    Are loudness and tone controls necessary?

    in 2-Channel Home Audio

    To jbsl, and anyone who knows,

    Wow, are Luxman components still available? I thought they went out of business, at least in home audio. I looked high and low in 2004, trying to replace one that self-destructed (after 24 years of hard use). Here's why I'm interested:

    The only tone controls I ever really liked were on a c1980 Luxman component; there were many choices of turnover frequency. I generally used the very highest turnover on the treble, which produced a very steep curve that had low magnitude --- at full clockwise (almost never used) it boosted by only 7 dB at 16K Hz (as opposed to 15 to 20 dB on many treble controls). For almost all recordings I used about a 2 O'clock position, with the highest turnover, which added a little spice to the Klipschorn K-77 tweeters in my room, mostly at 10K and above, sloping upward to a maximum of just a few dB (about 3, if I remember correctly) at 16 K --- very subtle, but distinctly audible, and very welcome. I used the bypass switch to compare, and nearly always preferred the slight boost with clean recordings.

    A few dull recordings were helped by more boost, but most remained the ears of sows.

    I believe they are still made and sold today but only in Japan or overseas. I also believe they only produce the very high end of home audio.

    I also agree with your assessment of Luxman tone controls. The L-580 integrate that i use as a pre does an outstanding job IMHO with tone controls.

    So for those of us who do have tone controls, is it better to leave them at the neutral (12:00) setting? I know it's all up to me in the end, but if I wanted to somehow bypass the tone controls, would the neutral settings be closest to, well, neutral?

    Well with the tone controls bypassed it is more of a straight line approach. So the answer to your question would be yes.

    And better to my ears sonically than some "hometheater" amps Carl.

    Ouch. So basically the PLX series is good for either subwoofers or tv(Hometheater). Thats not how i see it with this SRA series. But then again higher grade parts and closer tolerances usually do lead to better designs. Cant recommend the PLX series i have never heard it.

    As far as how these folks feel about preamps. The SRA series works nicely with either. But these are my ears and my opinions driving chorus II's in my listening room. I'm having fun and enjoying the tunes and really thats what its all about to me.

    No.

    What I was trying to convey with my comment was that the QSC PLX series works even better with horns (for music) than some higher priced, solid-state, multichannel consumer amps out there - at least to my ears. Some people who add separate multichannel ss amps add them due to benefits with musical passages (SACD/DVD-Audio) as opposed to just HT. After all, if HT is your main focus, there are some nice quality receivers that will fit the bill nicely with horns.

    Nice. I misunderstood.

    I did not mean to imply that the PLX was good only for either subs or HT. In fact, both of my PLXs are used in my main system, which is 95% music and 5% movies, and these amps even put some tube amps to shame - relative to horns.

    Wow. From a 2 channel tube enthusiast that is saying alot.

    You continue to laud the SRA series as being superior to the pro PLX series. I also cannot confirm or deny any sonic differences (or not) between the two lines because I have never heard the SRA series. I can say that the fan noise is negligible even with the stock fans, and I have no qualms about run this particular pro amp in a home setting.

    That would be Bob Lee who said better parts so i doubt its just a changed fan. And he also states the PLX series is the next closest thing you will find for home environment. I dont believe anyone was in more disbelief than Bob of the SRA demise.

    When researching QSC amps last year, I also recall comments of those purportedly knowledgeable about the respective amps that believed that QSC just rebadged most of the PLX technology, removed the fans - and tripled the price to attempt to appeal to some home audio consumers. Most felt there were not any sonic differences between the two amps. Perhaps even if there are some actual sonic advantages to the SRA series (other than the absence of a fan), it was this public perception that contributed to a lack of sales and the cancellation of the line.

    Well for a public percepted pro amp to cost 3 times more for the same power i can understand. Seems as you look around the folks that own them keep them.

    Carl.

    Just let me state i am not saying anything negative of the PLX line. My opinion wouldnt be worth anything since i've never actually heard one. If they do indeed sound like the SRA series then i would recommend one. The reason i purchased a QSC amp in the first place was from what i have heard here on the forum. Are they the end all in amplification,noway but they do sound good.
