| You could work for any manufacturer, past or present... Without knowing any audio designers personally I tend to think that those who would be best to work for are (a) those having well established top-notch design talents, and (b) those whose companies are known for being conscientious, responsive, an... | |
| Pure Class A SS vs Tube Amp ... my new preamp Michi P5 is class A design @glennewdick makes an excellent point about usable volume control range. And that is a particularly important consideration in this case because the Rotel Michi P5 preamp has high gain. According to my... | |
| Pure Class A SS vs Tube Amp It appears that the KLF 30 is actually rated at 102 db/1 watt/1 meter, and given the horn loading of its mid-range and high frequency drivers I suspect that rating is reasonably accurate.A concern such high efficiency raises is that the noise perf... | |
| Seriously considering tube preamp…opinions? Do I just go by the 1/10 rule (output impedance for the pre)? No.To assure impedance compatibility the 10x rule of thumb guideline should be applied at the audible frequency for which the output impedance of the component providing the signal is ... | |
| Seriously considering tube preamp…opinions? Regarding the PrimaLuna EVO 400, I don’t know about that specific model but Stereophile’s measurements of several other PrimaLuna amps reveal them to have very high output impedances, even for tube amps. That stands a good chance of resulting in t... | |
| Seriously considering tube preamp…opinions? From a specification standpoint I don’t see any issues pairing the Quicksilver Line Stage and 60 watt mono amps with low efficiency speakers such as the Salk WOW1, provided that peak SPLs in the mid to upper 90s at the listening position are suffi... | |
| Equi=Core Hum & Other Issues @Millercarbon, as someone who has been here for not much more than a year you may not be aware that over the course of many years it has become abundantly clear to long-time participants that Jim (Jea48) knows more about electrician-related matter... | |
| Equi=Core Hum & Other Issues Hi Lowrider,DC offset on an AC power line can't be measured with an ordinary multimeter, or with the device you purchased. Although after looking at the description of the device I'm not sure why it indicated an overload. Apparently it automat... | |
| What is the voltage To bias a marantz 8b? Great find, @imhififan That looks like an excellent, easy to use, and safe to use solution.I believe it will provide results which are **slightly** less accurate than the original meter would have provided, because the cathode current that is meas... | |
| Seriously considering tube preamp…opinions? Caution: This is a long post :)Here are some comments concerning amplification that I would add to this excellent discussion, which also have potential implications regarding speaker selection:First, small box-type two-way speakers (such as those... | |
| If I have good local shops available, should I restrict my purchasing? +3 @tvad (or whatever the + count is at this point). Very well said.Tablejockey 2-22-2020 So, everyone here is being ethical, by claiming EVERY out of state purchase they didn’t pay sales tax on...RIGHT?I doubt it. I for one have always been scrup... | |
| What is the voltage To bias a marantz 8b? Clever suggestion, @noromance . I hadn't thought of that technique. Thanks!Best regards,-- Al | |

| Speaker sensitivity, impedance, and calculating amp power daledeee1 2-20-2020 How can an amp have different current output with the same "wattage" as a different brand? With a very few exceptions, nearly all solid state amps are designed such that for a given input voltage their output voltage remains es... | |
| Bits Are Bits, Right? Mkgus 2-21-2020If it’s all the same data and the read errors are minimal, then what is happening before the buffer is having effect on the sound.As I see it the reason is that what is happening before the buffer, which is dependent on the physical... |
