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.

You can also adjust upwards (above 100K). I used the M5-HP with Vandy 3a sigs and Treo's. with a DNA-1-which has 100K ohm. I definitely heard a difference between 150K and 75K, with the bass becoming more pronounced as I proceeded lower.
1 question: how old are the batteries in the crossover? Are they near expiration?
Lastly, I would PM or call John Rutan at audioconnection (that's his Agon ID). He can give you detailed info on how to set up the subs/speakers far better than I can.

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.

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.

You can also call SMcAudio.
Pat usually answers the phone and can help you. McCormack and Vandersteen were very close for a while, so they have lots of information to provide.

If you find the bass overwhelming, I would go to a higher impedance setting. The 2w sub should be a very subtle presence.
I ran them with a pair of 3a sigs and had no issue with the bass being too high. Quite the contrary, it worked seamlessly.
