| Does anyone care to ask an amplifier designer a technical question? My door is open. @atmasphere Hey Ralph Roger, I think if you revisit the above comments you will find them to be incorrect. An OTL has to be able to drive real world loudspeakers and so can produce the same currents at the output as any other amplifier. FWIW, the... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @krelldreamsAt your listening levels an RM-10 would do the job. I need to talk with my salesperson about arranging an in home demo. The RM-10 now has a beautiful but expensive wood base which I would not like to have go back and forth. The RM-10 i... | |

| Does anyone care to ask an amplifier designer a technical question? My door is open. @tomic601 first thanks for the input on Ralphs amp, speakers likely the dead ESL-63 I mentioned in another post. I am away from them but I am assuming with ago all the panels are toast, the limited fault tree look I have done so far indicates EH... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 Roger I happened to make my first visit to a new hi-fi shop just opening in Livermore, CA in 1973, Audio Arts. It was a 1-man shop, that man being Walter Davies, now the maker of the great Last Record Care products. And as luck would have ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @fleschler Funny that the latest ARC amps I've heard sound greyish, muted dynamics, etc. My friend has an ARC 75 which is no match for his Classic 60s or my voltage regulated amps. Worse, his amps, Ref 5 preamp and $10K CD player all have ha... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @unrecievedogma I think the debate between cone and electrostatic is reminding me of the great cable interconnect debate. Could it be that this is just personal preference? Or even that my ears are just trained and accustomed to whatever cones do... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @shkong I really like the sound of SET over PP.You can see my audio history in the below link.https://forum.audiogon.com/discussions/the-most-musical-sound-in-my-40-year-s-audio-historyThanks again for your kind advice SE amps are often great with... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 Thanks for the compliment and notes on the RM-200.I was also introduced to the Tympani speakers in 1973-4. At the time this product could only be bought from ARC dealers and was essentially a speaker that Jim made for Bill. Both were just s... | |
| Does impedance of a speaker change when one bi-amps? @steve59 I found a review at Sound Stage mag. Looks like a nice amp. This is interesting, from the review https://www.soundstagehifi.com/index.php/equipment-reviews/934-hegel-music-systems-h360-dac-integrat... Like its predecessor, the H360 boa... | |
| Does impedance of a speaker change when one bi-amps? @shkong78 Yes, turn them off when not listening. The cap died due to continued high temperature. Electrolytic caps do that. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @fsonicsmith you can’t possibly mean that preamps are easier in general and I am unaware of any accolades for your preamps (whereas you are lauded for your amps). Obviously you mean that for your tastes and purposes, preamps are easier than amps.... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @unreceivedogma By “more power” I’m just going by where I set the volume control before and after. It was a surprise, as I thought there would be less, and I was pleased because in my layman’s view it meant less stress on the tubes and circuitry.... | |
| Does impedance of a speaker change when one bi-amps? For the record, almost all passive crossovers also include some form of EQ. If you plan to remove and replace a passive crossover you need to be prepared to do both. A local speaker builder brought over a pair of his speakers without crossover ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @mapman I figured it out by listening and trial and error over time and based essentially on those parameters as a guide. However specifications alone seldom tell the whole story. The devil is always in the details much of which is never specifi... |
