Has Anyone Uesed A PrimaLuna Amp With Harbeth Speaker's
@clarinetmonster2 I was quite surprised by the unqualified warranty claim. How many Rogues are sold vs PrimaLuna?I've been involved with tube amplifiers since the 1950's. PrimaLuna are built as well as any and far better than most. Solder work is ... 
re capping
The Truth is available from the manufacturer.Sometimes the Truth is optimistic and sometimes not.Life is predicted based on science and math, but can vary widely due to variation in sub contractor supplied materials.We once replaced 7 million 85°C... 
Who thinks $5K speaker cable really better than generic 14AWG cable?
Silver conducts 5% better than copper.R has the LEAST effect of LRC.Same geometry, same sound.Silver is Audio Jewelry. 
re capping
Electrolytic caps kept fully charged will function perfectly well and not degrade!Nope. There are multiple mechanism for electrolytic capacitors to degrade. We once replaced 7 million of them.The only way to properly test caps is to pull them all ...

Just look at these Stereophile measurements: https://www.stereophile.com/content/primaluna-dialogue-premium-power-amplifier-measurements it has a pretty bad load dependent frequency response.For those who don't read the article, the response is o... 
It's Simple
@kijanki I’m not going to correct all your errors, but this the level math:Assuming 0.02Ω in each cable lead [12’ of Belden 1311A or almost any equivalent gauge cable] with a 1V drive at the amplifier terminal:4Ω: 4 / (2 x 0.02) = 0.990V across th...

@nonoise even though 16 gauge is sufficient for cable lengths up to 36 feet, if your dealing with a 6 ohm speaker as opposed to a 8 ohm speaker, go for 14 gauge.Speakers are rarely an even 8Ω or any Ω for that matter. For example, a KEF LS50, nomi...

@nonoise ...every chart I looked at said...You'll never know until you try something...the manual just won't cut it.Color me confused 
Who thinks $5K speaker cable really better than generic 14AWG cable?
@johnluse As Abe Lincoln said, "50% of everything on the Internet is wrong"If one changes length, LRC increase.If one increases gauge L increases, R decreases and C will depend on the dielectric and spacing.So by changing length or gauge, you have... 
Curious How These Nordost Speaker Cables Do What They Do
@ethiessen1 @jmcgrogan2 +1, squared.1² = 1. Sorry, couldn't resist, but it illustrates some of the noise here that does not say anything.Systems with no onboard tone controls in my experience, have seemed to be more responsive to cable changes tha... 
It's Simple
@yping such as IMD, etcDistortions like TH, IM, TIM are active components faults.There are numerous other cable properties: Proximity Effect, Skin Effect, Purity, Metal, Plating, Insulation Dielectric, Fatigue, etc. All these properties have an ef... 
Curious How These Nordost Speaker Cables Do What They Do
@williewonka sorry you thought my post bombastic :-$ perhaps I get a bit carried away when fundamental laws are ignored. the current (i.e. energy), or maybe even the voltage, in the neutral (i.e. minus) conductor cannot possibly be the same as the... 
Who thinks $5K speaker cable really better than generic 14AWG cable?
There are definitely instruments that can measure.I posted this earlier for @shadorne An appropriate plain cable or wire is not going to change amplitude or phase in any meaningful way.This link shows Phase and Impedance for 3 speaker wires:Bob Ca... 
It's Simple
@shadorne I’m sorry if I’m not making my self clear.Seriously, please explain how one judges "faithful to the recorded music." I am truly interested because countless engineers have busted their asses for more than a century to bring playback ever...
