Hi Zia and Thimios,

Thank you both for your contributions......
Most of my power wires are twisted, but not that tightly. The mains wire is quite tight however, but you cannot see it and the wires are covered with heatshrink.
The signal paths are connected to power earth via a 10R resistor; and the IEC and power earth are connected to the one stud at the rear right. The pcb ground is connected to the power ground on the centre of the pcb with back to back diodes; that is, no galvanic connection to the chassis, but protected with high current smd diodes.
This approach works extremely well. The SAKSA, and the Maya in fact with same earthing, are utterly silent idling; you cannot hear anything on the speaker if with your ear inside the cone. Earthing is a black art; I have arrived at this after years of stuffing around!

Hugh

That previous pic of the Saksa Hugh posted was for a mate of mine, I fitted the supplied attenuator and have been running for around 10 or 12 hours now in my system. Just wanted to congratulate Hugh of a fine amp, It's a cracker! nicely blending of what I find nice in the subjective aspects of SS and tubes. At times I could have easily thought I was listening to my triode strapped EL34 amp, especially with acoustic material. These will be partnered with my friends Aurum Cantus M103's after I hand it over to him.

Hi Pathway,

Thank you for the post; you got the amp up quickly and this weekend you deliver the amp to its new owner!

I hope you remain in our forum; i enjoyed your careful observations and I thought you were balanced in an area we know is opinionated!

Hugh

Hay Hugh, the Saksa will be with me for a bit more, my friend needs a few more bits for his setup. Though had a listen to the Saksa in my setup on the weekend and is very happy with the amps performance.

Thanks for the post, PW!
I wish you all the best with the source switching, it's not a trivial issue and has to be done really well to avoid noise.
I was incredibly pleased with your view that the SAKSA compares more than well with your lovely PP Triode amp, which I'm sure would sound fantastic.
You know, that was EXACTLY what I was trying to achieve; a tube sound from SS, with resolution, depth of image, powerful dynamic, harmonic tonality, and low noise.

You might consider the next SAKSA for yourself? Or perhaps a Maya?

Hugh

Is a nice blend of attributes of both, Hugh. The valve amp has more weight to it but lacks the resolution, clarity and grip of the saksa. For myself mids is where there are similarities mostly, vocals can sound similar to my ears. I guess mids are an important part being where most of the music is. Very enjoyable to listen to, I'll be with valves for the time being but maybe one day I will be in a budgetary position to pick one up myself, but then the Maya would be a temptation at that point. Time will tell. Cheers

Aha, Ian, I await your keen interest in the Maya in time......!!

Thank you for your post, and your thoughts, much appreciated.

Ciao,
