tube amps and electrostatics I recieved an email from Rodger. (below in parentheses)Roger Sanders ESL and amp guru is not one to get into heated debates on forums, this is why he has presented his white paper on the subject as simply as he knew how, so it can do the talking f... | |
tube amps and electrostatics Some cannot see the forest for the trees. Martin Logan ESL Montise sterophile review, driven by Audioplax 80w tube monoblocks, also by ProLogue tube Premiums, and then by Simaudio Moon Evo 7's solid state.Quote from the measurements by JA: "The sh... | |
tube amps and electrostatics "That, coupled with the normal brightness associated with solid state amps'That is a massive overgeneralization, and should be totally ignored."its easy to see why- it is common that the amplifier will be trying to make nearly 10x more power at 20... | |
Best Amp For Maggies 1.6 Tube Or SS Philjolet: "George I tried Rogue 120M with the 1.6 and it was lifeless, it was not a good match imo"They are far removed from the norm sound of a tube, as they have a good deal of feedaback and also use a feedward type of arrangement with conjucti... | |
tube amps and electrostatics Mapman, most Class D's I know off and some I have tested are greatly troubled by loads that go under 3-4ohms, and ESL's can dip to below 1ohm.Cheers George | |
tube amps and electrostatics No he didn't he, used the word "increased emphasis" where he should have used the word "linear", as in flat in regard to frequency response.Cheers George | |
tube amps and electrostatics Just the Quad ESL57 impedance curve, my ML's and Acousats are even worse when I measured their impedances.http://www.quadesl.com/quad_main.htmland add to this the highly capacitive nature of ESL's, and you can see why Roger Sander says Solid State... | |
Best Amp For Maggies 1.6 Tube Or SS The Maggie 1.6 have a very benign 4ohm load but a low sensitivity of 83db, a good Solid State amp of 100-200w that can do 4ohm on it ear should be a good choice.http://www.stereophile.com/content/magnepan-magneplanar-mg16qr-loudspeaker-measurement... | |
tube amps and electrostatics "Frogman: Georgelofi, thanks for the link and I am glad that you found what works for you."Like I said, I even liked the sound of tubes into ESL's, but when you hear the extension and dynamic presence that's missing with tubes once you've heard a ... | |
tube amps and electrostatics Frogman: You know I hope that most SS amps have a lower output impedance than most tube amps.Here is a quote from Roger Sanders of ESL fame a white paper on Solid State v Tubes for ESL's."This impedance problem is relatively minor when dealing wit... | |
Preamp for Art Jota Yes do your home work and Google the different sounds tube nuts say that different makes of 6DJ8's can have. From memory stay away from the European NOS Telefunken and Amprex as they have a more etched sound, the English Mullards and Brimar, and m... | |
tube amps and electrostatics Frogman: "original Quads driven by Levinson ML2 sounded very good."And what you would have also heard was a more defined and extended treble because those quads and these (ML's Acustats and other els's) go below 1ohm in the treble and start that i... | |
Preamp for Art Jota Michael the Jota is very high sensitvity, it only needs 400mV in to give it's full output just before it distorts. Most sources these day are well over 2v (2000mV) out. So as you can see it doesn't need an active premap with even more gain. Even a... | |
Anyone have/ordered the Job 225? Quote from the Jazz Times review:Speakers can take up to several hundred hours of playing time to begin sounding their best. However, as soon as I had the Nines up and running, I had to call DeVore to tell him that these were the most outstanding ... | |
Mechanical Hum from Class A Amplifier Clayton If the Class A bias is higher on one amp it will be hotter, and if it is bias higher than the specs then it will stress the transformer and cause it to hum. It needs to be looked at, do not play it. I have seen a transformer damaged because the bi... |
