| Power amplifier longevity… thoughts? @devinplombier I appreciate the advice. Pass Labs uses a current limiting supply. I don't have one of those and they are pricy. I might try using an ac variac with a series of increased wattage incandescent bulbs in series with the line cord. | |
| Power amplifier longevity… thoughts? I'm new here and I don't want to do anything inappropriate but awhile back I posted that I have a new Pass Labs X5 power amp that has never been installed (boxed up for over 20 years). I asked for suggestions about powering this unit up after bein... | |
| End of a long quest to vanquish sibilance. Concrete, being a denser and stiffer material than wood, tends to have a higher resonant frequency and may be a reason for increased high end. | |
| End of a long quest to vanquish sibilance. Is it possible then that since it's not height, it could be the increased rigidity of the speaker vibrating the tweeters? | |
| End of a long quest to vanquish sibilance. I’m an old professional audio guy who spent over 25 years fighting sibilance in the analog magnetic tape era. I must say this post brings back many memories dealing with high frequency distortion. Eliminating sibilance was probably the hardest thi... | |
| JBL's Marketing Blunder.. "As for JBL is junk" I'll bet a lot of older content you are listening to was mixed down with 4311 control room monitors. | |
| Have you noticed as your system improves? While reading these posts I wanted to mention that I believe speakers have improved over the years and don't need to be driven so hard to get good results. aewarren beat me to the point. | |
| Which has a greater influence on sound quality, the amp or the preamp? Both can, and do affect sound quality. Every component and interconnection in the chain affects the quality. Depending on your source you don't always need a preamp in the system. | |
| Suggestions for testing a never installed, 20-year boxed amp. I don't have any decent speakers for this amp. If this amp tests ok I will have a tough decision to make. Do I keep it and build a system around it or get rid of it? Either way, I need to know if it works. | |
| Suggestions for testing a never installed, 20-year boxed amp. OK - I took your advice and contacted Pass Labs. Someone actually answered the phone and referred me to Kent who was very helpful. His concern was with the capacitors as some of you mentioned. Kent recommended a "current limited power up" using a ... | |
| Suggestions for testing a never installed, 20-year boxed amp. All good ideas. I'll try to contact Pass Labs Monday before doing anything. I already have a lightbulb current limiter setup, a variac, and some 250W 8ohm resistors. My acquisition of this amp is a long story. The company I worked for, at the tim... | |
