    Does adding amp affect receiver?

    Nope. Assuming your RXV2400 has multi-channel preouts which I think it has, you can selectively hook only the 3 front pre-outs to a 3-channel power amp and enjoy the movies and the music without affecting the receiver's preamp section. Others i know actually converted their recievers with...

    cheap dvd players

    I have commonly encountered remarks in many fora that an entry-level SONY DVD player is one of, if not the worst DVD player you can get for the money. I probably wouldn't espouse that, but just say that an entry level Sony has the least features you can get for that price which many CHina-made...

    Bi-wiring and speaker calibration...

    Right now I only use my inadequate ears to calibrate. But I am in the market for a good SPL meter, maybe from Radio Shack. I use the Sheffield My Disc test CD's LF sweep to check on the transition between my main fronts and the sub. I think those THX calibration tools in many THX certified...

    Bi-wiring and speaker calibration...

    I bi-wire if only to increase the effective gauge of my speaker wires. And i don't use 4-wire cables as the capacitance between parallel wires have been known to attenuate high freqeuncies. Not that it really matters with small cable lengths, but i'd rather not gamble with it. Some...

    Speaker Efficiency

    It is possible the Boston VR950's sensitivity of 90db was measured in an anechoic chamber which should be rightlly compared with that of the Axiom M60's anechoic response of 89db. And since they're both 8ohms, that would make the Boston at bit more sensitive. But that wouldn't account for what...

    Is it just me??

    There is no doubt GREED is behind all these - squeezing the most derivative sales from a film. I used to hanker for a film's DVD release. So I would take their barebones first editions with great interest. Not anymore. I have learned to wait long enough, either for the new special editions...

    Yamaha RX-Z9 - av_phile hijacked thread

    I don't have to put anything in your mouth as what you were saying is quite clear and their implications unmistakable. That is my point and nothing else. Whether 2 ch or 5 ch the Acurus measures their power with the same conditions. I also have the multi-channel A200X5 and the A125X5...

    Yamaha RX-Z9 - av_phile hijacked thread

    You're absolutely right. Why should I care? There are really more important things in life, and in this hobby, to even bother aspiring to be policeman in the industry. Nope, I'm not interested in the job. In the same way I've pointed out how misleading some Pioneer universal players are...

    Yamaha RX-Z9 - av_phile hijacked thread

    Now that's very revealing, so they'd raise the impedance just to gain UL SAFETY certification?!? That means, even if it can drive 4ohm loads, the receivers are dangerously close to thermal runaway and exceed UL minimum requirements for heat dissipation to gain the UL mark. Tsk Tsk. Another...

    Yamaha RX-Z9 - av_phile hijacked thread

    I find that logic flawed. It is precisely in NOT stating both or all channels driven that they are deceiving the consumer. Precisely because any power measurement that does not drive all channels will yield a HIGHER power rating. And they nicely HIDE that fact to show a higher power figure...

    Yamaha RX-Z9 - av_phile hijacked thread

    The scant user's manual on my Acurus amps are very clear: On the A250: BOTH CHANNELS DRIVEN. On my Acurus 200X3: ALL CHANNELS DRIVEN. So what are you talking about? How can they not be capable of delivering all that juice when each of them consume a whopping 1,200 watts of electric power...

    Go ahead and enjoy. But i just hope you are getting what the tech specs said you should get as a consumer. Nothing less.

    Subwoofer cross-over frequency with small satellites

    If your satellite speakesr indicate the -3db roll off point, that would be a good place to start for the sub-crossover frequency. It would be a good idea to get a test CD like Sheffield's My Disc which has a sweep of LF to check the transition between your satellites or main speakers with...

    General question about power

    Pls take a peek at the back panel of your receiver and check to see the electrical power consumption that is indicated near the power inlet. That is an impecable barometer on the ability of your amp to deliver output power. There's this immutable law in physics that, simply stated, says you...

    Yamaha RX-Z9 - av_phile hijacked thread

    Gene, I hope you are not missing my point entirely. For all intents and purposes, I can be using only 1 watt out of my 250wpc acurus amp and that would be sufficient to fill my room. Anything above it might very well damage my ears before any of my speakers even start to fry. But that's...

    Yamaha RX-Z9 - av_phile hijacked thread

    Gene, I've read your excellent but subjective assessment of the Z1. There's so much in it that I can agree with such as the awesome preamp and digital processing attributes that the Z1 shares with many outstanding receivers in its class. But there is one review I think it missed out that...

    High frequency response(lack thereof)

    I once had a similar impression with my first Rotel RMb1066 amps. I soon discovered the tweeters on the Wharfedales were busted. Replacing the tweeters restored the trebel details. The Yamaha is perceived as a bright sounding amp by most members in our local forum compared to the Onkyos...

    High frequency response(lack thereof)

    I once had a similar impression with my first Rotel RMb1066 amps. I soon discovered the tweeters on the Wharfedales were busted. Replacing the tweeters restored the trebel details. Also you may want to look the room accoustics. There may be too much absorbent material eating away the highs...

    The sound of Amps.

    Just found this interesting thread. Keep up the exchange of ideas guys. Let me post some of mine. (1) Amplifers ideally should work as a "straight wire with gain." I think this is the highest end in amplifier design. Among different brands that achieve this end with the fewest...

    Is it just me??

    I've had the same experience. But rather than get pissed off, I view it with some grain of understanding based on my experience as a marketing man. This version after version release of the same film is purely a product of marketing strategy to gain or extend the saleability of a film. You...
