Int. Amp Recommendation

Thanks for the replies so far.
As for tubes, I already have a Consonance M99 Integrated with remote and that's enough for the moment.

What are the main differences between the Musical Fidelity X-150 and A300 ?

One more question, do you think that these int. amp that I've mentioned are allround better than the Rotel separates I initially posted ?

The Portlal Panache. I understand these are tested with Apogee's for quality control. That's a speaker most separate power amps won't handle.

If you dont mind my asking, what exactly do you dislike about the sound of your lousy separates system ? I mean, besides the fact you think they are lousy and take up too much space. In what way is this system failing your Jbls? I ask because you seem to know what your Jbls have in store given the right sort of amplification.

Timf,

My amp is a 5 channel AV amp and I have three channels that I've never used and I know that it's not among Carver's good amp list, I know I can get better sound with a new amp

My pre is not really a pre, it's a Denon receiver and although it has something which is called Pure Direect mode which shuts down the video and digital circuits I also think I can do better with a dedicated 2 channel pre or an intagrated in this case.

I really think that most any of the options I mentioned in my initial post will be a substantial improvement over the Carver/Denon combo, the speakers are keepers and when I do upgrade they will stay for a second system.

Plese let me know about the differences of the two MF's I mention.

Thanks.

My gear is now in the living room and it does sound much better than the previous one, specially in the imaging department.
