| Does anyone care to ask an amplifier designer a technical question? My door is open. Regarding the issue of cartridge loading, in a past thread here Jonathan Carr (Lyra cartridge designer, who I believe has also designed some phono stages) stated as follows: I should now debunk another myth regarding loading, which is that low-imp... | |
| Best tools to calibrate TT motor actual speed? Hi Uberwaltz,I too use the KAB Speed Strobe. It can be purchased from various online sellers, but as you may have already discovered it costs $110. (Mine was "only" $90 when I purchased it about 10 years ago).An alternative approach costing almo... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. I recall that in a thread here a while back Kevin Deal of Upscale Audio also mentioned very emphatically that 6SN7s are often microphonic.FWIW, though, during the approximately seven years in which I owned a VAC Renaissance 70/70 MkIII, which uses... | |
| Are Pass Labs amps probably the best ever you can buy ? Yes, that sounds very fair indeed, Wolfie. And it will cover most of the cost of my XA25.I’ll let you know when the check arrives.Best regards-- Al 😊 | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @prof, I'm sure Roger would take this into account, but keep in mind that since the CJ Premier 12 and the Eico HF81 are both tube amps and have output transformers, they should not be operated unloaded while they are being provided with a signal.... | |
| Where do cables upgrades have the most impact? Mishan 12-3-2018 Using the example of intercon cables (the same manufacturer and the same model), I can say that in most cases a cable 1 or 0.8 meters long sounded better than half a meter long. I suspect that the matter is in some "wave" nuances,... | |
| Where do cables upgrades have the most impact? Factors that tend to increase the criticality of speaker cables:-- Low speaker impedance.-- Long cable length.Factors that tend to increase the criticality of line-level analog interconnect cables:-- High output impedance of the component driving... | |
| Are Pass Labs amps probably the best ever you can buy ? Regarding the SIT3, an important point to note is that it has an extremely low gain (for a power amp) of only 11.5 db. Power amp gains are typically in the mid to high 20s. Most Pass Labs amps have gains of 26 db for example, although most of th... | |
| could somebody help me out on the benefits of expensive phono and speaker cables? Looking at your specific equipment I suspect that what is likely to make the greatest sonic difference when it comes to cabling would be to have a technician rewire your turntable with a phono cable having very low capacitance. And re-doing the in... | |
| Preferred Contact Cleaner and Contact Enhancer for Audio? Like some of the others I use DeoxIT Gold liquid.Regards,-- Al | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Hi Ian (Ieales),Surely you realize that pi squared, rounded off slightly, equals:3.14 x 3.14 = 9.86Best regards,-- Al | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Ralph (Atmasphere), thanks for your characteristically very constructive and informative post above. A very minor correction, though, for the record. I’m sure you misspoke when you referred to pi-squared. The 6.28 factor you referred to is of cour... | |
| If you could only keep 5 record albums, what would they be? You'll probably find the following thread to be of interest, which asked essentially the same question:https://forum.audiogon.com/discussions/you-can-only-take-5-albums-to-a-deserted-islandMy answer in that thread:Brahms, Symphony No. 1Chopin, Pia... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Ramtubes 11-27-2018: Thanks for your measurements and math. I think the math will leave most with their head swimming. Perhaps you could add some details to the steps so that others, less math inclined, might work things out. it is nice for people... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Ramtubes 11-26-2018: HI, Roger here with a question.I would like to hear how each of you figured out how much power you needed to buy in watts?I would appreciate the following information in your response. Your listening level LOUD SPL (preferably... |
