| A listening test of two power amps Normalizing should be done to peak amplitude, not RMS. Both of your files have a peak amplitude that is clipped at between 1’08” and 1’09”. I generally normalize to -1.0 dB of peak. I used values in your original samples to come up with the value... | |
| A listening test of two power amps In the samples I sent to you, the waveforms were normalized to -3.0 dB, then the zoomed portion was normalized to -0.3 dB. In the zoomed section, the noise on the quiet part of the j-piano-zoom was very similar on both the left and right channel.... | |
| A listening test of two power amps Just read your post about distortion on the j and y piano files. I think you may have something else going on. Looking at the wave form of the j and p files, there is almost no ripple in the quiet parts on either file. Certainly not enough to be a... | |
| A listening test of two power amps Listened to all nine as originally provided, and with a modification (more on that later). In general across the 3 different versions of each I liked j the most, y second, and p the least. Differences are slight. I like the attack on j and y the ... | |
| A listening test of two power amps @surdo Finally got to due a little more compare of the e & t files. My first try was at a lower volume than I think should be used for comparison. First pass at that low volume, file e was much better than t, but on replay, t was closer to e... | |
| A listening test of two power amps @erik_squires "1. Match level by multimeter instead of SPL. Get a 60 Hz signal and check the output on either speaker. You can get really accurate this way." I am a little ambivalent about using 60Hz sine and voltage to verify output level balanc... | |
| A listening test of two power amps Haven’t listened to the files yet, but hope to later today. I find your wiring configuration of the Sunfire amp confusing. To my understanding, current drive would have the most effect on the lower frequencies. The tweeters should not need for mu... | |
| The real truth about recordings Read the article, and wanted to add some thoughts in a slightly different vein. All music is an emotional and energy experience. That is the main point. Whether it is a live performance, a studio performance, or a recording of one of those perform... | |
| Sharing a subwoofer between a Stereo and HT combination. Thanks to all replies. It looks like there are 3 solutions, but with some restrictions. 1. Parasound Halo P6 preamp, and the Parasound Hint6 both have 2 sub line level or LFE bypass inputs as well as the HT bypass inputs. Will check them out at t... | |
| Sharing a subwoofer between a Stereo and HT combination. @soix First, disregard option 1 of adding a stereo amp — you don’t wanna leave the AVR’s preamp section in the stereo pathway so either an integrated or separates is the way to go. You should share what sound characteristics are most important t... | |
| Anyone listen to Music on a FM tuner anymore? I’m one of those that listen to HD radio in my office set up. Found an older Sony HD tuner that is what got me into paying attention to the rest of my stereo environment. Lucky to have a number of HD stations in the Philadelphia area that are goo... | |

| Will audio gear be ok in unheated house As others have said, capacitors may be at risk if frozen. If any components have printed circuit boards, there is also some danger from solder spiders if the humidity and electrostatic charge is just right. Not an issue with point to point wiring.... | |
| Are you on or off? What say you? Standing very close to the merry go round. First step on was back in the 80’s with a Luxman c120 preamp and m120 amp, added DCM Timewindows, and a Mitsubishi LT1 turntable. Great stuff at the time and kept me happy for a long time. Old now (>70... | |
| Can a tube amp be damaged by a speaker switch? I am a bit confused. All of the comments are good, and are good suggestions for what you are choosing for a solution, but I think the approach is all wrong. What Marantz receiver are you using? Does it not have Pre outs? What Leben amp? Is it an... |
