Best MC step up transformer Wrm57The Sonus Veritas Venice is available now. Contact Kevin or Joe, I'm sure either one would be more than happy to set you up with one. And here's a heads up for all K&K phono pre owners: Kevin has a new upgrade in the works that is absolut... | |
| hissing sibilants In my experience you can have cart. alignment (VTA etc.) and loading correct and still have problems due to issues with the electronics that you are using. You are dealing with a thorny problem for which there are no silver bullets. It will take s... | |
| Best MC step up transformer I'm using a pair of silver Lundahl 1931AGs fronting a Sonus Veritas beta Venice. Transparency is not an issue. Neither are dynamics (micro and macro), transient response, harmonic development or musical flow. Bad news, not cheap. | |
| RCA to balanced Nsgarth, the discussion here was line out transformers, not MC input transformers. Although even here good SUTs are very competitive. For example the new Lundahl silver LL1931AG at $800/unit. That's performance competitive, maybe not price competi... |
