”Highly recommended!”

Nome: Guido Brivio

Professione: Docente universitario.

E’ molto raro, come è noto, che uno specialista di Hi fi – e in genere di qualunque servizio – lasci completamente soddisfatti e non mostri pecche. Ma questo è il caso. Adrian Parsons di Audioflair ha mostrato eccezionale competenza, pazienza  e raffinatezza nel mettere a punto un impianto hi end di inaudita – è il caso di dirlo – qualità, sapendo ascoltare le mie esigenze e trovando la soluzione ideale. Il tutto, incredibile a dirsi, a un costo davvero ragionevole per la qualità dei componenti, dimostrando un’onestà, correttezza e trasparenza che sembrano non avere nulla a che fare con il mondo del mero commercio ma piuttosto con quello dell’amicizia. Highly recommended!

Pink Triangle PT00 – 650 Euros. Now sold.

Serviced by Arthur K. at Funk Firm with Funk Firm Achromat and acrylic armboard.

This was serviced by Arthur and then traded-in soon after.
There are 3 drive belts and 3 hinge Lids.
A Funk Firm mat and perspex armboard plus the original armboard.
No lid.
Can supply and fit with excellent Gold Note B5.1 arm for extra £730.
(B5.1 arm in pictures is mine, but I could supply a new, unopened one.)

Excellent 3D depth and emotional involvement.

It has the bigger Pink Triangle power supply tested and working well.

PT00 fully tested 650 Euros without arm.

 

 

 

Fake Balanced Leads

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!

Reflecting back on Stereophile’s Croft Integrated review

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 make the Croft Integrated amplifier run ‘very hot’ and 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….

This is one way in which you can achieve the contradictory situation where the reviewers rave about the amp, as occurred with the Croft Integrated, while the technician finds fault.
You can bet the Integrated did not run hot at the reviewer’s houses (before and after the measurements were taken) when sounding so musical.
As is often the case their testing is not what they think it is. If it ran hot on test bench they were overloading it in some way and inducing distortion.
The trouble with this kind of ‘science’ is that readers of such reviews tend to feel obliged to bow to the measurement facts unquestioningly.
Many years ago Glenn Croft said, ‘When you know what you’re measuring, measure it!’
It seems the measurements were taken from the Tape Out rather than the speaker outputs which would have loaded-down the amplifier’s output and induced the 6db roll-off.
Let’s not forget that Total Harmonic Distortion is also overstated as many Jap amps had vanishingly low figures such as 0.01% distortion and sounded rather thin and unengaging in reviews. In the meantime most speakers distort by about 33%…
If you prefer a more objective perspective regarding magazine technical measurements, Steve Elford of Vertex AQ cites that:
“Fourier transform theorem or FFT software is the wrong way to measure because it’s in the frequency domain and is an iterative process over time so you only see the presence of constant sine waves. By analysing the signal in the time domain, only then can you see the tracking error.”

10/10/15 Further thoughts on Vertex.

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…

Thoughts on Vertex equipment.

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. )
