Need help What monoblock power amps for bass?

Thanks a lot Atma.Your knowledge always helps a lot.I think Sinfonia was designed for bi-amplification (actually for tri-amplification).

In the case of the passive crossover allowing for bi-amplification, it does seem to sound better than using an electronic crossover.

I thought this would be the case.
The reason for this is probably that there is one less element in the signal path.I think my speakers will work fine in multi-amp configuration,but i have to try and see.There is simply no other way.But first i need to treat the room.This is the next stage.

I'm surprised that with a thread on solid state, monoblock, and bass, the Krell name only came up once! I haven't been fortunate enough to try any of the monoblocks (KSAs or FPBs)on my speakers, but I do have a KAV-300R and it's been able to give a lil nice tightness to my maggies, which or notorious for being a lil shy on the Bass part.

The bass is something that I do miss when I swap out the SS amp and hook up my Cary Sixpacs to the speakers.

Although the Bryston 7B does seem pretty legendary in this category. If I ever come across one, I might have to audition it with my Maggies.

I think there's something to be said for Mark Levinsons also...

You never mentioned your price range?

A nice trick with Maggies, at least with tube amps, is keep the speaker cables short, really short, like maybe only 6 inches. I've heard that make a profound difference.

Price range - well,it depends.Sinfonia is tri-wired.So SS monos will drive either one 12" woofer only (one connection),either that 12" woofer plus another 12" woofer and one 7" mid-bass (other connection).

If 30 W/ch 320B XLS SET proves good/very good in bass,then i will let it drive tweeter and 2" midrange,along with one 12" and 7".
That way i will not sacrifice anything in midrange.Bass will still be suficcient if i connect a rear 12" woofer to SS amp.This woofer is configured for the deepest bass.
In that setup i will not go above 3-4 000 $ for SS monos (used).This is top,but i could also end up paying even less.For example ,Wired4Sound 250 W/8 Ohm monos seem good enough for that option.Class D shouldn't be a problem there.

But,if SET amp shows only treble and midrange good enough,that i have to go with more expensive SS amp,as it will be powering both connections (7"+12" and 12").
Then i have to spend more....Pass seems a way to go then.

I will know which way to go when the monos are built.But i have a great confidence in a man who will build them for me.
I think they will prove good enough for everything.I think that tweeter and 2" mid and 7" and front 12" will end up powered by these.I have a great respect for the knowledge of Siniša Trlin.I was lucky to meet him,he thought me a lot about audio.
Since there is no limit in $$ for building these,i think they will be able to stand side-by-side (or surpass) any SET amp,regardless of price.I am very curious to hear them.
Patience is a virtue.

Brystons are great for bass the 7bsst is a great call above, also although you said you don't need power, the Spectron Musician (maybe an older version) are bass monsters, I love the Mac 7270(? can't remember the exact number, it's been a while) for pure bass reproduction.

good luck
