| Streaming for beginner I think I am less knowledgeable than many beginners on streaming and downloads. Hoping I made a good choice I bought a Bluesound Vault 2i and ripped about 170 CDs, all of my CD collection. With customer service help I made three spare copies of wh... | |
| A Couple Little Things I'm Wondering About In the matter of electromagnetic radiation from a speaker cable, at 20,000 Hz at the speed of light or close thereto, how could different arrival times of a signal through the fraction of a second of two or three meters of cable at 300,000,000 met... | |
| Bluesound Vault 2i, Cocktail Audio X40 or ?????????? I purchased a Bluesound Vault 2i late last spring and at first it worked but was so complicated to operate that several times I needed telephone help from someone who I had take control of my computer and made a copy of the music library I had mad... | |
| Msb dacs why not alot of postings I purchased an MSB Platinum DAC early in the first decade of this century when I had the income to do it. Because I prefer single ended triode amplifiers using AM radio station transmitter tubes so I don't have to use highly sensitive speakers I b... | |
| Bluesound Vault 2 I purchased the Vault 2i and ripped all my CDs. I listen to classical music only and the program is impossible to index by composer. My library is about 30 GB and I have a backup of two days it took to rip my library to which I added some 24/96 do... | |
| Help me understand "the swarm" in the broader audiophile world Mine is not likely typical. I tried to integrate subwoofers with Magnepan 0.7's and the subwoofer or pair of them always call attention to themselves without integrating into Magnepans. I wanted a more full bodied bass and I now use a pair of DWM'... | |
| Tubes? If anybody has the balls to do it, an 833-A SET with its grid driven by a tube headphone amp with a transformer output about 600 Ohms and the 1000 Volt B+ to the 833A's through Hammond 1642SE transformer will give you more than enough power. It is... | |
| A pragmatic view of cartridge expenses / many questions I find something almost Zen about tangential tracking tone arms, playing back the record the way it was cut. But there are several reasons I would not do it. First is the need for near frictionless air bearings, the noise of an air pump and air hi... | |
| My pet peeve: "revealing" speakers I think what you describe about speakers also applies to live music in a concert hall or an opera house. The sound is colored by differences in acoustics in different seats, how many people are seated near you, and how absorptive the clothes they ... | |
| Replacing driver screws with brass screws It is not necessarily the brass vs ferromagnetic steel screws but screws better bonding speaker frames to the cabinet. | |
| Sam here.l realize now why so many people think my ideas are crazy? Laboratory measurements of the specific electromagnetic Maxwell equations 3 and 4 you adduce, please. | |
| Anybody want a laugh? I make my own amplifiers and get to choose to over-design: resistors rated for several times the wattage they will dissipate, Polypropylene power supply capacitors rated at more than twice the voltage (2.3 kV rating foe a 1 kV power supply) transf... | |
| A challenge to the "measurement" camp While I agree with listening experiments with cables, my quarrel is with the "physics" used to sell cable designs. The most common is skin effect, which is accused of causing high frequency roll-off and distorting phase angles of different frequen... | |
| Who says cables don't make a difference? While there could be a difference, there is some bad physics used to sell some cables. For instance, skin effect and the claim to need to mitigate it with litz or ribbon construction. Skin effect is alleged to increase the resistance of speaker ca... | |
| Best tube preamplifier for under $15k I like the 27 SET preamplifier, but it has to have DC for the cathode heaters to silence hum and it is very tricky for its plate power. I like the blue glass Arcturus 27's and they sound good too. You have to build your own. You can also use 2C22'... |
