Solid states more accurate than tubes?
isn’t there only one true fidelity No. We all hear differently. We all remember differently.Different aspects of reproduced sound are preferred.

Systems are about mating components.Look at these Proac impedance graphs at Stereophile:https://www.stereophile.com/images/archivesart/808P28fig1.jpghttps://www.stereophile.com/images/archivesart/610PD2fig1.jpghttps://www.stereophile.com/images/32... 
PRIMA LUNA AMPLIFIERS
There is a switch on the side for low and high output tubes. EL34 being low output, and KT120, KT150 etc. are considered high output. The switch is for EL34 or KT-88 bias. The KT-120 & KT-150 are a whole different tube than the KT-88. The 1...

ksubrama: The 150 draws considerably more heater current than the EL34. Can the amp supply it? The operating point will change which will change the distortion considerably.Do you have the tools / know how to adjust the amplifier to optimize for...

How to accurately gauge speaker sensitivity to match with tube amp?
@djones51A square wave is an infinite series of odd harmonics above the fundamental. When an amp clips, the waveform stops at the power supply limit and creates an odd multiple series of the clipped fundamental. Below is an abreviated list of 200H...

Another untruth from Mr Kait. Like herpes, there is no cure.

I and others are flattered Mr Kait follows and posts, caring not to diminish our belief in his inanity.

@atmasphere +1An amplifier, cables and speakers form a system in which they interact.Anyone who claims one thing in particular is a panacea for all ills is prevaricating.To wit, from MBL Noble Line N11 line preamplifier @ https://www.stereophile....

driver tubes ... have more influence on the sound than power tubes Nonsense. Tubes are like fine wine. They vary bottle to bottle and with temperature, age and side dishes [system and programme].@hilde45 - IMO, there are better options than a sh...

Smaller mains and a pair of subs:Relieving the amp of the necessity of driving the low end roller coaster effectively doubles its power, allowing less efficient unported mains. [I've never heard ported low end I liked].Getting smaller mains up on ...
