| What amps do Electrical Engineers own...why? Gfcf, EE's are a diverse lot, just like the general population. As can be seen in many of the responses that have been posted in this thread, the answer to your question is clearly no.However, it would probably be fair to say that the EE's at A'go... | |
| ? for ya, Al Elizabeth and Abucktwoeighty, I appreciate the kind words. Thanks!Zd542, thanks for the response.If pin 3 is grounded from the factory, wouldn't that imply that the internal signal path in the preamp is unbalanced, as well?Yes, but the converse is... | |
| ? for ya, Al Zd542, thanks for pointing that out. But to clarify, do you mean that there is only one signal on the XLR connectors (the "hot" signal on pin 2), and pin 3 is grounded instead of being provided with the inverted or "cold" signal that would normall... | |
| Anyone hear of the Black Cable Tie tweak? No, John (Jmcgrogan2). Perhaps I was too subtle. My comment was a dig at those who seem to feel that it is never legitimate to reject a tweak "a priori," no matter how absurd the tweak may seem to be.Happy holidays! Best regards,-- Al | |
| Anyone hear of the Black Cable Tie tweak? It is common in debates about controversial tweaks for "believers" to say to "skeptics" something like "you can't say it doesn't work if you haven't tried it."Perhaps this particular tweak serves as an illustration that there are finite limits to ... | |
| Tube Pre-Amp Recommendation Ralph, note this statement in the OP's initial post:Amplifier: Audio GD Master 2 Series Mono Blocks (Will Upgrade Later to Krell, Macintosh or Pass)The Audio GD Master 2 is indicated as being a fully balanced design, with an XLR input impedance of... | |
| Converting tube preamp from 110v to 230v Not sure if a step-down transformer will degrade the sound with the particular preamp, but I would expect that there is less likelihood of degradation using a transformer with a preamp, that draws an essentially constant amount of current all the ... | |
| ? for ya, Al Hi B,It depends on the specific design, and especially on whether the RCA and XLR outputs are separately buffered (driven from separate output stages), as opposed to the RCA output signal being driven from the same circuit point as one of the two ... | |
| Nordost ICs mixing with other speaker cables See this recent thread, among other past threads, for a discussion of this issue. As you'll see, there is no consensus.In my post in that thread dated 12-15-12 I listed many ways in which the effects of interconnect cables, speaker cables, digital... | |
| Can a change in negative feedback sound better? Hi Nonoise,First, the Dakiom device is not changing the amount of negative feedback. It can't do that because it is not within the amplifier's feedback loop. (Although it would be within the feedback loop if the amp were one of a very small handfu... | |
| What amps do Electrical Engineers own...why? 12-22-12: Charles1dadNo NFB and DHT tubes is a very solid foundation to build with. Has it meet your expectations?Yes, I continue to be delighted with the amp, particularly since I upgraded the stock 6SN7's to Sophia Electrics. Some vintage Sylvan... | |
| What amps do Electrical Engineers own...why? Which ever amps have the BEST specs.Not in the case of this EE. IMO the proper (and necessary) role of specs is to allow one to identify and RULE OUT from consideration candidates that would be poor matches to either the surrounding components (fo... | |
| how much of a difference should equipment make? What other factors are in play regarding bass definition?In addition to the distortion-related issues I mentioned earlier, the quality of the power supply design certainly figures to be a significant factor. In part because a great deal of the ene... | |
| how much of a difference should equipment make? Michael (Swampwalker), thanks for noticing that. My first response indeed addressed the claim in Peter's preceding post that:When you go from a damping factor of up to 500 and compare that to an amp with 1000 or more, you're talking about audible ... | |
| how much of a difference should equipment make? Peter, consider the fact that many and probably most high quality tube amplifiers have damping factors that are less than 10. I don't think that anyone would deny that there are a lot of users out there with expensive, high quality, essentially fu... |
