| Amp Specs esp. DampFactor : Citation, Adcom, etc. Some folks are passionately against using specs in judging equipment and others, albeit a smaller group IMO, are just a passionate that specs/performance should be measurable. Personally, I'm a military historian and tend to be analytical, so whil... | |
| pro's and con's of a 4 ohm speaker? 8 ohm speaker will also double your damping factorAlthough that will not be true in the case of a tube amp, assuming the 8 ohm speaker would be connected to the 8 ohm tap, and the 4 ohm speaker would be connected to the 4 ohm tap. In those cases d... | |
| Is it ok to Bi-amp using different Brand/model of Would you please elaborate further on your 3rd paragraph (“complicates things a bit further, because the crossover will introduce some loss at mid/hi frequencies but not at low frequencies”), didn’t get what you mean. Thanks.Hi Norm,I'm envisionin... | |
| Fun Little Project for improving Dynamics Regardless of what one's attitude may be toward seemingly off-the-wall tweaks, I nominate Onhwy61's post as a candidate for "Best Post of the Week."BTW, for those who may not be aware, Hedy Lamarr really did make significant contributions to the d... | |
| Is it ok to Bi-amp using different Brand/model of My concern is different input sensitivity of the amps. The VK-60 is 1.0V. The SS BAT amps are rated at 1.5V. Does this mean when adjusting the volume on the pre-amp the gain on the two amps change at different rates. That is, do I need to re-adjus... | |
| White noise when XLR connection is used ... Just a guess, but I believe that the outputs of the Capitole are driven by 6021W tubes, and I would suspect that the tube or tubes that drive one or both of the two signals on the xlr connector is noisy and should be replaced.Concerning replacing ... | |
| What's First, Interconnects or Speaker? Longer lengths are specified for spdif (coax) cables. Does the same hold forth for optical (toslink) cables?No. The principles which make a 1.5+ meter length optimal for spdif coax cables are not applicable to optical cables.Which is not to say th... | |
| What's First, Interconnects or Speaker? While there is obviously no universally applicable answer, and while obviously technical factors cannot provide a complete answer, I suggest that you take the following into consideration:1)For line-level analog interconnects, the higher the outpu... | |
| shindo aurieges output impedance and other preamps I have no knowledge of how true it may be, but according to this post, "Actually the Shindo pre-amps all have a very low output impedance. The numbers often seen in their specs is the lowest possible input impedance of the partnering amplifier." Y... | |
| 100v mono blocks in series on 200v w/o transformer Don't do it!The resistance "looking into" the ac input of each amp will be inversely proportional to the amount of current drawn. If the amps are not pure Class A, that current will fluctuate widely with the music. At times when there is a high vo... | |
| Amp output is wired in series vs parallel? Hi Mitch,In the paralleled configuration, power capability into 8 ohms will be MUCH less than in the bridged configuration. It will probably increase significantly into 2 ohms, and not change dramatically into 4 ohms. And based on JA's comments ab... | |
| Who needs a MM cartridge type when we have MC? Hi Ed,As I indicated in my previous post, above a certain frequency a low pass rolloff will occur. However in the case of a MM cartridge if there is too little capacitance that rolloff will occur at a lower frequency than if optimal load capacitan... | |
| Great MONO recordings Try pretty much any symphonic recording conducted by Arturo Toscanini. The performances are so captivating you won't pay any attention to the primitive sonics.I particularly like his 1940 recording of the Brahms 1st. I have it on a set of Victor 7... | |
| Nakamichi deck directly into power amplifier Inna, it's possible to calculate the sensitivity from the power ratings for the 102 (100W into 8 ohms, 200W into 4 ohms) and the gain spec (27db). I just did a quick calculation, which indicates a sensitivity of slightly over 1.1 volts. Not an ide... | |
| Nakamichi deck directly into power amplifier According to the specs shown near the bottom of this page, the 682ZX has a 1 volt maximum output voltage, and an output impedance of 2.2K.So you would want to choose a power amp having an input sensitivity (the amount of input voltage required to ... |
