| Is it too much to ask.... Power gives some idea, but it is pretty much useless specification without knowing how it was measured. My amp, for instance, has module rated at 200W/4ohm but only 55W according to FTC measurement (that requires 1 hour preheat). It is possible fo... | |
| Jeff Rowland Capri- looking for love. Nasaman, Jeff Rowland uses switching power supplies (including Capri) for low noise. He also uses switching power supply in his latest designs Model 625 and 725 that are class AB amps. He explains technical reasons here:http://jeffrowlandgroup.com... | |
| Hookup wire for tube amplifier? Of course 7N copper exists. It is even a subject of international conferences like this one:http://jp4.journaldephysique.org/index.php?option=com_article&access=standard&Itemid=129&url=/articles/jp4/abs/1995/07/jp4199505C747/jp4199505C... | |
| Office partitions as sound panels Mapman, I wonder if placing 2" panels on opposite walls works the same way as 4" panels on one wall? It should.Kr4, I have a lot of reverberation between tall walls (cathedral ceiling). It would be ideal to space panels away from the back wall but... | |
| Good entry into R2R Don't forget about layer to layer copying effect. My friend, who works for very large recording studio, said that they had to constantly rewind all tapes in storage to minimize this effect. | |
| Office partitions as sound panels I'm building twelve 4x8 panels using 2" rigid Johns Manville 817 panels:http://www.jm.com/insulation/performance_materials/products/ci9_800series_spin-glas.pdfLook at the table showing sound absorption coefficient at 125Hz for 1" and 2" thickness.... | |
| Petition: Stop the loudness wars The loudness war is where record labels turn the volume of a recording up to grab the listener’s attention upon first hearingThat's not the only reason for compression. Music is targeted for average inexpensive system (or boombox) that wouldn't be... | |
| No Balanced Circuitry Does it mean that the XLR output are not fully balanced....???"Fully balanced" is a term that applies to amplifier construction and not the input or output. Input can be balanced (in non fully balanced amp) by either Transformer or Instrumentation... | |
| How to ground a shielded interconnect You have to understand how the shield works. Interference can be capacitively or electromagnetically coupled. In first case it is straight forward draining interference to ground. In case of electromagnetic interference lower frequency coupling is... | |
| big screen - two channel system enough for dialog? It should reinforce center (improve imaging) for off center sitting position. | |
| I Take My Music Seriously Grand piano - I played only once because didn't like the feel. | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, Term "Scale" applies to all string instruments. Please read here: http://en.wikipedia.org/wiki/Scale_%28string_instruments%29Upright basses have 10" longer scale than bass guitar. It makes for much higher string tension* resulting in (a... | |
| Why do audiophiles shun feedback in amplifiers? Ralph, My previous speakers had smaller woofers and smaller cabinets but bass extension was 5Hz lower. Bass quality wise it is much better now with more natural attack and decay. It sounds more even, resonating less with the room (same amplifier).... | |
| Why does better power = better sound? Most "cheap" voltage regulators are less than 2.0% regulation like a LM340If I remember correctly LM340 has 0.01% Vout/V line regulation and 0.3% Vout/I of load regulation. Perhaps you had in mind output voltage tolerance that is indeed 2% in the ... | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, Upright bass has better "definition" related to fact that strings are, being long scale, at high tension. Sound of plucked string instrument can be defined by factors like Presence, Projection, Sustain, Separation and Tone. Upright bass... |
