How do you judge your system's neutrality?
Newbee: This thread has been a valuable learning experience for a lot of folks IMHO.Dgarretson: This thread evidenced clear articulation of at least several new constructs. It was a refreshing change from the repetitiveness of many subjects posted... 
cd player + preamp = too much gain
Hi Vaughan,I would not recommend either of those devices.The "Peripheral" is intended for car audio and sells for only $16, and appears to have nickel-plated connectors. Enough said!The Alva is intended for use with pro equipment, and therefore ma... 
The Hub: Futterman H3: Seen one lately?
Fascinating reading!Here is a link to a site that appears to present good background on the Circlotron topology, on its Electro-Voice incarnations in the mid-50's, and on the several different related patents that were granted and/or applied for a... 
Ia a good amp more important than a good DAC?
"rationale"?Yes, that's correct. "Rational" is also a word, but it has a different meaning.http://www.merriam-webster.com/dictionary/rationalehttp://www.merriam-webster.com/dictionary/rationalMark -- I don't question that for many people "source f... 
Ia a good amp more important than a good DAC?
Honest1: I have found the system sounds no better than the weakest link.I agree. The often stated rationale for "source first," that the imperfections of what comes first in the chain cannot be undone by what comes later, makes no sense because it... 
The first-best-last analog item you ever bought
REL (Radio Engineering Laboratories) Precedent FM tuner, from 1954! Purchased by me in 1991, and used in conjunction with an H. H. Scott LM35 multiplex adapter for stereo.Regards,-- Al 
cd player + preamp = too much gain
Hi Vaughan,I would suspect that the Goldenjacks and the Rothwells (and any other similar attenuators) all differ somewhat in terms of the resistor values that the designers chose, and possibly also in their internal circuit configurations. Those d... 
inexpensive xlr cables for JL 113 subs
Cable selection for this purpose should be much less critical than for connections between line level components, since effects on the mid and high frequency components of the signals won't matter.The Blue Jeans should do fine. Another good choice... 
cd player + preamp = too much gain
Hi Vaughan,Did you use good quality attenuators, such as the Rothwell's?Did you use them at the end of the interconnect cables (i.e., at input jacks and not at output jacks)? The Rothwell's are designed to be used in that manner, and even apart fr... 
Whats your current Reference CD at the moment?
Chesky CD31, Dvorak's "New World Symphony," The Royal Philharmonic Orchestra conducted by Jascha Horenstein (recorded in 1962, which you won't believe if you hear it!).Sheffield Lab, Prokofiev's "Romeo and Juliet," The Los Angeles Philharmonic Orc... 
Will using bothA and B spkr out half amps power?
Your NAD, like most solid state amps, undoubtedly has a very low output impedance (likely a very small fraction of an ohm). As a consequence of that it will "try" to put out a voltage waveform that is proportional to the music signal going into it... 
Who has dumped the power conditioner?
Hi Bryan,You didn't miss reading what I was referring to, but my interpretation of it was different. He is saying that what will only occur under a rare combination of circumstances is COMPLETE cancellation of ac-related inter-chassis currents (wh... 
Length of speaker cable effect bass response?
I second HifiTime's question. If the speakers are wired out of phase relative to one another, or if the low frequency and mid/hi frequency bi-wire connections to either speaker are reversed relative to one another, there will certainly be major au... 
Who has dumped the power conditioner?
Hi Bryan,No, the reference I linked to, and the comments I made, related to the unpredictability of the benefits (and possible lack of benefits) of converting normal unbalanced 120V AC to balanced 120V AC. So those issues will apply to the Equitec... 
Minimum Cart Output for 30db Gain Phonostage
Why not use a linestage after the phono stage and plug your headphones into the linestage, assuming it will add enough additional gain to drive them?Unless it has a specifically designated headphone output, a line stage preamp will usually not be ...
