Do you believe in Magic?
I honestly don't know if I'm a Believer or a Skeptic.Hi Bryon,That is a good thing, as I see it, because IMO the positions at both ends of the ideological spectrum are fundamentally flawed in numerous ways (that I won’t belabor here), and go hand-... 
Tube table top radios
eBay has a category devoted to tube radios, as a sub-category within Collectibles/Radio-Phonograph-TV-Phone/Radios. As you'll see, several thousand sets are typically offered at any given time.Also, check out the site of Antique Radio Classified. ... 
Mcintosh with Ayre pre-amp
The output impedance of the Ayre preamp is quite low, and will be far lower than, and therefore completely compatible with, the input impedance of virtually any power amp, including the ones you are considering.Regarding your recent thread about h... 
What's a 30-year old Grace F9-E Ruby worth?
Isochronism, LOL! Thanks!Best regards,-- Al 
No, You Cannot Bi-Amp
JohnK, thanks for your comment. To be sure it's clear to everyone, I'll repeat that the issue I cited, involving a large disparity in power capability between the high frequency amp and the low frequency amp, just applies to PASSIVE biamping, in w... 
No, You Cannot Bi-Amp
01-21-12: MagfanI'm sorry, but the power relative power needed IS governed by the crossover frequency.... The amp will only have to produce power for those frequencies for which the speaker has a need....Hi Magfan,Somehow my point isn't coming acr... 
How many enjoy low $ second system sound?
One of the systems I have in my house consists of a Radiocraftsmen 10 tuner (from 1952, purchased by me about 20 years ago for $25), an H. H. Scott 299C integrated amplifer (from about 1961, purchased by me about 20 years ago for $10 plus what I h... 
Protocol on mixing -10db and +4db line levels
I wouldn't worry about the difference in line-level standards. "+4 db" undoubtedly refers to +4 dbu, which is a line-level standard for professional equipment, and which corresponds to about 1.23 volts. A consumer-oriented cd player or other digit... 
No, You Cannot Bi-Amp
01-20-12: MagfanRelative power needed is almost entirely governed by crossover point.If you crossed over at 10khz, you could make due with a 30 watt tube amp on top of a 300 watt SS. Than, other issues would come to the fore.Right! A major "other ... 
No, You Cannot Bi-Amp
Some good points have been made above. With respect to passive biamping, another commonly overlooked point is that in that arrangement both the high frequency amp and the low frequency amp have to output the voltage range of the full range signal....

Re Elizabeth's statement: Bombaywalla, I know that you have considerable technical expertise and relevant experience, but upon careful reading I don't see anything unreasonable or technically implausible about Elizabeth's statement. In its essence... 
What's a 30-year old Grace F9-E Ruby worth?
I've used a Grace F9E as my primary cartridge since 1979. I purchased it originally as the non-ruby version, upgraded it with a ruby stylus several years later, and had it retipped/rebuilt by Soundsmith in 2010 (the $250 option Mr. Ledermann offer... 
Digital XLR vs. Analog XLR - Balanced Cables
01-17-12: Renato13Ok...So in a pistachio shell, say you have the option to use either an AES/EBU digital 110 ohm cable OUT from a USB to SPDIF converter to a WYRED4SOUND DAC2 AES/EBU input OR a 75 ohm digital SPDIF interconnect from same USB to SP... 
Lightspeed Attenuator - Best Preamp Ever?
Given George's good answer about noise level, and his answer implying that the "line regulation" performance of the internal 5V regulator is good enough to reduce expectable variations in the 12V input to the point that they would not result in a ... 
Sota+SME IV=Ugh !!!
Hi Randy,The arm was (and still is) a Magnepan Unitrac. I'm not completely certain as to whether or not the arm may have played a role in the hum, but my guess is that it did not. Although it doesn't necessarily signify anything conclusive about t...
