| The pivoted arm experiment is over Lewm, I've not heard the Trans-Fi yet but I have customers that really like it. | |
| High Efficiency Speakers Your top 3 or more Most high efficiency speakers have fairly tight tolerances in the voice coil gap which makes them very reactive. The back EMF they present to amplifiers that use a lot of feedback is enough to confound the amplifier, as the feedback signal thus co... | |
| The pivoted arm experiment is over Mepearson, excellent work. I think you have shown what I have felt for a long time, which is that time has passed the FR arms by. I do not agree otherwise that this test is conclusive regarding your other thread, but if what you wrote is indeed wh... | |
| Reel to Reel A tape machine that is a bit of a sleeper is the Magnacord. They were made in 7 1/2 and 15 ips versions, although seems to me the 7 1/2 ips (with 3 3/4 as the slow speed) is a bit harder to find. There was the 724 and 1024; like any older machine ... | |
| Woofers Gone Wild Before you add a rumble filter, I would take a look at the specs of the cartridge and the effective mass of the arm. They should combine to create a mechanical resonance between 7 and 12 Hz. If you get outside that window (for example if your cart... | |
| High Efficiency Speakers Your top 3 or more I've heard the Classic Audio Loudspeaker, both T-1 and T-3 many times. The recent field-coil versions are remarkable. They are faster and just as detailed as the best electrostatics, yet very relaxed, and image easily. They are also very cohesive.... | |
| Magnepan 1.7 We recently did an installation with our M-60s are our local dealer who has the 1.7 in stock- so I heard it with our amps. IMO this is an excellent speaker and a nice upgrade from the prior 1.6; no doubt why this speaker has been big news as Magna... | |
| Amp or blocks for Total Eclipse The Total Eclipse is easy to drive. We can drive them with our smallest amp, but most of our customers usually use either our M-60 or MA-1 for them. The speaker makes good bass down into the lower 20s and we found it easy to set up. They are desig... | |
| Power output of tube amps compared to solid states Unsound, its not. Almost any service shop would have such gear though, you could easily set up this test at almost any one of them simply because the speaker and the amp really are of no consequence in the test- the results are that profound.How t... | |
| Power output of tube amps compared to solid states Unsound, seriously, just try the test I outlined above. It will eliminate any doubts you may have. When GE did their tests they found that people would not object to up to 30% THD- if it was all 2nd harmonic. But less than 0.1% of odd orders and t... | |
| Are linear tracking arms better than pivoted arms? Over the years I have been involved with a fair number of recordings, some of which have made it to LP, others CD only and still others that only exist as R2R. What I have found is that having a master tape to help me with evaluation is extremely ... | |
| Power output of tube amps compared to solid states I've only seen snipets but its easy to prove if you have some very basic test equipment.All you need is a sine/square wave generator, a small amp of any type, a VU meter and a speaker.Set up the sine to drive the amp, which is in turn driving the ... | |
| Making A Monoblock out of a VK-55 Ikonetic, I refer you to my earlier post- you will loose some delicacy. | |
| Are linear tracking arms better than pivoted arms? Cjfrbw, I agree with a lot of what you posted, I just don't think that should stop us as audiophiles/manufacturers or whatever from trying. I think intention plays a huge role- the guy that gets into a high end audio business to make money is ther... | |
| Making A Monoblock out of a VK-55 Right, Al, you can't use this technique with transistors!! They have to be bridged. Dynaco describes this monostrapping technique in the manual for their old Stereo 70. You do indeed get 2X the power. Since the output impedance is reduced (as seen... |
