PREAMP technology shift? - Class A/ balanced/ dual-mono/ zero feedback vs. op-amp preamps
you can always spend a bit fixing up the pro 10mc, refreshing its capacitors with newer higher spec ones (minimally...all the old electrolytics have to go)..and then look at changing the opamps in it to higher spec newer designs.this is the least ... 
Channel Imbalance at low volumes
It can be dried out off brand capacitors, dirty relays, dirty pots, dirty switches, and so on.the unit is from 1986, and was made in Taiwan with off brand capacitors.It’s old and it’s tired.It needs a cleaning, check out, new capacitors on many sp... 
How critical is Mosfet matching in power amp output stages?
Matching tends to count most when you edge toward high levels of output and the stressing through massive transients in a mixed harmonic, well, the micro distortions become macro and then you pop an output transistor or two.In the rest of the give... 
Are future improvements in Amp/PreAmps slowing to a crawl?
The problem is that the best you can experience, or record, is a subtle loss of transient function, so... likened to a master tape copy.. slightly darker, slightly duller, slightly slower. light recording has the same issues, or of a similar type ... 
Are future improvements in Amp/PreAmps slowing to a crawl?
To continue:As long as we seek, this will continue, without abatement.Any form of of screeching, hating, throwing insults or rocks about will change nothing. This sort of written communication is about reflection, not transference.As long as the g... 
Are future improvements in Amp/PreAmps slowing to a crawl?
If you find outstanding (better than anything else on the market or ever mass produced) measured performance to be a meaningless achievement then how do you propose to measure what you find important? I would put it to you and everyone here that ... 
$100,000 line stage
Do you really think the reviewer bought the review unit at 50% off retail? Mark-ups on some of these uber priced gear can be unbelievable. When I was importing Kondo gear (Audio Note Japan) and selling Ongaku amps they had a retail of $89,000.... 
Teo Game-Changer IC's - get on the bus!
you're gonna regret it..... :p 
Why don't amplifier Companies use high end fuses?
Under transient loading and a traditional power supply or rectifiers, caps and transformers..the fuse is definitely in the signal path.And it carries import due to the fact that the ear/brain derives 100% of what it hears, via 10% of the signal --... 
Why don't amplifier Companies use high end fuses?
If it is just a piece of wire, then replace the emitter resistors in an amplifier with pigtail fuses, or wire lead micro fuses. ( I used sockets, so I could change the values and types)Go ahead, try it.Sounds like crap on a level that is near impo... 
Systemdek 11X Issues
You'll have to do a bit of research. As the sytemdeks age, they are running into motor and motor mounting problems. Common enough that you should be able to find some data on dealing with those exact problems. 
Design a $60,000 Speaker - Start here
One can go entirely active with speakers, yes, but the speakers will still sound notably better if the drivers have passive zobel networks. 
Design a $60,000 Speaker - Start here
The acoustics and improvement of bass in consumer listening rooms is very well understood,...... On my life, I fundamentally disagree. (in a casual friendly way... but if pushed...) I’m talking about how the ’fix’ of the rooms is, in my direct ex... 
Are future improvements in Amp/PreAmps slowing to a crawl?
'The end of science' bit in the title is mostly journalistic license in designing a hook for the article.Nelson speaks on some of this via: The other fundamental thing—number 2—is that I am centrally aware that all this is just entertainment, min... 
Are future improvements in Amp/PreAmps slowing to a crawl?
Hey Ralph,the liquid metal cable is all about re-writing the ground that electricity walks on. As fundamental a mental shift as can ever be. From the molecular and quantum levels, on up. Hardcore and real.However, it’s a difficult thing for most p...
