Zen V4 and A75 listening with CCS-X-BOSOZ

[Alain Dupont]

Hi,

I had a meeting this afternoon with Francois Gagné he came home with his Zen V4

I had my A75 and a prototype CCS-X-BOSOZ ,

Wonderful afternoon, the CCS-X-BOSOZ dit the job well unbalanced
on the Zen V4 or balanced on the A75

The Zen V4 is such a great amplifier, we should do these meetings
more often.

It has been a privilege to listen to both amplifiers.

Thanks Nelson, the Zen V4 is realy a great Pass amplifier
so is the A75, the difference was subtle, even rethinking of some listenings ;
each amplifiers has its own signature, but overall the sound was great.
Even it was difficult to tell which sounded better, they gave us
marvelous sound, and great pleasure.

Two great amplifiers, and a fantastic afternoon.

Thanks for sharing. I liked all those amps, but then I
have been accused of being undiscriminating

[FrankDIY]

Alain does not want to admit it but his A75 was very musical, more musical then my Zen V4. The piano was amazing compared to the Zen. Maybe the Martin Logan are not the best match to see the quality of the Zen? Both were good performers with the music we listened.

Of course, we tried Frank Zappa...so Nelson can sleep in peace

Very nice afternoon!

Francois,

Thanks,

Nelson, we loved the session, and Zappa is great !

I have a question for you, I and looking at the Aleph 1.7 preamp
and found a 87LPC762 to replace the dead 87C752 from Philips
is it difficult to program these circuits both for volume control and selection of entries ?

Best regards.

Alain.

[FrankDIY]

Now I will be confused, an Aleph 2 or a A75??

Alain and Francois,

I also have Martin Logan Aerius i speakers. How did the Zen V4 do driving them? Was there enough umph out of the V4 to drive the Aerius i well?

We need Wayne to answer that question. I can design a
processor, but I haven't the faintest idea how to program one

kilowattski,

Yes I think there is enough ; but we didn't try the Zen V4 at high volumes
on the Aerius i . The listening gave very good results, but to my point of view the ML Aerius i need big amplifiers, like the A75. I would love to try a Aleph X with 80/100 watts. {I have two Aleph X Pcb's from HiFiZen ; but it's a future project, to try biamping the ML}

Nelson,

Well, thanks. It would be kind if you could ask Wayne about that.
I dont need details; but a little overview of the process could help me.

Best regards.

Tested alone with these speakers, I think you will like the sound but when compared with the A75, it sounded to me less musical (especially with the piano). Again, we did not tried many different type of music and one amplifier was balanced and the other one not so could it be the difference?? I don't know.

Alain? Opinion?
