| Dyanco Mk III's speaker suggestions Get something that is nominally 8 ohms (especially in the bass!) and has an efficiency of at least 91 db. That will take better advantage of the amp's abilities. | |
| Zero Negative Feedback Amps with High Power Jult52, when you say 'high power' how much do you mean? | |
| Dedicated circuit Just a FWIW: the way the equipment is designed relative to ground is a lot more important than the grounding in the building! | |
| Soundstage vs background noise? I appreciate all the comments. Ralph, my experience is that tubes are just noisier than solid state. Admittedly I do not listen to music with my ear 4 inches from the tweeter, but I have to tell you, at that close range I always heard a hiss throu... | |
| Zero Negative Feedback Amps with High Power You might want to read this:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpCan't agree with the post directly above, unless you include the idea that the amp is mismatched with the speaker. IME amps without feedback handle m... | |
| Preamp Headroom Question Ralph, I'm not sure I understand your comment either, especially the part about "in the latter case the noise should be less than that of the groove." Can you clarify? Did you mean "in the former case"?Also, why would playing an essentially silent... | |
| What ohm to set amp If you run an 8 ohm speaker on the 4 ohm tap there will be no reliability consequences, although it may not sound right (which is a different matter). | |
| Soundstage vs background noise? Tube amps, IME, rarely take a back seat to transistor amps when it comes to soundstage. So I am suspicious that there is something else going on- perhaps related to the noise you are talking about. You might want to test the smaller tubes in the a... | |
| Preamp Headroom Question The rule of thumb with any phono stage is not how much noise there is when you lift the tone arm off the LP, but how much noise there is when the needle is in a good silent groove.In the latter case the noise should be less than that of the groove... | |
| TriPlanar Tips FWIW the Triplanar protractor has not changed at all in the last 5 years. The protractor is not incorrect- it is intentionally built with a slight amount of slop and it is expected that the exact and final position of the arm will be corrected dur... | |
| What amp should I buy to power Martin Logan Esl's? FWIW tube amps can work extremely well with ESLs. The problem you run into sometimes (one that is common with ML ESLs) is that the impedance of the speaker has really been set up to favor transistor amps (i.e. are set to a lower impedance) more th... | |
| Putting together first system... clueless. If you are on a budget and you want tubes, its likely that you will not have a lot of power to spare. For this reason you want a speaker with greater efficiency, and for that reason I feel like a Magnaplanar would be a poor choice. Zus are popular... | |
| increase power amp sensitivity As Heyra has said, its going to be a lot easier to reduce the input to the bass amp than trying to increase the gain for the high frequency amp! | |
| Wish List For Vinyl Pressings So far the only LPs that have more than one entry are the Beatles and Emmy Lou Harris' 'Wrecking Ball'. Is this worth another thread yet?So much music! I am sure there are a lot of great suggestions here. Its my surmise that a Beatles reissue will... | |
| Fisher 500B Questions The 500B is notorious for the volume control not tracking properly and power switch problems. I've replaced many of them! |
