Accuphase DP-90/DC-91 combo outdated?
I just want to let you know that inserting a Purist Audio Design Dominus AES/EBU between my Accuphase DP-90/DC-91 results in a more vinyl like sound, that means more PRAT, dynamics and a blacker blackground. Treble sounds more silky. Can anyone te... 
Boulder amps v,s Levinson amps
Hi, I wonder if Madrigal is capable to design an amplifier that is as good as a Boulder. Does anyone know how the Boulder sounds compared with FM Acoustics? 
Tchaikovsky symphony 5 favorite recording
Hi, although this is an important issue, it is off topic imho (belongs to the "music" not the "tech talk" forum). 
Best 5 engineered rock albums?
Dear Tvad, this thread is about amps and preamps, not engineering. I like to talk about music and sound engineering too, but the music or miscelaneous section will suit this subject better. 
Best 5 engineered rock albums?
Hi, this is an off topic thread. 
Bose 901
I'm not a bose adept either. I was rather curious if there is some positive aspect regarding the 901's sound. To me musicality is more important than let's say accuracy or a good pin point imaging (where is pin point imaging good for by the way: a... 
Bose 901
I started this thread after reading a review about the 901's from an audiophile. He was very enthousiastic about the speakers, although he also has heard many other high end speakers from very respected manufacturers. He said nothing compares to t... 
accidental power down....any damage???
Why should the amp been damage by only turning the preamp off and on? Isn't that what we are doing after a listening session? It shouldn't also make a difference if the switching takes place with or without music. 
Slew rate and rise time
Sean, I think Herman is right: http://www.amplifier.cd/Tutorial/Slew_Rate/SlewRate.htm.But I also understand your analogy, Sean. Is slew rate analogous to a car's acceleration speed and rise time to the time a car needs to go from 0 to 90 mph? The... 
Slew rate and rise time
Thank you Sean for your descriptive analogy. I'll keep it also. You know, another issue for discussion is also what the relationship is between gain, volume and amount of power that an amp delivers. Let's say an amp is capable of delivering 200wpc... 
Slew rate and rise time
Thx for explanation Herman. 
Biamping Dunlavy SC-V
Hi folks, I just want to let you know that the problem has been solved. I asked Peter Thompsen from Acoustic Reality and he has been very kind to get into some analysis of the problem. Due to his suggestions it is now clear what the culprit of the... 
Biamping Dunlavy SC-V
Thanks both of you Sean and Tom. You have been tremendously helpful. You are very knowledgable Sean, you must have a technical background I suppose.Well, the Acoustic Reality has an 8 kOhm input impedance, which is low. An Accuphase representative... 
Biamping Dunlavy SC-V
Hi Sean, thx for the thorough explanation. I'm not a technician, but wouldn't a well designed loudspeaker system comprise drivers with the same impedance? Otherwise the system would not sounding balanced through out the frequency spectrum. But it ... 
Biamping Dunlavy SC-V
I started this thread because I did biamping before with four identical Acoustic Reality ICEpower amps (each with 500wpc), but when biamped there is a reinforcement of bass (some 3 dB or more) while the midrange/treble were a bit subdued and less ...
