| An electrical engineer on how power cables can impact sound quality Although there is some RF coming in through the power line, most of the RF noise injected into our systems come from the nasty garbage we have in the room with our equipment. Namely, all digital equipment, laptops, desktops, microwaves in the ne... | |
| AudioQuest PowerQuest 2 or alternative? That market is so competitive that I doubt there is a deal to be had at any reasonable price point. AudioQuest has built a reputation so I am sure they won't want to tarnish their name. I think you are pretty safe with that approach. BTW, don... | |
| Reasons not to freak out about tube supplies Nice! Thanks for posting! This applies to a lot of things, especially selling off real estate in CA right after an earthquake! Man, you can buy acreage for 5 cents on the dollar. | |
| Mogami - Quad 12 ga. in the house! Thanks for the tip! | |
| MC901 monoblock tube matching Q Answer A: Call the manufacturer and ask. Answer B: If you can find a schematic, look at the tubes in a series stack or parallel stack and match those. In general, you want the gain tubes to be as low noise as possible, so spend a few extra d... | |
| Any Experience with BCS Gadgets? Yeah, the Mark Levinson ML3 for $1000 is way too good to be true. Seriously, a 200W Mark Levinson stereo power for $1000? I'd buy four at that price! | |
| Any Experience with BCS Gadgets? Do you have a link? I googled the name but didn't come up with a website. | |
| Cabinet resonance problem with Marantz MM9340 amplifier There are a lot of options out there. iFi makes one, although a bit tiny. I bought this one from these guys - https://www.atlhifi.com/product-category/fully-assembled-devices/ If you do buy from them, I suggest you don't use US Mail, as it tak... | |
| Cabinet resonance problem with Marantz MM9340 amplifier @mrdecibel That hum is caused by a DC offset in the power line. It happens and only a volt or three will cause it. There are several devices made to eliminate this, as the problem is worse with toroidal transformers. If you Google "Blocking M... | |
| Cabinet resonance problem with Marantz MM9340 amplifier I believe I discovered about 90% of the problem. There is a 1KVA, medical grade, toroidal isolation transformer that isolates my system from the grid. Thus any line leakage to neutrals or grounds is blocked, eliminating any hum induced from le... | |
| Power Conditioning on the Cheap If you monitor the voltage coming in from your distribution panel, you can determine if you have line sags or over voltage. The range allowed for your line voltage is quite large, so any changes will readily show up on a voltmeter. What you ca... | |
| Decisive moments your your audio journey First time was hearing Dave Brubeck Take Five on a 45 RPM on my cousin's mono 45 record machine, around 1958. Second time was hearing big band and other good music on a real stereo. I think that was around 1962. The next time was hearing Dahlq... | |
| diagram of a B & O 1513 turntable pin outs at the female connector where cart goes in Thee should be something on the B&O website. Did you check there? | |
| Sony HAP-Z!ES won't play after disk swap I can't answer your questions but the terrible service from Sony is disgusting. I have had similar problems from Sony Tech Support in the distant past so I try to avoid their stuff nowadays. Too bad, because they do make some good stuff. | |
| High pitched whine - unless Source Direct First thing is call Marantz and see what they say. Not to make a pun, but this sounds like an oscillation problem of some kind. How long are the interconnects from the Marantz to the Cyrus amps? When you tried to reconfigure the earthing, d... |
