| Does anyone care to ask an amplifier designer a technical question? My door is open. @mapman Lifelike SPL for me is that what one might hear at a similar live performance in the good seats, not too close but not too far away.I want my gear to be able to handle it all including perhaps sitting close to the percussion at the symph... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @donjr A friend of mine loves Accuphase. I have seen inside and its beautifully built, measures well but its just too many parts. Their preamp has something like 600 transistors and 1200 diodes. Im into simple circuits. Sure would love to see the ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @almarg It would help to quote the original question so we can follow this. It appears to be an answer but im not getting it. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @mapman Back in the 70s selling most popular receiver lines from Pioneer to sansui to Tandberg the more powerful models in a line (generally up to 120 w/ch or so) ALWAYS sounded better at least at moderate or higher levels. Clipping is always p... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @georgehifi https://www.stereophile.com/content/leben-cs300-integrated-amplifier-measurementsJA does make mention of the ultrasonic resonance, but "maybe" because they’re an advertiser, didn’t make too big a deal of it. Thanks for the link. When s... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @terry9 Thanks for all your help, Roger. You really have opened up a stack of stuff for me to do. Much, much appreciated.Hate to be pedantic, but I think that the 45uF figure should be 4.5uF, which is less of a problem: (75**2) * (800 * 10*... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ieales A balanced input is no guarantee of better sonics. The devil is in the details.Every audiophile should read Bill Whitlock’s AES paper"An Overview of Audio System Grounding and Interfacing" available here https://centralindianaaes.files.wor... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 @jcder, everyone is going to recommend his own pre in answer to your question. Here are a couple to consider: There is a Hovland HP-100 listed on Audiogon right now (at an asking price of $2350), a fine line stage (I heard it in Brooks Be... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @pryso Roger, really appreciate your efforts with this post. But, a question -"Over 100 watts is only justified by either high listening levels or insensitive speakers or both together. Excess headroom is a myth."I and many others find headroom s... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @amb3cog I’m willing to bet that Burning Amp alone will help. I know you can’t just spend, spend, spend, but maybe some directed advertising on Facebook towards people that are very interested in learning electronics would help. You might pick up ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @georgehifi I think that one comes later for free on line, as I’m such a tight arse, I only read the ones Stereophile drip feeds online for free. But it must be bad to beat the Leben CS300, check out the HF boost because either the output transfo... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @terry9 Thank you for your interest, Roger. I take your comments in the helpful spirit in which they were given.You have motivated me to look again at the stock Quads, and think about driving them with my current amps. These amps have proven them... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Great posts in here!i get my info directly from Steve McCormack,im watching this convo like a hawk.thak you say hi to steve for me | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @terry9 What I see in Plitron (theoretically) is two things: first, the two plates of the ESL are driven by the same core, so they can be precisely balanced; and second, they offer 75:1 step-up instead of 250:1. Since I committed to 75:1 with 25V ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @georgehifi Hey George, did you see the review of the Cary SLI-100 in the lastest issue? Why would they be so dumb to send an amp that is going to look so bad on JA's well documented test procedure? Read Dec, pg 91. Read pg 153 for Cary's respons... |
