Hybrid vs. Straight Tubes

I am serioulsy considering the purchase of a Jolida Hybrid Amplifier, most likely an integrated amp (tube-pre section with solid state power). The amp will be used to drive my Monitor Audio RS6s.

I am after tube sound and coloration.

The advantage of the hybrid amp is the added power at a reasonable cost.

My question is, will I be trading off the tube qualities for added power? And, is the added power even needed to drive my speakers?

Which would be preferable a 40 watt tube amp, or a 100 watt hybrid?

PS: For more details regarding my system, please see my post in virtual systems.

Thanks!

The really expensive part of a tube amp is the output stage, if you use tubes in driver stage and mosfet output stage you can get a lot of the tube sound. I used an amp like this at one time and it worked well.

If yoo really want to find out why tubes have a very dedicate bunch of fanatics. To hear what makes a tube amp really magical, it is imperative that you have an all tube power output stage . Not a shadow of doubt period about it.

The same can be said for changing the input tubes in tube amps as well. Changing cables will change the sound too, so I'm not really sure what the point of that statement is.

But I do know that I used to use tube/MOSFET hybrid amps and now I'm back to all tube designs. This is not to say that I'm not open to trying other designs in the future.
