System Upgrade


Leben CS600; Harbeth Plus 5s; PS Audio with Bridge II linked via Blue Heaven USB; Chord Clearway interconnects and speaker cables (not bi-wired).

Sounds good but "flat" and I find myself having to turn up the volume almost halfway to get any "presence".

What am I missing, if anything?

Than you.

The reason I bought this amp and speakers was for the one mentioned just now by ghasley. Problem is, when I wired it up with my current setup I ran into the “flat” problem and wondered if I missed something. When playing Prokofiev’s Romeo and Juliet Decca recording it is stunningly absent. That said I intend to try some of the suggestions above and will report back. Thank you. 
@mdmdwyer, Prokofiev’s "Romeo and Juliet" is of course a work having exceptionally wide dynamic range. And although I don’t have a recording of it on Decca, given that it is on that label I would suspect it has been well engineered, meaning without large amounts of dynamic compression. **If** the "flatness" occurs mainly on recordings like that one which have particularly wide dynamic ranges it would seem to suggest that lack of power may indeed be the root cause of the problem.

BTW, I have the Leinsdorf/LA Philharmonic recording of Prokofiev’s "Romeo and Juliet" that was done by Sheffield Lab, on their direct-to-disc LP and also on CD. Some time ago, out of curiosity, I examined the signal waveforms that are on the CD using a professional audio editing program, and determined that it has a dynamic range (the difference in volume between the loudest notes and the softest notes) of about 55 db, which is simply incredible.

Good luck. Regards,

Jeff Day for one. Many more use the amp with other speakers, floorstanding or bookshelf/standmount, high sensitivity or medium sensitivity. The Leben is exceptional. While I also like Harbeth alot, the SHL5 isnt going to play 120db BUT, it should sound three dimensional, layered, etc. The best I’ve heard the SHL5 sound was connected to Leben. Also @donvito you can google Leben and Harbeth and there are many variations on the theme.

I am certain there is a mismatch, a misconnect, a malfunction or a software/digital issue. For once on this site, it isnt the equipment unless there is a need for a repair.
No problems with the headphones test - quite the contrary. 

Runs better at 8 impedance vs. 6.

Using power cables provided with original units and a cheap 6 way Westinghouse adapter. 

Ethernet cable is a Supra Cat 8 from Sweden.

Looking into demoing a few amps and cables.

And yes, I am using Roon to run Qobuz.
