Backbraking experience: CA9

[Daniel L.]

What about the Crest Pro Series? Half the weight of the CA series amps. Personally, I've never heard either amp, but it seems worth comparing.

I believe the magic of the CA series is the result of the power amp design and it's massive reserves, which, is the reason for the weight, so I don't think the Pro series would be the same.

OMG...same weight as the db 750, but headroom and tone for days.

I sincerely hope you're not questionnig the headroom available with a DB750. Its 750 watts into a 4 ohm load is ridiculously conservative (IMO) and has headroom virtually beyond anything I've ever had a need for or could really imagine.

This is of course IMHO, and if I've misunderstood your post then my shoe is certainly tasting good right about now

The reason for the weight is a very large transformer and the chassis to support it. The reserves is in the caps. IMHO, the "magic" of the CA series is in the gain. I schlepped mine around for 2 years before I figured it out.

But I thought that huge transformer was also a function of it's ability to source huge current (even at a given gain ratio), which is also a function of the reserve power... I think the caps are just for the transients, but you gotta' back that up with strong current sourcing abilities to keep it going, and I thought that was all about the transformer... no?

The wind ratio is what governs the voltage staging, but the size of the wire is what governs the current sourcing capabilities... at least as far as I know...

+1 for the QSC PLX1804

I run a SansAmp PSA-1 into a single channel of my 1804 then into a 8 ohm Sunn 410H cab; it easily holds its own against 2 guitarists and I've never had to take the gain over 12 o'clock. Plus as everyone else has already said its so light.

Now to find a second 410H for the other channel... not easy in Australia.

Finaly I ended up with a QSC PLX 3002 and so far there is nothing to complain about.
I´ll be back with more input on this unit when I´ve tried it out more.

my crown XTi 2000 does fairly well in our oppressively hot and humid practice space. 17lbs isn't too bad for 2,000 watts bridged.

Yeah and more than likely there won't ever be.
Great amps!

Those are interesting amps and the price looks pretty good -- I wonder how they compare to the MacroTech's (or other good lead-sleds) tone-wise.
