| Does anyone care to ask an amplifier designer a technical question? My door is open. @unrecievedogma Hi ramtubes,thank you for that and here’s a followup. If triodes are low impedance and OTLs like high impedance, what was Jon doing then when he switched the OTLs to triode?i can tell you that the amps sound better after the conver... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @rsf07 I wish I could tell you more on the specs of the speaker but there's little info. Roger Sanders does use a dbx Venue360 DSP unit he modifies (there are no crossovers or transformers in the speakers that I'm aware of). When you say "direct ... | |
| Does impedance of a speaker change when one bi-amps? @byfwyneSo the bottom line is that there seems to be something to be said for light loading. It was rather obvious to me from the start. The tubes love it.Does anyone have any questions about why it works so well? The distortion reduction is usua... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @tomic601 i have been considering the 60 wpc kits Ralph puts out...thanks also for your participation here also..The M60 is a nicely laid out amplifier, spacious inside, easy to build for even a first times. Chassis and parts are nice. One sugge... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @maplegrovemusic Roger - I own a pair of king sound - King v1 and a pair of King sound ks17 . This direct drive amp you spoke of , how does that work ? do I have to bypass the step up transformers , and do the speakers need to be modified to use... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @wolf_garcia On another note, neither of my current fave tube guitar amps has a "standby" switch as they’re relatively low powered (18 and 15 watts respectively), so the question is: When can I get my beer? Another question I’ve asked elsewhere i... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @cakyo..I am building a symmetric plus/minus 70 volts dc (2 x 50 volt ac secondaries) power supply for an amplifier I am building. Mechanical issues are giving me more trouble than electronics such as drilling holes accurately etc. To this end, I ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 Roger, I think you provided this information somewhere, but I can't remember where, and can't find it. So let me ask you: what is a good output impedance number to shoot for in a power amp? How low does it need to be to prevent frequency ... | |
| Does impedance of a speaker change when one bi-amps? @steve59 WOW, you guys complicated that conversation.My Integrated amp rated at 250/8-425/4 shut down driving my power hungry speakers that have 2 pair of binding posts on back they’re 4 way 6 ohm rated and manufacturer recommends 500 watts. My ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @rsf507 Great, great, great thread! Ramtubes can you tell us what amps would be good to drive the Sanders 10e electrostatic speakers? I would like to know the capacitance of the panel itself, the electrode spacing and the polarizing voltage. D... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @stfoth RM, thank you for taking the time for this discussion. It's really, really refreshing.Turning back to my prior question about your thoughts on Dennis Had and his legacy Cary gear...sorry to bother if you are not familiar (https://www.car... | |
| Does impedance of a speaker change when one bi-amps? @imhififan IMO, parametric equalizer pair with active crossover can make a huge improvement! I like the crossover of course. Many audiophiles will shy away from the EQ. I see no need in adding anything digital either. One can easily select a c... | |
| Does impedance of a speaker change when one bi-amps? @erik_squires Hi, Ive been reading your blog. Do you really feel this way about stereophile. Hearing aids? Trick? What is the "stereophile curve"? For a long time I've had trouble matching up Stereophile reviews with my experience of the same sp... | |
| Does impedance of a speaker change when one bi-amps? @bdp24 Being able to get rid of the speaker-level crossover parts is one of the two reasons for bi-amping (doing so has at least the potential for producing a worthwhile improvement in the sound quality of a loudspeaker). The other is, as Roger ... | |
| Does impedance of a speaker change when one bi-amps? @erik_squires bdp24 said.. Beside the advantage of a bi-amped speaker presenting an impedance of less variation to each of the two power amps than one amp sees from a non-bi-amped speakerThis is what I think he is saying. The advantage of a bi-a... |
