Have compared MS150s with Pentalabs - not quite the same. MS150s have much more detailed bass but the top end shrieks when very loud. I have found this with all the speakers using the tweeter like this - could have course have been the BM8000 but it doesn't do it with my M100s. For normal to loud playing it is very good though. They are very large though - Pentas fit in a room much better and if you really want more detailed bass, add a sub-woofer.

Thanks Peter

I ran the BV Pentas for some time with a Cona hooked up to the second speaker output on the BM 8000, and the bass was impressive if a little muddy.

Space isn't a problem. Finding some MS150.2s might be though.

I don't tend to play music at insane volumes - nothing above 3.7 usually. Out of interest, where was the volume setting when the MS150s started to scream?

Loud!! Clearly distortion though whether it was the 8000 or the tweeters I couldn't say. At sane levels, MS150s are excellent and the bass really is noticeably better than Pentas. I use a BL2 with my Pentas which is fine though it gets a bit excited at high volumes !

Thanks Peter

Some better bass would be appreciated, so perhaps I will put some feelers out for some 150.2 + stands :)

I am enjoying this thread!  I have an 8000 system currently paired with Jamo X870s.  I don't use them as monitors, but when I'm about the house, I do use them to listen critically to my DJ mixes of electronic lounge music.  I have to say they do a stellar job.

I'm having a set of RL140s refurbished, and I'm afraid they won't compare favorably to the Jamos (comparatively small bass drivers).  I also have a set of Penta 1s coming to me, which will need a bit of love in order to be brought up to listening condition.  In addition to those, I think I'd like a pair of MS150s just to complete the 8000 set.  If I keep the Pentas in the living room, I'm thinking a Velodyne subwoofer might provide the missing oomph.  Even new, Pentas were definitely lacking in the bass department.  Not sure how B&O made that obvious misstep.

Pentas + Velodyne subwoofer may sound the best, although the MS150s appear quite formidable on paper.  RLs may be relegated to office or bedroom duty (background listening).

Thoughts, criticism, jeers, random ridicule welcome.

Hi John

I don't know if you've heard a pair of 150's before - think I got mine after you'd been to my house - but if you want to pop down to have a listen you know you'd be more than welcome. I use a Beocenter 2300 and a Quad 405-2 with mine. 

Cheers

Nigel

 PS - They're not for sale!

Thanks for the comments guys :)

It's always been in the back of my mind to look for a pair of MS150.2s, but they are so hard to find in the UK that I settled on BV Pentas when I bought my BM 8000 a few years back. The last fully-fettled pair I remember seeing come for sale were some that Chris Metcalfe sold on eBay about 3 or so years ago, so I suspect the wait might be a long one!

Nigel - I might just take you up on your offer next time I am in Nottingham. You had the 2300 and the Quad gear last time I visited, but definitely not the 150s as I would have remembered them!

Ah - probably had a pair of Mission 753's. Very good speakers, but nowhere near the depth of bass of the 150's.

Cheers
