    I am looking at purchasing some PMC OB1 speakers and currently have a Bryston 9B SST.
    I am thinking of buying a 4B SST to drive the OB1's (Use the force Luke :laugh: ) and then use the 9B SST to drive the rears bi-amped and the centre too.

    My question is will the 4B SST be a substantial improvement over the 9B SST?

    My room is around 4x5m and I listen to music and films at moderate levels.

    Id like to hear from people who have experience of the two if possible.

    Thanks

    Sounds like you've got money to burn. I'd be tempted to try the OB1's using just 2 channels of the 9B. Alternatively you could use 4 channels of the 9B to bi-amp the OB1's and then get a 3B SST to drive the rears. To be honest, biamping the rears sounds like overkill to me.

    Another completely different amp that might be worth checking out is the 6 channel Bel Canto Evo 6. I know that long term avforums member 'Lowrider' made the switch from Bryston to Bel Canto a while ago and hasn't looked back.

    Don't hesitate at all. I originally had PMC OB1's bi-wired from the 9BSST with a CB6 Centre and DB1's at the back. I then upgraded the rears to another pair of OB's which I had bi-amped from the 9BSST as I felt that the extra power was needed in addition to running the bass/ mid/ treble separately. This meant I needed more amplification to run the front speakers. The upgrade to the 4B made a staggering difference running tri-wired and I'd recommend this configuration over bi-amping the 9BSST anytime. There just seems to be alot more cohesion by running two large amplifier modules as opposed to four smaller ones. I sold my OB1's and 9BSST now but still have my 4B as (in my opinion) it's the best purchase I ever made.

    . . . then there's the option of the 6B SST running the front stage, or 2 x 6B's tri-amping the OB's, or 3 if you get a CB6, or a myriad of 7B's, but I might be getting a little carried away here.

    Thanks for your suggestion Matt, I hadnt thought of that. :blush:

    Mr Merrick, you must have a very large room if you can accomodate 4 OB1's!
    Looking at your sig Im soooo jealous!!! :devil: :devil: :devil:

    I will only have DB1+'s as rears so bi-amping maybe a little OTT but its just a way of utilising all the channels of the 9B.
    I will be using a TB2+ as a centre as the CB6 is outside my budget at the moment, but maybe I will upgrade next year if the TB2's don't quite cut it.

    The addition of the 4B SST appeals to me as the OB1's seem to improve with better amplification.
    I have heard them being driven by a 14B SST and wow!!!!!!

    Apart from better cohesion, how else does the 4B improve on the 9B?
    Better bass, mids or sweeter top end?

    I was considering the IB1's but I dont think they will pass the wifey test!
    How much of an improvement are the IB2's?

    Thanks

    Don't know about the IB1's, but the IB2's are awesome.

    vizslaraner,
    Did you listen to any other Bryston amps before buying the 4B SST?
    I notice from your pics that your OB1's are very close to both rear and side walls, does this cause them to boom or thicken the midband?

    With your room size I would keep the 9B SST for the 5 channels...

    No. I auditioned them via a Rotel 1090; originally ran them at home via a Meridian 559; have now got them running via the Bryston - from which I won't be parted (unless I find a good deal on a 6B SST).

    To my ears no, but then some might think of your boom and thicken as a broadening of the midband. It's a subjective argument that's really a matter of personal taste; much like my toeing them in.

    PS
    My room is only 3m wide so you should have reasonable scope to experiment.

    These two amps sound identical, where they differ is in their ability to drive loads. It is all down to you size of room and the level you like to listen at.

    If you listen at moderate levels, in small ish rooms you will not hear a difference as both amps can cope. This is also the view of Bryston as well I believe.

    My gu hunch on the details you have supplied is that th differences will be SMALL.

    Thanks for all the comments guys :smashin:

    I have decided to let the speakers (once I get them) run in for a few months and then if Im not happy (I never am!) I will try the 4B SST at home.

    Has anybody ever listened to Plinius amps?
    Ive read some good reviews but I tend to take those with a pinch of salt.

    Anyone had any experience of using Bryston 7B SST to drive B&W 802's - what's your verdict?

    caleb,

    I use 7B SSTs to drive my N800s. I find that the Nautilus range sound best at medium to high listening levels. My listening room is roughly 26' x 18' and 7Bs definately have better control over the N800s than the 4B SST or 6B SST.

    I previously used N802s with a single 4B SST and then 2 x 4B SSTs biamped. I really could not hear any improvement biamping.

    IMHO get the 7B SSTs and place them as close to your 802s as you can. I have mine under the floor in the basement with just 1' of speaker cable. Bryston recommend very short speaker cable runs with longer XLR I/C runs.

    Regards

    Gaz

    Thanks Gaz for your input,

    You have a very short cable run indeed - mine will unfortunately have to be bit longer at 1 metre - but still quite short in real terms.

    Just out of interest, what price did you pay for your Bryston 7B SSTs - our dealer here wants the equivalent of GBP 5000 for a pair!!

    Regards
    Caleb

    I did try the 200 wats integrated Plinius with my Sonus Faber EAII and it couldnt handle them, loose bass, etc...

    I had a Rotel 991, who also couldnt handle those speakers...

    Got a Bryston 4B ST, no problem, and later a BelCanto eVo 6, even better...

    lowrider,
    Maybe the reason it couldn't handle your SF's is because it was an intergrated as opposed to a power amp.

    I heard one of the power amps on tues when I was listening to a DCS Elgar Plus. The speakers were Wilson Sophia's and the amp seemed to have good controll over the bass. Very nice sounding indeed.
    It got me thinking about the Plinius Odeon. Damn!

    CBW,

    I'm sure the 7B SSTs will sound amazing in your system, looks like you already hear a difference.

    I look forward to the info and appreciate your help with this :thumbsup: .

    Gaz

    You'd be amazed at how many people ask that, but if you saw her in real life you'd immediately realise, from experience, that she isn't - no ridge and way too small.

    Mishka's actually a Hungarian Vizsla, hence the handle (Freya being a Weimaraner). Mind you I'd love to have a Ridgeback (I do know of a couple that are local) . . . and a Malamute . . . and an Akita . . . and a German Shorthaired Pointer . . . and a Long Coated Weimaraner . . . and a Large Munsterlander. However, at the moment it's likely the next two will be a Doberman and a Dalmation . . . so if you ever see a Dalidobe handle you'll know who it's likely to be.
