    About b&w 683s2 question for Amp

    Hi.
    I have the amplifier <yamaha as-701... 2x100wrms in 8 Ohm>. The question is... is the powerful amplifier enough for this speakers?
    This speakers is in my budget and I want to buy for this.

    I have 683S1's and have went through 3 different forms of amplification. Rotel:

    RSX-1058 2x100 watts (surround receiver)

    RB-1080 2x200 watts (stand alone amplifier)

    RB-1090 2x385 watts (stand alone amplifier)

    With each upgrade everything improved. I would get something as powerful as possible. B&W speakers love power. The RB-1090 effortlessly drives my 683's to ear splitting levels and it only gets moderately warm. The 1080 and the 1058 (while very good at normal levels) would eventually get to hot and shut down if I had it running very loud.

    Power. Get as much as you can.

        Thanks for your answers.
        I know that they want more power but for now I want to ride with the as-701 and if they have good results.
        Later I would do some upgrading possibly Rotel 1570 or Yamaha as-1100.
        The question is if it's okay now with no problem to the speakers and as-701

              Hello again after a few months.

              Well, the as-701 does not have the power to drive the 683 s2. I want to upgrate the amplifier.

              The speakers want a lot more power and that's why I want to buy the ra-1592 to get 100% of them. Is this speakers ok with that power ... 2x200 into 8ohm?

              What is your opinion, going for ra-1592 οr something else?

              I've read a lot of comments for Parasound, Hegel and some still but I think the rotel is above from them.

              Sorry my bad English

                  Hi BWLover...

                  Yes I believe the amplifier is fitting with the power it has for my speakers.
                  It's the upgrading I'll make soon without the wrong choice again.

                  200 watt i think is ok, RB-1090 yes ... it's a monster ... i'm jealous.

                    You'll notice the difference between your Yamaha and the Rotel. B&W speakers love current and the Rotel will provide. Enjoy!

                      Yes, the current is really what the speakers need ... that's missing from the yamaha.

                      After the purchase I will come back for impressions. tnx :T

                        Hello everyone, back again.

                        Now I've bought the Rotel but there's a problem with their sound.
                        The sound I have seems to me poor, without power, the bass sounds as if they are coming out in front of the speakers, medium / treble not enough.
                        As if you have set to - (minus) bass / treble. This is where I play cd / pc / bth / tv
                        The speakers I played with yamaha as-701 (100wrms) for one year very satisfying but... what I wanted it more !!!

                        Anyone knows where the problem let's help find a solution.

                        Well the system now is:

                        rotel rc-1572
                        rotel rb-1582 mk2
                        b&w 683 s2
                        cd teac

                          What do you mean "the bass sounds as if they are coming out in front of the speakers"... as oppose to what??

                          Have you checked and double-checked all the basic things like speaker connections, phase inverted, the jumper between the high/low drivers, etc?
                          Does it sound this way with all sources? CD, pc, bth?, tv.. all of them have the same problem?
                          What Teac cd player do you have?

                            audioqueso tnx for your answer.

                            All basic things it's ok and the cd player is Teac cd 3 (it,s for upgrate). I thought of a speaker jumper on the speakers and pull out the metal. It will be better?

                            I do not know if I say it right or not. The loudspeakers first with the yamaha were playing more full with the bass/treble at 0 when the volume is 9-12-14 o'clock. Now with Rotel (4 times the value above) the bass on +1 and the treble +3 for bit better.

                            I called a technician in my house and told me the sound is flat with the measurements he made afterwards in the audio system.

                            I do not know if it's right in this audio system that bass / treble climb +1 or +2 or+3 ... to i have good sound

                              Sorry for the late reply.

                              "I thought of a speaker jumper on the speakers and pull out the metal. It will be better?"
                              Do you know what that's for? If you are running one speaker cable (with one black/one red connector), then you NEED that jumper. You can replace the metal jumper with something else (like after market jumpers).
                              If you remove the jumper and not use double-run of cable, you will not be hearing either the tweeter or the lower frequency speakers.

                              What you are describing between the Yamaha and the Rotel does not seem like anything wrong.
                              Quite frankly, the technician telling you that it sounds flat... is probably accurate. Rotel make their products to be as transparent and flat as possible. That is the desired outcome from most Rotel customers. Hence why people buy Rotel.
                              Yamaha (not all products, but most) do adjust the freq curves for a more mainstream sound. Stronger bass and treble. Because the majority of their customers desire that "more fuller" sound. Audiophiles will tell you that a flat frequency range is actually the most accurate. Technically, that is true.
                              However, it may be that YOU like the sound of the Yamaha more.

                              Do you still have the Yamaha?
                              I suggest you try this.
                              See if the Yamaha has a "pure audio" type of mode that bypasses all processing (meaning no EQ adjustments, sound enhancements, etc).
                              Compare Yamaha's "pure audio" mode vs Rotel's "pure audio" mode. That should be the closet real comparison between the two.
                              With absolutely no adjustments (speaker distance, EQ, etc), what you would be hearing is how good the Yamaha's internal components + amplification section is versus Rotel's internal components + amplification section.

                              At that point, see if you hear the difference. See which one you like more.
                              Again, just from what you wrote, it doesn't really sound like something is wrong with the Rotel. It sounds like you may be use to the Yamaha sound and prefer that sound.

                                I've changed the speakers jumber and I think, I see a difference for the better.
                                You are right, Rotel makes their products as transparent and flat as possible. and with yamaha have a more common sound with stronger bass and treble.
                                After a lot of reviews I realized that it is really so right. This change of amplifiers is great with each other and I rather have been I had learned differently
                                All I need to upgrade quickly is the pre/end power cables and a good mains conditioners (Supra, GigaWatt...)
                                Some suggestion ??

                                The yamaha has been sold.

                                  That's a whole new other set of questions. lol
                                  You should probably read and do a search for those particular questions.
                                  You will probably find more answers compared to the number of replies you might receive to this thread.
                                  If you don't find what you're looking for, then start a new thread with that question.

                                  Good luck.
