| Tube Amp for Martin Logan Speakers Unsound: I just looked at the Snapper owners manual, and it states the output impedance is 1.5ohm, so the tap is less than 8ohms but more than true 4ohms. This 1.5ohms output impedance was also measured and verified by Sound and Vision review of t... | |
| Tube Amp for Martin Logan Speakers Bifwynne, the Manley Snapper from the website looks as though it has 1 set of 8ohm speaker terminals?. It states in the specs that it's damping factor is 4.7 (into 8ohms?) which would mean it's output impedance is around 1.7ohms. If it's a 4ohm ta... | |
| Narrowing on suitable amp for Martin Logan CLX Any amp that can give good current drive in these loads from 20hz to 20khz and stay flat with it's frequency response would be the amp to consider (look at the bottom of the page for the impedance graph in the link)The CLX range from 100ohms in th... | |
| Tube Amp for Martin Logan Speakers I certainly did not derail the topic Atmasphere, the OP asked for suggestions for tube amps to go with his Martin Logan speakers. I simply mentioned in my first post that they are a difficult load, no mention ever of him getting a SS amp ever, you... | |
| Tube Amp for Martin Logan Speakers You'd be far better off saving the $1140us for the Zero's and putting towards the right amp or speakers, instead of masking the problem with the Zero's, which itself has it's own set of problems.Cheers George | |
| Tube Amp for Martin Logan Speakers 03-31-14: Tomcy6Of course not every amp can handle the job when you've got a speaker that has an impedance of .5 ohms at 20khz. But you don't need a lot of power to reproduce most musical content at 20khz either.True, but if the amp cannot keep co... | |
| Tube Amp for Martin Logan Speakers 03-30-14: Tomcy6Someone should tell Martin Logan about all this. Those idiots are telling people that their speakers can be used with a wide variety of tube and solid state amps.Some tubes can drive them without becomming too much of a "fixed tone... | |
| Tube Amp for Martin Logan Speakers 03-29-14: Tomcy6I think that ML designed their current line to be used with either tube or ss amps, the choice being the user's.Yet if you Google images for previous big HiFi shows, and look at specific Martin Logan rooms demo's, as far as I saw n... | |
| Tube Amp for Martin Logan Speakers I used to build many SS Class A amps some water cooled back in the 80's 90's they were along the same lines as the ML ML2's but stereo and not such a "bomb or hydroelectric plant" as you guys put it. But they could almost double as well all the wa... | |
| Tube Amp for Martin Logan Speakers Like a pair of these classic, Class A Mark Levinson ML2's 25w monoblocks.http://www.wtconcept.com/levinsonml2/ 25w into 8ohm 50w into 4ohm100w into 2ohm200w into 1ohm400w into .5ohmThere's 20watts and then there's 20watts, "no tone control behavio... | |
| Tube Amp for Martin Logan Speakers Mapman, I just noticed that you have class D amps as powerful as they are don't think they are out of the woods when it comes to driving ESL's Their achilees heel is driving low impedances in high frequencies, they behave in a similar fashion. Jus... | |
| Tube Amp for Martin Logan Speakers 03-28-14: MapmanMy understanding is low impedance in treble region does not present nearly as much of a challenge as same in bass in that exponentially less power is needed for flat treble response. I think that is the main reason why tube amps ca... | |
| Tube Amp for Martin Logan Speakers That's because the McIntosh 275 has quite a low output impedance for a tube P/P amp at .57ohms from the 8ohm tap.(probably has a fare amount of negative feedback)But the Montis would still be a hard load for many amps as John Alexander's measureme... | |
| Tube Amp for Martin Logan Speakers With the Quad 2805's your AR Ref 150 would be fine on the 4ohm tap as they are below 1ohm output impedance, maybe not so on the ML Monolith's http://www.stereophile.com/content/audio-research-reference-150-power-amplifier-measurementsCheers George | |
| Tube Amp for Martin Logan Speakers Hi Bruce the Quad are not too bad http://www.stereophile.com/images/66Quadfig01.jpgwhen you look at the ML Monolith'http://www.martinloganowners.com/forum/showthread.php?6301-Impedance-curver-graph&p=69831&viewfull=1#post69831Cheers George |
