Dec 17, 2004	Home Spindle Lube Test Inpep: By reducing wear on the mating surfaces as you described, the lubricant reduces friction that could be transferred into the platter. It also mimizes the associated the loss of energy due to the reduction of mechanical binding and / or therm...
Dec 17, 2004	amp for infiinity kappa 9 I sincerely doubt that someone will list their Sunfire's as having "the Apogee mod" as that is what Robert Levy of Sunfire refers to them as. Sunfire's technical dept calls this their "thermal and high current update". Good luck finding used model...
Dec 17, 2004	I'm Very SCARED - Please advise, Cartridge Drop I would be more concerned with a bent or twisted cantilever than i would damage to the suspension. If anything, the stress to the suspension may have "sped up" break-in time. The twisting or bending of the cantilever is another matter unto itself....
Dec 16, 2004	"High Current" Keis: Your comment makes it look like high rail voltages have the potential to suffer more than a lower rail voltage. That simply is NOT the truth. ALL voltages collapse under demand IF there is a lack of current. The use of a higher impedance loa...
Dec 16, 2004	Home Spindle Lube Test Inpep: I just went back and re-read your explanation. It makes perfect sense to me and i have nothing to argue with you about on this. In fact, i would even go further in saying that one can use too heavy of a viscosity lubricant, which would resu...
Dec 16, 2004	"High Current" Morbius: Those are typical factory specs, nothing like what we are discussing here. On top of that, the voltage swing on that specific Krell is pretty low at their rated 138 v peak to peak. My Perreaux PMF-3150, which is also rated at 300 wpc @ 8 ...
Dec 16, 2004	Back into vinyl - part 1 I don't doubt that moving the power supply away from the TT is a good thing. I would also think that placing large filter caps inside of the TT itself would provide the instantaneous demands that the motor might need. You get less motor vibration ...
Dec 16, 2004	amp for infiinity kappa 9 I used a completely factory refurbished Bryston 4B on some speakers that are also low impedance and very insensitive. Not only did it not sound good, it was constantly going into clipping. I would highly recommend that you NOT use one of these amp...
Dec 15, 2004	Who will survive? One last table til I die. I still haven't had a chance to read the articles, but i just want to ask you folks one question. That is, where do you think the technology came from in order to start mass producing solid state devices? I'll give you a hint. They probably didn't...
Dec 15, 2004	"High Current" The Sunfire amps can do this with enough AC and the right internal fusing. I've got test results from an old magazine review on one of the original Sunfire's that verifies this. I'm not saying that i consider the Sunfire's to be the "best built" (...
Dec 15, 2004	Back into vinyl - part 1 In the RF industry, we super-impose RF onto DC all the time. The use of an unshielded wire and / or a cable that uses a highly inductive geometry in this situation is something that i would take issue with. At the same time though, you don't want ...
Dec 15, 2004	"High Current" All of this comes back to how the manufacturer wants to market the product and how the marketing department thinks will be the most effective manner at achieving those goals. Given that i've seen amps rated at 200 wpc @ 8 ohms clip at 280 wpc, the...
Dec 15, 2004	amp for infiinity kappa 9 I should have mentioned that this speaker stays below 3 ohms from 60 Hz and below. Given that you already need high levels of power to control a large woofer as it is, compounding that demand with a very low impedance at that point is pretty rough...
Dec 15, 2004	amp for infiinity kappa 9 Given that this speaker dips to .8 of an ohm at appr 33 Hz and .9 of an ohm at appr 7.2 KHz, you need a MASSIVELY powerful amp that can deal with huge current demands at both ends of the audio spectrum simultaneously. With that in mind, i would su...
Dec 15, 2004	Van Alstine Longhorn Cartridge? The first modified Grado that i'm aware of was made by Bill Seneca and sold under the name of "Promethean" for $135. This was the cheapest Grado available at the time and Bill performed several different mods to improve it. After modifications, it...
