Shoot-out Klyne 7xp3.5 vs IO Signature

Thank-you, Syntax, for your observations.

Lewm,

I have certainly had the Futterman in the line-up. Funny, even with this 40year old + piece of equipment you can see very clearly in to the illusion. It is uncanny. The Futterman is grainy but suits the quads well. I have never had an explosion or failure either so I have not experienced the pyrotechnics some speak of with this amp.

It's voltage regulation and bias seem to hunt around a bit, but this is more a function of the tubes and their reflection back to the circuit. I really like that amp. I used to own acoustat model threes and acoustat X's (sorry I sold them, warts and all). I have heard regularly, big dyna audios, revels and audio physic and for all the limitations of the quads, not ready to give them up yet. I like the Verity line-up and might consider it in future. Never, heard Sound lab (would love to!) I know I would love them.

One combo I have not tried yet is the Klyne with the Berning.. now talk about punchy bass!

Regards,

Nkj, You might get significant improvement in the sound from the Futterman H3 by bypassing the electrolytic output caps using high quality film caps. If you have an original H3, an even better thing to do would be to get rid of the old lytics and replace them with some state-of-the-art low-ESR types that are now available, like Panasonic TS-EDs or FCs (depending upon the voltage rating needed) THEN bypass those new lytics with some good film caps. I predict this will ameliorate the grainy quality you hear but will also have unanticipated benefits across the board.

Hi Lewm,

We are getting side tracked here on this thread! I already have solen film bypasses on the output electrolytics. The value of the output caps is in excess of 600 uf if memory serves... I always planned to get a pair of these:

Never got around to ordering some.. the form factor is larger so I would have to be creative to mount them without modifying the chassis. All the caps in my amp have been changed from the awful Goodalls to modern films for reliability.

Cheers,
