A question of bass... Several actually.

Absolutely agree with Tvad. The ProLogue one is a great little amp, but much better suited to the Rega's

In a recent thread I suggested the following amps to power a Totem speaker the poster was having a difficult time driving with a 100 watt SS integrated.

I would add to this list the new NAD separates: the C 165BEE Stereo Preamplifier and the C 275BEE Stereo Power Amplifier. The integrated C375BEE will be just a tick less sophisticated than this pair.

These are very powerful, musical, relatively cheap and would mate quite well with the Dynaudios. I have heard the 72's with the precursor C 162/C 272 NAD separates to these new models, and it was the first time I decided I liked Dynas. And I liked them a lot. The NAD C 162 and C 272 separates or c372 integrated are still available a few places new at a steep discount, and occasionally used, and while slightly less powerful and resolving compared to the latest versions, would drive the 72's quite well.

The Rega/ProLogue one combination will sound really nice, but will never be a bass monster. The 72's are much more capable of life-like bass sonics if driven properly. But that would mean a different amp - and not necessarily a super expensive one. If you want both your highly nuanced mid range and treble with your a$$ kicking bass too, check out the list in the thread above.

Good luck.

If you want to keep the mids and highs of the Primaluna, and still get respectable bass, you have to have a set of speakers that are designed to allow the amplifier to do just that.

For more information on matching equipment see

Dynaudios for the most part are not designed for tubes, being Voltage Paradigm technology. In addition, their efficiency is so low that you will really need about 600 watts to really make them work if you want life-like spls.

Audiokinesis has made some very impressive speakers that also play bass on lower powered tube amps. Coincident is another, but you might be looking at used to get in the price window you have.

I have a pair of Dyn Aud 82 in the garage waiting for new amplification. Big bad and beautiful. Picked em up locally on Craigslist for a good deal, in great shape and all pkging. Let's put it this way, I have a pair of Bel Canto Ref 1000 mkii on the way. Can't wait to throw 1000 watts and outrageous damping factor to those woofers. The owner's set up did not sound great--and made the Dyns sound flat like you said earlier. He had an old parasound amp and a crappy phillips cd changer for a source. Curiously for a purported a/v installer, he had the gain set too low too, which limited the current from the amp. But I really liked their imaging, soundstaging, smooth treble and build quality. They seemed to have potential. They got my toes tapping--always a good sign in a speaker, especially a big one-- and I decided to take a chance that what was missing from the equation was good equipment with enough current to make em sing. This won't be the most revealing and refined set up, but I think it's gonna rock when I turn it to "11". I think it is going to be fun. I also considered a parasound halo a21 which does well with these speakers. But I really wanted to throw some power to em. I'd suggest the same for the Aud 72s. Good luck and have fun!

Dear Ranechak: +++++ " Is it necessary to spend $1000 per speaker or over to have audible, palpable, appropriate bass reproduction? +++++

IMHO it is necessary for low bass with good pitch, definition/precision, no overhang, etc, etc.

the 72's goes down in room maybe no more ( usuable ) than 50Hz that belongs more to the low mid bass that to the low bass. Btw, IMHO the " diso dancing bass " it is something totally different: in an audio pure concepts that is not bass.

About what the salesman told you that a separate sub is not appropiate on high end I think that he has a misunderstood about.

+++++ " doesn't putting the amp output into a sub's crossover to be split to satellites compromise imaging etc? " +++++

IMHO the answer is NO. As a fact it help to those speakers and your whole quality system performance achieve a level that you ever dream about.

If you can please read what I psted on the subject, maybe it could help you:
