Thinking of buying a solid state amp

The new ModWright kWA 150 is a killer for the money. It can be run in stereo or bridged into mono. A solid state amp that will definitely appeal to a tube lover. Dan Wright is great to deal with.

Guidocorona, thanks for the info on class-D. I haven't followed class-D development that closely since introduction, my impression from the short ownership with class-D was just like what you described, lack of harmonic texture and delicacy. I have heard lots of good words about Rowland 3XX amps, but I wonder how they compared to Pass X350.5 which can be had for much less.

Moemoney, I know exactly what you meant. I have always owned tube amps and buy SS from time to time to see how things have improved over time. but as recent as a couple years ago, I still found BAT to outgun $20K+ SS amp in midrange and up. I might very well take the same route as you do, buy an inexpensive SS to use in hot days.

Luxman are priced different in asia and worth a look. I used to own Rowland 312 and x350.5. Knowing your taste, I doubt you'll like the 312.

I will miss a good listening buddy.

GLI, what sonic differences did you perceive between JRDG 312 and Pass X350.5?

Thanks, Guido

'd' just like any other topology has good and bad examples.
PF correction is used to help present a more resistive load to the power company. Large factories are penalized by the electric company when there PF drops below 0.9 or so, which is a moderate phase angle. I have measured my 40watt fluorescent tube at 0.8, when warmed up.

If such a circuit is presented B4 the amplifier, the amp's power supply need not be any different than without the PF correction circuit.

I have not yet measured my 'd' amp's PF, but will have data within a week. I suspect the PF to change as a function of load on the amp, but not sure in which direction it will go. I will be able to measure total draw, as well.

The Spectron amp is an animal. A very large number of smaller caps on each rail is featured in the power supply for lower resistance. Quite an amp, at least on paper. I'd like to hear it on my Maggies.
