|   Would a Rotel 1075 amp be a major improvement over ??? | Biohazzard
May 6, 2002 7:27 PM | | Would a Rotel 1075 5 channel amp be a major improvement over the Yamaha RXV-2095 reciever? Why? |
| Not really!.... | nick4433
May 6, 2002 7:38 PM | | No because I believe the Rotel is 150W/channel and the 2095 is about 100W/channel. For you to hear a substantial power difference, the amp power should be doubled, i.e. 200W/channel.
If this was not the venerable Yammy 2095 and some other receiver, then the Rotel would have been a definite improvement not only in terms of power but also clarity in the lows and mids in particular.
However, the 2095 is a real solid receiver and that particular Rotel would not make any significant difference IMHO. |

May 6, 2002 8:10 PM | | b For you to hear a substantial power difference, the amp power should be doubled,
That is a 3dB spl change. I would not call that substantial sound level change but something slightly perceptable under some conditions, not all. A 10dB spl change is double the perceived loudness. |
| Agreed. :) (NT) | nick4433

| I want sound quality improvement....could'nt care about loudness | Biohazzard
May 7, 2002 8:44 AM | | Besides...the rotel 1075 is 120w X5...not 150w |

May 8, 2002 2:43 PM | | You are basing your opinion on an assumption and one that could very possibly be wrong, namely, that Rotel and Yamaha's power ratings are equivalent. My old 1985 Rotel RX-850 (30w/ch) plays louder without distorting than my sister's new Yamaha RX-V620 (100w/ch and her speakers are more efficient). Maybe in the good old days Yamaha made stronger amps than it currently does, though. If there is a manufacturer in the business (well, at least in the solid state line rather than tube products) that is more conservative about its amplifier power ratings than Rotel, I would like to know about it. |

May 6, 2002 8:12 PM | | If the power is as stated above, a 50 watt difference in those amps is not even 2 dB spl, barely perceptable at some bands and not at others. |
| Keep the Yamaha the way it is without the amp | pinetop
May 7, 2002 2:24 AM | | if it sounds good.The other posters are right adding the amp will make the 2095 a tad louder at best.Why would you want to add the amp?are you looking for sound improvement?or do want it to play louder? bob d |
| The reason is that I wanted better sound Quality. | Biohazzard
May 7, 2002 8:35 AM | | I don't care about loudness. Would the Rotel give me better sound quality? |

May 7, 2002 10:07 AM | | BIO the only thing the amp will do is amplify the sound from the receiver that"s it.As far as getting better sound no. bob d |

May 9, 2002 5:46 PM | | I have an RX-V1000 and I added a Rotel RMB-1050 for the main speakers and I noticed a slight difference (enough to make it worthwhile). The best way to describe it is that the lower frequencies seem to start and stop a little quicker than before. Bass notes are crisper and finish a little nicer. Can't really spot much difference in the upper frequencies. The FYI, the Yamaha is rated at 100 W/ch I believe and the Rotel is 70 W/ch. |

May 7, 2002 3:28 AM | | Depends on what speakers you have and what you are trying to accomplish. If you have inefficient speakers, it could make a pretty big difference. If you biamp with the new amp, it could make a HUGE difference. |
| I have B&W's for all five speakers and an ACI Titan ll sub | Biohazzard
May 7, 2002 8:41 AM | | 603's for the fronts, 601's for the rears and CC6 for center. I also have the ACI Titan ll sub.
I just want better sound quality for music AND Theater. I don't wana Bi amp the reciever with the Rotel amp.....besides, I don't know how to Bi Amp. |

