| resistors in series/parallel questions... The above advice is good. However, it is very unusual to have a phono preamp with an input impedance of 100K. I suppose this is correct since you have spoken to the designer. Since you have access to the designer of the preamp, why don't you talk ... | |
| Amp and preamp impedance I agree with the previous advice. The response of a filter is dependent on the impedance of the source and the load. I admire your DIY spirit but I think you need to do a little more research into the problem. There are many fine electronics textb... | |
| What output is higher...? Sorry, can't help you there. I have a Wilson Benesch set up that came as a matched set and I'm afraid I am not that knowledgable about matching arms to cartridges.If you can get seven years out of a cartridge I think you are doing pretty well | |
| What output is higher...? A cartridge output could decrease for several reasons. Among these:As the cartridge ages, the material used to suspended the cantilever could lose elasticity and limit the motion. This would cause a decreased output since output voltage is proport... | |
| Shelving question I assume you have an older home with thick plaster walls over lathe. This means your walls are very thick, which renders your studfinder useless. In that case, drill holes and use molly bolts. This will hold a lot of weight. Another technique (sim... | |
| I'm Getting Unbalanced About Balanced Hi Mejames, there is really no such thing as a "truly balanced" output from a digital player. There is only one signal per channel stored on the disc, so every player that has a balanced output has to create the inverted signal to achieve a balanc... | |
| XLR vs RCA Hi Subaruguru, I said they were combined at the speaker. Not that they were unabalanced. The electrical signal that is applied to the speaker terminals is balanced but the motion of the speaker is not.Each driver can only move in one direction at ... | |
| I need to get suggestions on a high gain phono pre I suggest you check out the Aesthetix IO. Tube from front to back and can be as high in gain as you would ever need with great sonics and very low noise. You didn't mention a budget but a used basic IO can be had for around $2500, a good bargain i... | |
| Any others like L. Kottke Clone CD? Try John Fahey. I haven't heard this particular Leo Kottke so I can't comment on the recording quality, but Fahey is the guy who started it all. Try to find some of his early recordings on the Takoma label to sample his genius. Kottke ain't bad bu... | |
| XLR vs RCA I am with Warrenh. Even though Audioengr's points are valid, the last one is the biggest concern with balanced systems, the impossibility of designing a truly balanced system.A system that is balanced from beginning to end is actually two chains o... | |
| Low output MC - Math Question ?? voltage gain = inverse log (dB gain / 20)inverse log X is 10 raised to the power of XYou are looking to make up the difference of 15dB from the 80dB MC stage to the 65dB MM stage.15dB divided by 20 = .75take the inverse log of .75 = 5.6.3 mV times... | |
| Helpful Hint When Cleaning Records Oh, mine has a cork mat. I thought they all did. | |
| Helpful Hint When Cleaning Records Why don't you clean the mat on the machine just like you would clean a record? | |
| Clearaudio MAGIX Magnetic Isolators ? I agree with TWL. Another point is the claim that these devices "truely stop all resonence sound from your equipment, which actually is suspended on air."Yes, they are suspended in air with no mechanical connection to the platform. But they are no... | |
| Starting Over There are a variety of 2A3 and 300B integrated amps that can be had for around $1000, a set of Lowther medallionsfor around $2500 with nice drivers and a Toshiba sd9200 (DVD-A, CD, HDCD)for less than $800. Add a sub and you have a nice system for ... |
