Many balanced leads available in the HI-FI World are not – one earth pin is either not connected internally or bridged in a pseudo-balanced way. Glue-up plug barrel – Hey Presto!
I have had many Croft Series 7 hybrids through my hands over the years and they do not run hot. They run warm as owners will attest. Yet, when being technically measured by Stereophile, they managed to get the Croft Integrated amplifier to run very hot and then considered it a fair report.
My suspicion is that a music signal is less stressing to some amp topologies than the ‘steady-state one third power signal into a simulated load’ used by the technical reviewers.
So a topology of amp which tolerates this will have a technical advantage over one that does not. Of course, if you like to listen to a single note all the time….
As mentioned I have loaned out all my Vertex gear to a customer for a 1 week trial period.
A pair of large 3 way speakers with 12 inch bass drivers are out on demonstration to another customer who has concluded that they need to be played too loudly to be at their best in his set-up. In my room, with Vertex installed and the same Croft amplification, there is no such problem and they play excellently at low volumes – interesting…
One of the first things that strikes you about the Vertex range is that it is fantastic at controlling boom levels * – my 10.5 ft wide demo room with suspended floor can now work with unfeasibly large speakers even with 15 inch bass drivers thanks to Vertex.
I have loaned out all my Vertex gear to a customer for a 1 week trial period and the boom is back and unbearable forcing me to change back to mini-monitors!
I remember this being a big issue before discovering this brand.
(* Actually, the first thing that strikes most people trying the Vertex gear is the better image placement/separation and lower noise floor. But each system is different and my main issue had been boom levels and the need to demonstrate various speakers of all sizes. )
