Speakers for aging audiophiles - What's with today bass emphasis ?
marklings—Yes, you're likely correct about digital popular music mixes being more bass heavy than when intended for vinyl media, but that's for good reason. LP discs are the product of a 1948 compromise that traded fidelity for the means to fit 25... 
CDs Vs LPs
The “vinyl revival” is a cult-inspired (and dealer-propelled) specious fad. It’s best ignored unless (a) you already own lots (and lots!) of LP records, or (b) you’re socially coerced to support the groupthink (https://en.wikipedia.org/wiki/Groupt... 
We give up perspective to avoid tone controls
prof—OK, let's go: First, make certain that both of your e110 subs are free of a common component failure (bad or intermittent input level pot) that plagued many e110 plate amplifiers. Turn the input level gain all of the way down, and connect an ... 
We give up perspective to avoid tone controls
prof—I certainly CAN help you with this; I own a pair of JL Audio E110 subs myself, and use a Marchand XM66 active crossover, which is functionally equivalent to JL Audio's CR-1, but lots cheaper (has lower quality internal components). However, I... 
We give up perspective to avoid tone controls
prof—I'll try to help. It sounds as if you've got TWO separate subwoofers. Correct? What make/model are these subwoofers? And are these subs self-powered, with their own (independent) internal power amplifiers? If not self-powered, how do feed aud... 
We give up perspective to avoid tone controls
E—Thanks for such comprehensive clarity; I generally concur. But my simple comment (that it's easier to phase-match subwoofers-to-main speakers when all speakers are sealed, not ported) was never intended to apply to idealized environs filled with... 
We give up perspective to avoid tone controls
 @ erik squires—Phase matching of subs-to-mains should always be optimized at the applicable crossover frequency, and the measurement point to define the match should be located (precisely) at the intended listening position. When ported speakers ... 
We give up perspective to avoid tone controls
After 5+ decades of heavy DIY audio experience, I conclude that conventionally implemented (preamp) tone controls introduce too many inaccuracies to prove generally acceptable. Virtually all such circuits cause significant channel tracking imbalan... 
Does anyone leave their amp and preamp on all the time?
On those voracious vacuum tube power amps…I’m no model “Mr. Green” when it comes to conservation, but I’m sufficiently astute to recognize that some vacuum tube power amplifiers so exceed the bounds of tolerable waste that they merit special disti... 
Tube or Trasistor
atmosphere--- Let's slow down here and try to work together. I could have expressed myself better on some points, so...On tubes vs. solid state specifications: Yes, all active devices do have variances, and, having built numerous of my own preamps... 
Tube or Trasistor
oddiofyl---Don't depend on that! The medium income for full time professional musicians isn't a lot more than the medium household income for the U.S. population as a whole: About $59,500 annually. Distinguished full time members of civic symphony... 
Tube or Trasistor
cleeds---when I last attempted to determine the remaining manufacturers of (receiving type) vacuum tubes some 18 months ago, there were zero based in the USA. That's fact. You now indicate that "Domestic tube manufacturing lives." WHERE does it li... 
Tube or Trasistor
Regarding "How do you account for the many high quality and rock-stable vacuum tube products now being manufactured?"---The point is that there are NOT many vacuum tube products now being manufactured. World-wide, receiving-type vacuum tube produc... 
Tube or Trasistor
As duly noted: "The entire world market for (receiving-type) tubes is now confined to a small coterie of audio and guitar buffs..."Guitar amplifiers are often (intentionally) over-driven into clipping overload, where their predominant even order h... 
Tube or Trasistor
On vacuum tubes—then and now…I returned from draft duty in early ’54, and from that time on I’ve been absorbed with high fidelity audio. Of course, the early years meant embracing vacuum tubes. Transistors weren’t ready for prime time, so tubes we...
