| What the benifit of using a separate dac? Obviously it depends on the quality of the DAC built into your player. There is no logical reason why a DAC housed in a separate chassis should be better. Take care before you spend money. D/A converters have been greatly improved in the last few ... | |
| Best of the 80's &90's Amps & Preamps Tandberg recievers were great.Kenwood LO7M power amp. DC-coupled for awesome bass. | |
| recapping crossovers....do or don't? Wavetrader...Comparing stock and modified speakers is very easy. You put them side by side, play a mono source, and swing the balance control from side to side. | |
| recapping crossovers....do or don't? Wavetrader...That's good news. Maybe it means that they knew what they were doing when they picked the capacitors. If you do make changes, do only one speaker to start with so that you can compare your results with the stock XO. | |
| recapping crossovers....do or don't? Capacitors are a can of worms. Unless they are truly junk change out the inductors first using air cores wherever the original XO used iron cores. | |
| How important is S/N Ratio....? There is no "standard" dB level for a jet plane. Some business jets are so quiet that we don't know they have arrived at our little local airport until they taxi up to the terminal. On the other hand, I have had occasion to work with an F15 fighte... | |
| Question about tubes in the old days Many tube amps did not have adjustable bias voltage. The tubes were "self biased". This means less power amd/or more distortion, but it did mean a lot less fussy work.Tubes seemed to last forever. I once had a Heathkit amp where the output tubes p... | |
| How important is S/N Ratio....? If you listen to loud-all-the-time rock music S/N is of no concern. For quiet classical music 90 dB is OK. 100 dB or more is for neurotic audiophiles who put their ear to the speaker when no music is playing. (By the way, most of my stuff is spec'... | |
| Anyone ever tried 2x100Watt Bi-Amp Vs 200 Watt Biamping was very effective back in the days when power amps had high IM distortion, and watts were expensive. The only valid reason to biamp today is to get rid of the passive crossover. | |
| Why Not Bring Back Analog, Reel to Reel Tape Mag tape is inherently expensive to duplicate. You have to draw the tape past a record head so that the music is recorded note-by-note. Perhaps speeded up a bit, but that hurts quality. A vinyl LP is stamped out so that all the music is copied at ... | |
| Is it ok for tube amp directly to the outlet? Tubes are not damaged by voltage spikes that would zap transistors. | |
| Why are older tubes so much sought after Newbee...I was around in those days. Our tube equipment hummed, hissed, and produced so much IM distortion that one percent harmonic distortion was not a problem! Our goal was to improve these measurements, and I guess we were successful except fo... | |
| cd plays without preamp You were drunk at the time. | |
| Why are older tubes so much sought after So I guess that the one thing that everyone agrees about is that tubes "color" (alter) the sound: opinions vary regarding the best color. But I thought the objective is to reproduce sound with "High Fidelity", which means without alteration. There... | |
| Spectrum analyzer? Kr4...You say "Corrections based on RTA, only, are chancy."Perhaps, but the $350 I bet on my first DEQ2496 has paid off better than any other expendature on my audio system. As the saying goes "Don't let the search for perfection prevent the very ... |
