| Want more high frequency extension Mattybumpkin...If amplification is the problem I really think the power amp is probably the place to look. EL34 and KT88 tubes are pentodes, and I bet that there is local feedback from the transformer to the output tubes. "Zero Feedback" probably ... | |
| Living with popping and crackling Dougdeacon...No. For artistry I like my Rubinstein LP, which I play in preference to digital discs, but I am always upset by the surface noise. Even when new this LP was somewhat noisy because they cut it at a rather low level, probably to preserv... | |
| ?'s about quality of audiophile recordings I have not bought "audiophile" LPs, but in the case of digital discs, the ones that I have from certain European "audiophile" labels, and costing almost $30, are clearly superior to run-of-the-mill discs. | |
| Know any DIY spkr kits w/woofer driven full-range? You asked about any disadvantages. A woofer (or any driver for that matter) has very uneven frequency response, and poor off-axis response, as it approaches its high end frequency limit. It is best to silence the driver before it reaches this unev... | |
| Speaker connection for Maggie 3.6R My speaker wires have no terminations other than tinning of the strands, and are inserted into those "wretched little binding posts" which have set screws that firmly clamp the wires in place. I can't imagine how any slip-fit connector device coul... | |
| Want more high frequency extension It's hard to believe that the tubes would limit HF response...after all tubes are (or were) used for RF amplification. In a tube power amp the output transformer is the component that limits HF response, and a large amount of feedback around the t... | |
| Living with popping and crackling Jyprez...Recordings made prior to the digital age usually had a good deal of "processing", most notably Dolby or DBX. Also of interest is the almost universal use of multitrack recording with subsequent mixdown to stereo, which scrambles phasing, ... | |

| Living with popping and crackling Johnnantais...Congratulations!! You are one of those who can listen through the noise. | |
| Living with popping and crackling Papertrail...Some noise filters were much more effective than others, and used some very clever methods to distinguish noise from music. Nothing is perfect(even vinyl), and some really good LPs did not benefit from the noise reduction. However, fo... | |
| Living with popping and crackling Surface noise is a fact of life for vinyl. In the last decade before consumer digital media became available many kinds of hardware were developed to address the issue: dynamic noise filters (Carver Autocorrellator) pop and click eliminators (actu... | |
| Best tracks to "show off" your system Different systems excel in different kinds of music, so there is no "right answer" to this question.My system, with three elaborate subwoofer systems reproduces loud organ and chorus music in a way that no little box can approach, but yet that lit... | |
| Crossover cap value? Theaudiotweak...Have you calculated the phase shift at 1500 Hz caused by a 6 dB high pass filter at 275 Hz? You ought to. You might also like to compare this with the phase shift of the speaker's 1500 Hz crossover at this frequency. | |
| Crossover cap value? Since your objective is just to get the LF signal out of the HF amp, a 6 dB filter set well BELOW the driver crossover frequency would be best. Such a filter will be "out of the picture" at the break frequency of the speaker system's built-in cros... | |
| Wiring a Center Channel Yes, you will get a difference signal, and if you have inverted one stereo channel signal, this difference signal is indeed the common mode component of the stereo signals and is what you want to drive the center speaker. Of course, you must conne... |
