| Speakers causing problems with TV If the problem remains even if you remove the speakers the TV has been magnetized, so it has a constant field. Consider degaussing your TV. | |
| Whats the best way to clean speaker grills? Vacuum cleaning with the "curtains" hose should do the trick. | |
| What type of digital cable is best? XLR or optical Back in my university years I did a lab experiment on the quality of optical fibers. I can assure you that the plastic fiber used in toslink is far inferior that the coaxial copper cable, suffering significan signal losses. Glass optical fiber (kn... | |
| Tube Quality / Russian 6550 There are many factories that assemble tubes in Russia. Could it be that Sovtek buys from them and just adds the brand? On the other hand Svetlana has some unusual designs so it may have a factory of its own. Of course tubes do come in some variet... | |
| Replacement Drivers Unfortunately the cone diameter is only one of the factors that should be taken into account. Other, like magnet strength, suspesion stiffness, maximum excursion, coil diameter should be also checked. So, buy exactly the same drivers as the ones y... | |
| Copying LPs to CDs You must have a high quality sound card with A/D converters. Then you will be able to store your LPs as .wav files on the hard disk and then burn the CD-R. The software is usually provided with the card, or you can get shareware. But the quality o... | |
| tubes for phono section Best replacements for 6DJ8: Sovtek 6922, Tesla ECC88 and Amperex 7803 However, Sovtek is supposed to have the less noise, so it is probably better suited to a phono stage. | |
| 'planar' vs. 'boxes' The electrostatics offerer unsurpassed midrange. But the sheer size of the planar drivers to creat bass, the need for powerful amplifiers and the high cost stack against the planars. Unfortunately hybrids (that use cone drivers for the low frequen... | |
| Bi Wiring - Any Good Crossovers can be "parallel" or "serial". In the former the bass and treble signals are split before processing; in the latter the signal passes through some components before it is split. Almost all crossovers are "parallel" because they are far ... | |
| custom-built tube amps Advances in tube circuit design in the last 30 years are almost non-existent; after all the SE triodes date from the '30s. So every competent technician can copy an old design, use high quality modern parts and come out with a decent tube amp. Man... | |
| Leaving Amps on I saw no harm when I left my amps on, but the brown-out is always a fear and may damage your speakers too. If you are using tubes, or class-A transistors the heat and the component wear is also something to consider. As a rule, I leave digital com... | |
| Copy CD My friends and I did a rather exausting comparison last year. OK, on a very revealing ($20000) system, disks copied from a hi-end Meridian transport to a ridiculously expensive professional Marantz CD-R were slightly better than the originals. Thi... | |
| Rogers LS3/5a is 'the reference' speaker They still have excellent qualities, even after all these year, but to my ears "monitor" today means ATC. | |
| Best Cartridge cost no object Guys, cost-no-object is an oxymoron in cartridges. Remember you actually rent those thingys: the price of retipping and actual replacement once the suspension runs out is dear. I'd go for a reliable good sounding than a fragile excellent sounding ... | |
| Blowen Amp, Looking for replacement, any thoughts Don't write off the Sumo yet. A friend faced similar problems with an old Electrocompaniet. The output transistors which were bolted with two screws each on the heatsinks were no longer available. But a crafty repairman found the corresponding new... |
