Tubes for Top, SS for Bottom--Good Idea?

I prefer the use of tube on top and ss on the bottom. No question ss produces a tighter, deeper bottom end. Tubes on the other hand are famous for fabulous mids and sweet highs. The secret is balance between the two. It is possible to find two amps with the same output but you'll have to be a lucky so n so to do it. You might find an amp or amps with level controls. Hopfully you'll like the sound of the amps or use a high quality crossover like a Bryston 10B (about $500. on the used market) with crossover settings and level controls. GOOD LUCK!

Yes, it can be a great way to combine the best of both worlds. I had done it for 4 years using Counterpoint equip, Solid-2 on the bottom, NP400 on the top (Hybrid). You need to be very careful when using 2 different amps because they may have different Gains and Power curves. Ie. How much power does it supply for the same amount of "volume control level". If the amp on top has a higher gain, you will have an extremely bright top end and no bass. Of course, vice versa for the other way around.

I am sorry - I do not get the question. You own all the equipment - why not hook it up both ways and try it for yourself??? Trust your ears, not others opinions.

No, that's the problem. I don't own all the equipment. I do not have an active crossover that will equalize the Dyna gain with that of the Perreaux. A good quality cross over costs about five hundred dollars. The other option is just to buy a good tube preamp and be satified with running the Perreaux alone.

Don't know if my experience helps, but here it is. I ran for the past two years with a pair of LA Audio monoblocs powering the high end with a Bryston 3B for the bottom. (The LA Audios are from a Danish company currently called Audio Design, my amps were ancestors of their current P3 amplifier.) This setup created such an amazing sense of presence, particularly with large orchestral and choral works, that I am afraid I am going to have great difficulty matching it. My current problem is that one of the KT88's blew up and that caused me to discover that there are serious maintenance needs for both amps. I am currently trying to sort that out. Meanwhile I tried using a Mark Levinson 332 in their place and the sound, while extremely clear and crisp, had no life to it. I can only guess that the magic I experienced was due to the warmth of tube sound. Just personal opinion, hope it is of some interest.
