| comparation between Magnepan & KEF ref. series Gmood1...One must be careful about subjective evaluations of loudness. It has been shown that music sounds "Loud" when distortion occurs. Clean audio sounds less loud than distorted audio even if a meter will prove the oposite. This has been cited... | |
| Cobalt cable theory on bi-wiring. Fact or fiction? Zaikesman...True that Impedance (not just resistance) matters. However, low resistance is a big step in the right direction, and much easier and cheaper to do than Inductance minimization.I still think that the best approach is to minimize everyth... | |
| comparation between Magnepan & KEF ref. series Gmood1...You are accurate in the observation that power levels are never even close to the ratings of the amps that people use. But, my experience is always that higher power amps sound better. This was most clearly illustrated when I changed betw... | |
| Is there a SS amp that can offer tube bliss? Some tube-o-philes have suggested that digital amps resemble the "tube sound". In particular the CarverPro ZR1600 (which I use) is priced so low ($840 for 600 wpc at 4 ohms) that you might take a flyer and give it a try. | |
| Cobalt cable theory on bi-wiring. Fact or fiction? There is some theoretical effect (could be improvement or degradation) due to bi-wiring. It relates to the small signal that exists at the common (-) terminal of the speaker as a result of the impedance of the speaker wire. If you don't bi-wire, t... | |
| comparation between Magnepan & KEF ref. series I have a set of three MG1.6. The big question relates to Planar vs Cones. That is something you must decide for yourself. You must also come to terms with the visual impact. If the Planar spatial characteristics are to your liking, Maggies are an ... | |
| cartridge loading ? If the phono pickup is open circuit, (disconnected from the preamp, or with a very, very high input resistor) it will produce voltage. Since the circuit is open no current will flow. Motion of the stylus is resisted only by its mechanical complian... | |
| Fastest high-current SS amp below $1000 used? Probably some digital amp. Their output transistors (high speed switching fets) go full on to full off at about 500KHz. I really like the sound of my CarverPro ZR1600, but I would not give slew rate all the credit. | |
| Frequency Response of L.P's A vinyl disc can produce higher frequencies than a CD. The CD limit is 22 KHz, and it is a "brick wall"...nothing at all above it. However, fidelity does not degrade until this limit is reached. The fidelity of vinyl degrades gradually, and what y... | |
| Tuner deviation meter ? Analog FM tuners had a meter to help you get tuned accurately to the station's carrier frequency (Which is modulated to reflect the audio signal). Proper tuning minimizes distortion and noise. The meter should be adjusted for null: ie: centered.Di... | |
| digital optical interlink vs. coaxial Cytocycle...Please explain what you mean by "bandwidth" of an optical data transmission media. The light source is monochromatic, so any deficiency of "bandwidth" would just amount to lower transmissibility. The optical light source circuitry and ... | |
| Frequency Response of L.P's Zaikesman...As you say, response to several octive above the highest frequency of interest is an indication of good performance up to that frequency. When I was in college (many moons ago) I was a subject in some research project relating to heari... | |
| Frequency Response of L.P's Amps...no problem. Many speakers roll off by a few dB at 20KHz. Some supertweeters are good to 30Kc and higher. "Ultrasonic" transducers go much higher, but noone (except bats) cares about sonic fidelity at these frequencies. | |
| SA-XR25 or SA-XR45 ? I have the SA-XR25 model for my "souped up" TV (I really can't call it HT). However I do have the whole 5.1 setup, and agree with others that this is one fine piece of equipment. Features that the 45 has which the 25 does not are:1. On screen disp... | |
| rebiasing from 4 to 8 ohms? The purpose of the transformer is to make all speaker loads look the same to the tubes. The tubes don't know what the final load is, so bias should not be speaker load sensitive. |