May 7, 2002 9:49 AM | | Do you have the DM603 s2....s3?
Can't help very much without some specifics. I'll get to that in a second. First, you have a great sub. Tell me about the setup. Are you running the B&W mains on the small setting (in the receivers settings)? Are you just using the Yamaha's low level output (1 single rca cord going from the receiver to the sub) to the sub? I think your ideal setup (for your current stuff not including any new amp just yet) for this would be to set the 603's on the large setting AND THEN running the speaker wire from the receiver to the SUBS high pass input (speaker level inputs on the sub) and then from the subs high pass outputs to the speakers (continue to use the rca low level input as well from the receiver, don't change that!). So you will need 2 extra runs of speaker wire to run from the subs high pass (speaker level) outputs to the speaker terminals on your 603. Then use the subs high pass dial to transfer the cutoff to the 603 (I am guessing around 50-60hz). This will mean your 2095 won't have to push as hard to drive the lows. Let your great sub do that. Then re-calibrate using the radio shack SPL meter.
I am just trying to see if you have tried this before jumping on a new amp. This may satisfy you. The Rotel you mentioned will be better than the Yamy's amps but your speakers are efficient (90db for most B&W's), so it shouldn't take that much juice to push them.
Also, biamping involves the speakers. If your B&W's have 2 sets of speaker post on the back they can be passivly biamped. I am thinking you just won't be all that happy, regardless of the amp, with the 2095 as a music preamp. I could be wrong. What are your sources for music? CD player, dvd player? These could make a difference as well. |
| You were correct. They are the all DM series. DM603 | Biohazzard
May 7, 2002 12:23 PM | | DM 603 for the front, DM601 for the rears. The speakers are not the s2 series.
There is one single RCA wire going to the sub, which is called "Theater Mode". WIth that setup, I have to have the front mains are on SMALL, REARS are on SMALL and Center is LARGE or else no sound comes through to the sub. (With single RCA wire going to sub, if fronts and rears are set to LARGE, then no sound comes from sub)
Now you are saying to use 2 RCA cables to the sub? What would be the out put from the reciever? The receiver only has one sub out. Yikes!
Perhaps we can chat on AOL buddy box or something? |
| You were correct. They are the all DM series. DM603 | Chuck G
May 8, 2002 4:22 AM | | Biohazzard, you should set your center to SMALL as well for starters. Your sub doesn't have high level speaker inputs so forget about my prior ramble. The sub you have looks to be one of the harder subs on the market to setup properly. I would concentrate on getting the sub dialed in before going any further. Did you buy it locally? If so, did they offer to help set it up? Check out this article I found on the sub. I think you will see what I mean.
http://www.soundstage.com/entry11.htm
This article talks about things I am not real clear on (some of the filters etc) so I am not sure how much I can help with this. Do you have the spikes they talk about to get the sub higher off the floor? If not, that would be a start. I think most of your disappointment in the sound is a sub that is not properly integrated. Check in the sub review section on this site under the Titan sub and see if you can email someone who has this sub for better help. |
| Chuck...I forgot...Read this also | Biohazzard
May 7, 2002 12:33 PM | | The Titan Sub ONLY has RCA jacks on it. NO SPEAKER WIRE INPUTS.
The RCA Jacks are as follows....
Left and right for LINE LEVEL INPUTS
Left and right for LINE LENVEL HIGHPASS OUTPUTS
One single input for theater mode (The one I currently use), Which is coming from SUB OUTPUT on the back of the reciever. |
| Bio, I also thought the same question | flaco
May 8, 2002 6:51 AM | | Bio,
I also have the 2095 with B&W (cdm9nt) and posted the same question.I am also thinking of changing the amp(Rotel,ATI,Outlaw?)Is Rotel amplification different then Yamamha, or Outlaw etc? I thought that different amps produce a subtle sound difference due to electronics otherwise why do we read reviews that say that this amp was harsh or this was neutral and warm? As for your set up, I set the front to large,center and rear to small, set the sub to both. Since you cant adjust the crossover in the reciever, I use the cutoff of the Yamaha and turn off my velodyne crossover. Are you running into both inputs of your sub with a y connection? |
| Chuck...I forgot...Read this also | Chuck G
May 8, 2002 7:33 AM | | Biohazzard with this info....
"Left and right for LINE LEVEL INPUTS"
I would contact ACI via phone or email and tell them your specific setup (speakers, preamp etc). Also check out the manual (Titan) about the line level inputs. You may be able to considerably improve your setup by getting what they call "filters" (purchased from ACI and filtered at the right freq response for your mains) and using the line level inputs on the sub, in conjuction with your mains. The article I linked talked about a lot of this. Concentrate on getting your sub set up correctly for your setup. I think that COULD solve most of your sound issues. |

May 9, 2002 2:13 PM | | I'll toss in my two cents -
I have a Yamaha 2095 and NHT 1.5's x 4, an NHT AudioCenter One, and an NHT SubOne. The NHT's are relatively inefficient, at about 85 to 86 db.
The sound with this arrangement was thin and lacking all the good adjectives folks use to describe pleasing sound.
I added a Parasound 2205, a 220 watt x 5 power amp, and the sound quality improved incredibly. I now use all those good words when I talk about how it sounds. I am convinced that a high quality power amp can improve the sound of a Yamaha 2095 more than the power ratings would suggest.
Can you try a Rotel power amp and see what it does for you? I would be surprised if you were not pleased enought to purchace the amp.
Pls let us know how it goes! |
