What can I do to improve my 2nd system?


My 2nd stereo system is in my 14 ft x 18 ft bed room. The system is placed on the short side as shown. The sound path is laptop/CD/SACD player -> DAC -> power amp -> speakers/subwoofer.  All the details including the placements and cabling are shown in the picture.  The subwoofer is connected from DAC to sub. line-in and line out to power amp thru a build-in HPF fixed at 80Hz 12dB/Octave, which I found the best way for integration bet. the main and sub. The bookshelfs are slightly toed in.  After adding the sub., I like the almost full-range sound out of this system but wonder what else I could do to further improve it.  Any advise is appreciated.

The above principle is another reason to get better speaker stands, and when you get them make sure your speakers are firmly anchored to them. I’d even put some lead weights on top of the speakers.

@lewm that is an interesting position on vibration isolation for speakers. As more and more high end speaker manufacturers are using devices like the ISO Acoustics Oras as standard equipment for isolation.

I will stick with what the QLN and Magico engineers built into their product. Also can not deny the science in the Townshend ISO platforms.

May be the case for ELS speakers and ribbons..

I have no idea what QLN or Magico do.  Can you elaborate?  I cannot believe that either company would countenance placing rubbery supports under their speaker cabinets, but I am all ears.  I have a better idea about Townshend ISO platforms.  They seem to constrain speaker movement while also claiming to isolate the cabinet.  I am not preaching against isolation. I am preaching against mushy or springy feet that allow the cabinet to move in response to a musical transient.  How could that be a good thing?  Has nothing to do with the type of speaker, in my thinking.

Not all speaker manufacturers….but if ya throw time and phase out w trash, what’s a bunch of doppler distortion ? It’s product specific, in the OP system, might help…

Guess you need to look at their websites as well as PSB……

I agree the spongy stuff is not ideal. But the times they are a changing as is engineering.
