I would like to report that my Dhs have taken a remarkable turn for the better, specially the sub performance. Initially it was a bit boomy, but now once I start the music I am unable to walk away ! the bass is now bit softer, tighter with a diffusive sense of weight to it without being soggy. It just fills the room remarkably well with presence & authorityJust added this subwoofer 12" to my heritage specials.
although I had some bad experiences with subwoofers, this sub integrates very well.
not just with movies, but also with music, I have it on always!
crossover very low, 40hz gives me a good result. I found this subwoofer (800 euro) because I read this forum, so it is a bargain for such a good sub. I think the other subs I tried were too small for my room.
Thanks for the advise folks!
My initial system was
bluesound node 2 streamer/dac --> NAD c298 power amp -->DHs speakers
The 1st change I made was to add an external DAC
bsn2 streamer --> denafrips Pontus ii dac --> NAD c298 ---> DHs ..... I now felt that bass had started softening a bit ie more controlled ie the boominess was gone
The 2nd change I made was to replace the amplifier
bsn2 --> Pontus ii --> Schiit Tyr mono blocks ---> Dhs ..... I now felt that the bass improved more. It had a superior quality, weight and strength w/o the boominess
The 3rd change I made was to add a Power conditioner {denafrips bic 500}.
I used a noise meter to test the conditioner & although I cannot measure a noticeable difference in noise reduction, the base is now again much improved !
