Ok let me state some thoughts which led me to ask for difference between 250-2 and 250dr.
a. Current system is good and I enjoy the sound especially the signature MA sound which has clarity and clean music. Sometimes I do feel there is shortcoming in bass i.e. not enough punch in low volumes (25-30) at which I listen to always. (Part of living in apartment lifestyle)
b. That led me to try bi-wire cable as MA manual suggests use bi-wire to improve bass. Audio quest rocket 11 did not change the situation much.
c. Then I read about 250dr bi-amp on this forum with nova. And I found second hand 250-2 was on offer for 1500 USD which is in my budget. 250 dr is twice the amount.
Now this brings me back to above suggestions , should I be looking to replace the speaker or try nap 250 bi amp?
Patla unless any 250.2 has been recently serviced, it will be at least twice the age of Nova, not an ideal combo, if the aim is low volume listening. Only add an amp to Nova, if the room is large; even then not ideal.
Otherwise imho, if speakers donât give the required sound/bass at low levels, then headphones would be a better option. Donât know prices in your location, but a s/h Atom HE with headphones, might be available for a little more than 250. Headphones lots of choice - try search for what forum members have experienced. Keeping it simple will be win win.
edit - one option not so far mentioned, is to add a sub. No experience here in 2 channel use (sub in av system), but there are several threads on forum and the setup has its fans. Carefully set up, it may be vastly cheaper than other approaches and affords a better level of control, if you source a quality unit.
Well, an early 250.2 will be almost 25 years old. If it hasnât been serviced, it certainly wonât sound its best - you can double that $1500 price to get it bought, paid-for and re-capped.
