| Tone, Tone, Tone ! @mijostyn, you sound like the guys on the Home Theater Subwoofer sites. They too consider the SPL output capability of a sub as the only criteria with which to assess it’s quality. Linkwitz and Richie/Ding designed their OB/Dipole subs for the rep... | |
| What are the advantages to a Class A amp & what are the trade offs? @artemus_5, I would have my 100w version modified to run in Class A, but it is powering a loudspeaker which contains magnetic-planar drivers, known for their very low sensitivity. Not as much so as Maggies, but close.I for years used a 25w/ch Clas... | |
| Tone, Tone, Tone ! A 3dB boost at 20Hz is NOT a shelving circuit. A shelving circuit is a progressive low-pass compensation filter, not a static figure (6dB/octave, the boost therefore increasing as frequency decreases), which exactly compensates for the 6dB/octave ... | |
| Tone, Tone, Tone ! @mijostyn, what were the dimensions of your OB/Dipole sub frames? Were they H-frames, or W-frames? Linkwitz chose to go with the W, Danny Richie with the H (though he provides plans for both on his GR Research website).Did you incorporate the mand... | |
| Tone, Tone, Tone ! Actually, though most of Doug Sax's work was as a mastering engineer, he DID do some recording, including the Sheffield Direct-To-Disk albums. On those he was recording AND mastering engineer, mastering of course as the recording was taking place. | |
| What are the advantages to a Class A amp & what are the trade offs? There is one maker of a well-regarded tube power amp (I’ll allow he and it to remain anonymous, so as to not appear to be "pushing" them) who offers the amp in both Class-A/B form, and in pure Class-A. Both versions share the same circuit architec... | |
| Tone, Tone, Tone ! Speaking of transparency.....it was when I read Harry Pearson say in a review of a loudspeaker that it was "transparent in the same way the original is" that I realized he didn’t actually understand what the term transparent means. If the original... | |
| Tone, Tone, Tone ! @mijostyn, Siegfried Linkwitz disagreed (R.I.P.) with you ;-). Have you actually ever heard an OB/Dipole sub, or are you speaking in purely theoretical terms?Rythmik's Brian Ding, even though collaborating with Danny Richie on the OB/Dipole Sub (i... | |
| Any Magnepan Mini Maggies fans here Do you know about the Planar Speaker Asylum? There is lots of discussion there on that subject by Maggie owners. | |
| Tone, Tone, Tone ! There are those who still feel the best bass QUALITY they ever heard was that produced by the two bass panels of the Magneplanar Tympani loudspeakers; the original T-I up through the final Tympani, the T-IVa. The T-IVa (upon which the new MG30.7 b... | |
| Tone, Tone, Tone ! @prof, I too have heard that "ghostly sound" from planars (most recently a pair of Maggie 1.7’s), but that can be and often is a result of comb-filtering caused by the back wave of the speaker bouncing off the wall behind it, meeting up with the f... | |
| So I switched from XLR cables... Great Captain, the Parasound conforms to the AES standard. Now how ’bout the Mac? | |
| As good as it gets? Or, it’s still selling well enough that there is no economic motive to change it. Hi-Fi companies can be more cynical than one may think. ;-) | |
| So I switched from XLR cables... All true and valid points, Al. The balanced outputs in Tim de Paravicini’s EAR-Yoshino 868 pre-amp are created via output transformers (rather than integrated circuits or, heaven forbid, opamps)---which are widely used in recording studios, in whi... | |
| Arm interconnects choice??? For the cost of even a modestly-priced high-end ic, you can have your arm rewired in a single uninterrupted run from cartridge tags to RCA plugs. The output of phono cartridges is absurdly low, so solder joints, jacks, plugs, etc. are to be avoide... |
