| The Best Audiophile Earphones headphones and Amp One thing to consider- the 4-wire system sounds immediately better than the 3-wire system (1/4" stereo connector)- its not subtle.If you want the best then the 4-wire system is mandatory. | |
| Is there an average life span for a preamp? Kijanki, there may be something I'm missing but I would not expect much change to the output impedance with most amplifiers or preamps on account of the condition of the filter caps. In every case I have seen if the caps are ailing, replacement un... | |
| Is there an average life span for a preamp? Kijanki, that sounds about right to me. However as a side hobby I like to restore vintage analog synthesizers. Its pretty well universally accepted amongst those who do such work that the filter caps in the power supply should be among the first t... | |
| Is there an average life span for a preamp? Filter capacitors will hold up better if they continue to get used on a regular basis. However they will still degrade. Any piece that is over 20 years old should be considered suspect. It may well still work, but that is not the same as saying th... | |
| Why are modern arms so ugly? I remember the old Zentih Cobra looked pretty nice. I would never let any of my LPs anywhere near one though. I leave that to an arm that is unperturbed by any track recorded in vinyl. Perception is a funny thing and it is long proven that there i... | |
| Is there an average life span for a preamp? The main limitation is the life of the filter capacitors in the power supply. These days the half life of them is about 20 years (IOW- in 20 years half of them will have failed).Of course many units will run longer than that but its a safe bet tha... | |
| What will raising the Va of atransformers provide? The intent with this Q & A is to [hopefully] make sure I'm not leaving anything on the table when it comes to getting the fullest reproduction available.Well heck, you could try out some tubes in that system :) | |
| Preamp for Pass The input impedance of the Pass can be challenging for many tube preamps, including the ARC, which was covered in another thread.This usually has to do with the output coupling capacitor of the preamp. A few tube preamps (a very few) are direct-co... | |
| Amp and Preamp for JM Lab Alto Utopias We also get 100% humidity. We have torrential rains for months at a time, and homes accumulate mold and mildew. It's really a dreadful climate those times of the year.Sounds a lot like Minnesota! | |
| Cartridge Loading and Compliance Laws Depends on the washer... a nylon washer should probably be avoided- the coupling between the cartridge and arm should be as tight as possible, and nylon will squish. | |
| 4 ohm or 8 ohm tap Yes but only slightly- it will be inconsequential. | |
| Why 24/7 warm-up period on amps? No, a power supply cord is in SERIES with the ENTIRE ROMEX lead and all the way back to the power station. An insignificant voltage drop and even less so if the lead is equal to the ROMEX in AC resistance. So if you use a 12AWG cord you're NOT goi... | |
| HELP-woofer moves alot when playing lps Fleib, there is another thread on this subject that is current as of this writing, that does address this issue also:http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1315713166&&&/Cartridge-Loading-and-Compliance-LawsRead the posts by... | |
| Why 24/7 warm-up period on amps? Paperw8, the amp I mentioned in my example draws 500W from the wall at full power.If you dig around on this forum, you will find that the idea that the stereo sounds better late at night is a fairly common experience. IOW you are right that other ... | |
| HELP-woofer moves alot when playing lps Dan_ed, At the very least, yes, though I don't understand what you are getting at at all. I feel like you are misunderstanding something though as there appears to be animosity on your part.So maybe I have not been clear enough:Woofer pumping is n... |
