Vandersteen 2wq with Mccormack dna .5

Fellow audiophiles,
If there are folks out there using A Vandy 2wq sub with Mccormack DNA 0.5 amp then then I would like to know what value of crossover is working for you. I have tried 100k, 75k and 50k fixed crossovers and it all sounds the same to me. I have the crossover box and played around with different settings but haven't quite felt that 'aha' moment. I have had this combination for over a decade and the system has been used in various homes in rooms of different sizes. It has sounded different in different settings but has consistenly left me wanting for more. Am trying to figure out if there's something that is truly wrong or whether I should stop wasting my time and live with the way it sounds. Any feedback is appreciated.

Bob,
Thanks for the tip. Will try to go a level higher and see if there is any difference. I am not using the M5-HP. I have three sets of fixed crossovers (100/75/50) that I bought from Vandersteen/ebay over time. That’s one of the reasons why it also gets cumbersome to keep toggling between the values.

I will call JohnR and pick his brain on this topic.

OP - Great advice from gdnrbob!  He is right about the lower the crossover setting the more bass from the sub and he is also giving you stellar advice about talking to Johnny Rutan.  As far as I'm aware few people on the planet know as much about Vandersteen's and set up as him ( with the possible exception of Richard V.)

I haven't used the fixed crossovers, but the M5-HP. So, batteries shouldn't make a difference. The DNA.5 is rated at 100K ohms, so you should be  good to go considering you have 100-50. Why you aren't hearing differences is troubling to me. Once again, Johnny R. should be able to sort out the problem. 
If you can't find him, let me know.

Bob/hifiman5,
I haven't got a chance to connect with Johnny R (time difference between the west coast and NJ is always a challenge) however, I disconnected the 2WQ and am just using the 2CE Sigs II and it sounds much much better. Not sure if it's my room acoustics, the crossovers or the fine tuning but the quest will continue. However, for the moment, I am happy with what I am hearing. Maybe that the bass was too much for the space... Will try the sub with the 1Cs and see what I discover.

Oh, that’s weird.
If that is the case, perhaps you need to go to a higher setting, like 150k ohms. Like I said, (and Johnny), this is something you have to test out yourself to find the right balance.
As you are on the West Coast, why not call Mr. V. directly? He responds, usually the next day.
He helped me with my setup. In fact, when I called and told him the subs weren’t producing any bass, he responded quickly, but was a bit rushed for time, he even called back the next day to help me trace the problem- This, despite my being a buyer of used equipment. (It turns out I had the settings too high).

I can’t say how highly I think of him and his company.
