High end Class D amps?

Ha! Photos or it didn’t happen.

Really more digs? You are the pits Ralph.

None of the 750 Sport as yet all it’s in bits in my workshop, but here are two shots of my Desmo 900 Super Sport I also restored slightly modded, and sold 10 years ago.

As for Moto Guzzi, they’re ok, had one of them also, a 1000 sport, same as this but black

nice looking built like a tank, but they ride like a tractor with their odd vibration, not being naturally balanced. The Ducati’s are superior in all departments that matter to a rider.

The rogue sphinx is a nicely designed class D/tube hybrid integrated. A very tastefully done design and no nonsense looks. The top of the line Marantz integrated is of a class D design. Not certain but I think it’s the PM 10. Also, the well reviewed Ruby integrated by Marants, designed by the late Ken ishiwata, you guessed it, class D.

Really more digs?

Ducatis like the 900 you had look fabulous; there's a few of those here in town. Apparently every single one of them emerged from boxes, and as you pointed out, your 750 Sport (also a fabulous looking bit of Italian dreamwork) is in boxes as I write this. That's where most of them are.


OTOH most of the older Laverdas you see in town have been in service (not boxes) since they were built (to be clear, there aren't nearly so many around). Ducati certainly is one of the few to make the Desmo drive work, but if its about riding across the country (here in the US that can be 1000s of miles) I'd prefer to do it on a Laverda even though some of their parts are harder to find (they vibrate more too), simply because it will hold together (I had both the 750SF2 and a Jarama 1000 triple). Ducatis and Moto Guzzi as you know share the same top end angles between their cylinders so vibration harmonically cancels; i.e. 'naturally balanced'.

 'naturally balanced'.

This statement is not correct!
And as far as Laverda's go your lucky to keep your fillings in your teeth after a ride.

Moto Guzzi's  feel very similar to the BMW horizontal flat twin vibrations, both are no-where near as smooth as he V Twin Ducati.

This statement is not correct either. Ducati's V-twins are perfect balanced because of the counter weighting that can be done (my mistake saying they were "naturally balanced")

Ducati:
The first thing is that Ducati V twins have or 90 degrees. This uniquely makes it possible to balance a 90-degree twin with counterweights of 100 percent of one piston's shaking force.

Moto Guzzi: 
"There are two aspects to our Moto Guzzi engines. One is that they are "fairly" vibration free compare to some other twins (like HD and old British twins) but "they still have secondary vibrations". But that is also separate from the side to side torqueing vibration of the motor that is more noticeable when you get on or off the gas but is always there." "Guzzi parts are not well balanced and the transverse layout also contributes...the late, great Gordon Jennings felt that transverse engines seem to vibrate more.."
