Dec 23, 2014	Do wooden arms warp Honest, guys, this issue needs to be put to death. Whether "they" warp or not, and I don't doubt that wood tonearms are susceptible to warping, some wood tonearms are among the best I've ever heard, to include the Talea and the Reed. Vacuum tubes ...
Dec 22, 2014	LCR phono stages we know about Thekong, Thanks for mentioning the Thomas Mayer LCR phono stages. I had been meaning to do so as well. He seems to sell an LCR phono in kit form, using Dave Slagle LCR modules (aka "Intactaudio"). Very tempting. As to this shoot-out, it is not ver...
Dec 22, 2014	Windfield Cartridge Do you refer to the Ortofon of that name?If so, I own an MC7500, father to the Windfield which is father to the A90 which is father to the Anna (or maybe I missed one in this lineage). The MC7500 is a very neutral cartridge that I like very much.
Dec 22, 2014	LCR phono stages we know about Good point. That's where Dave Slagle jumped in, to design and build chokes that will work well in "high-impedance" LCR designs. Dave can create very precise modules.One of our readers has done a little digging into the Emia phono stage. Apparently...
Dec 20, 2014	LCR phono stages we know about Yes, that's one problem with designing a tube-based LCR; the needed 600-ohm impedance on the input side is hard to achieve with tubes. There are many interesting threads on that subject. One such claimed that you only need 600 ohms on one side of ...
Dec 18, 2014	LCR phono stages we know about Dave, I looked it up. Not much info regarding the innards. Seems to be solid state. Does not seem to have adjustment for load R and C. However, it does have a mono switch. (I don't know how you can build a phono stage with high end pretensions and...
Dec 17, 2014	LCR phono stages we know about Addendum. After composing that long treatise, I did some surfing to find out more about the Slagle LCR phono stage owned by my neighbor. It turns out that the phono stage is called "Emia" and is marketed by Dave and Jeffrey Jackson, in collaborati...
Dec 17, 2014	LCR phono stages we know about Jazdom, Hi. Can you say more about the Kahn phono stage. I presume the name refers to our mutual friend in Silver Spring. But maybe not. John, I own a Silvaweld phono stage, designed and produced by the same Mr. Park who later went on to produce t...
Dec 16, 2014	Would vinyl even be invented today? Jafreeman, It's all about evolution. These technologies come and go (and come) in a natural order based on perceived need and science, and lately, nostalgia.
Dec 16, 2014	LCR phono stages we know about John, I am very familiar with your association to K&K. I agree they make very fine products. However, what has any of that got to do with the price of eggs or the topic of this thread? I guess I can be faulted for not having catalogued every p...
Dec 15, 2014	LCR phono stages we know about That's not quite correct or at least possibly confusing as written, Sqlsavior.LCR vs RC has nothing to do with active vs passive RIAA. Either technique can be implemented in a passive RIAA filter. It's just a matter of how the filter is created, w...
Dec 15, 2014	Dynavector DV-507 Mk II ? Verybig and Carl, Your comments are useless to anyone contemplating a purchase. I think it would be fair to say that the DV tonearms are fundamentally different in design and execution from standard pivoted tonearms. The differences afford certain...
Dec 15, 2014	LCR phono stages we know about Mordante et al, I apologize for not defining the acronym. I thought most analog aficionados would know about LCR RIAA circuits. But here goes a definition:In analog history, nearly every commercial phono stage has been based on using RC filters to...
Dec 14, 2014	Modified Lenco vs TW Raven Gilles, The plinth in the photo looks to be made of layers of MDF, not alu. However, Jacques does mention that he is going to build one out of a solid block of alu, which must be the one you bought(?)FWIW, I really really do not like the sound of ...
Dec 13, 2014	Who needs a MM cartridge type when we have MC? On the subject of VTF in particular and cartridges in general, you guys might want to read the summary of a talk given by Mitchell Cotter to the Boston Audio Society in 1977, when men were men.Here.You need to scroll down until you find the summar...
