Karsoncookie Posted May 9, 2016 Author Share Posted May 9, 2016 The whole reason for this post is,----- years ago I had this Yamaha receiver feeding a pair of LaScalas, and it was good. But then, I replaced it with a pair of Adcom 300 watt monos, and Adcom pre. MUCH more chest hitting. That was very able to make the woofers violently slap (overexcurse sp?) if I went too stupid nuts on the volume. I know all about SPL, differing time exposures,permanent hearing loss, etc. Thank you. So now I want to regain that with a bigger amp, but needing to keep costs LOW, wondering if I can control it w the old Yamaha. So that's the whole story. I don't listen for long periods of time, but I LOVE that "fix" of like just one dynamic song at very high volume, I want to feel those drums in my belly and chest like I'm in the bleachers at an NHRA meet.

Karsoncookie Posted May 10, 2016 Author Share Posted May 10, 2016 OK, so I see a few options in this this thread here to feed a big amp, possibly like Crown K2. Of course, first, get a separate normal Pre amp. $ I don't have. Then, not in any order, Headphone out w wye splitter to two RCA's. Speaker outputs to attenuator like the previous in thread Ebay example for like $7, Shitt passive control (cheap, but I lose my "tone" functions that I want to retain) Possibly I missed any other option. So what is best bang for the buck?? lars Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted May 10, 2016 Author Share Posted May 10, 2016 Way more basic than most of you folks, but good enough for me. Just remember please, I was VERY happy with the stock LaScalas and the Adcom mono amps, with the old Sanyo CD player. I DO not need to upgrade from that.

Seadog Posted May 10, 2016 Share Posted May 10, 2016 Not sure about the answer to the question, but I bought (and still have) a Yamaha R8 in 1985 - that's 31 years ago! So I guess it is a 31 year old question . I have the manual somewhere. I will try to find it and research the question. BTW the R8 is not a bad receiver (85 WPC). I use one to power the front mains and another for the front center (one channel) for my HT (all Cornwalls). I have powered Lascalas with the R8 and while not as good as say an HK Twin Amp integrated amp, it is not a bad sounding solution for an integrated amp.

CECAA850 Posted May 10, 2016 Share Posted May 10, 2016 Also, Crown is a commercial amp, not a consumer amp - so there would be an impedance mismatch. An Art Cleanbox will take care of that. 2 Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted May 10, 2016 Author Share Posted May 10, 2016 The kindness and searching follow though of "DeanG" has above provided the details of the R8 manual. Regarding the jumpers - Note--------- it says - "Prior to tone control" So I lose that. Lars Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted May 10, 2016 Author Share Posted May 10, 2016 Somebody please comment - I live in the Woods and have NO ability to audition other systems - Even though my speakers are "high sensitivity", What will I gain from a majorly higher wattage amp? Won't I get way more "punch"??? Lars Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted May 10, 2016 Author Share Posted May 10, 2016 I think,I know about, maybe missed something, wrong, of feeding the highly sensitive Klipsch Heritages and "clones" (that I think I kind of have) with low wattages. But I want it to hurt, like enough to change my heart rythim. Am I nuts? Lars Quote Link to comment Share on other sites More sharing options...

Scrappydue Posted May 10, 2016 Share Posted May 10, 2016 Consumer and commercial gear does not play well together. This relates to gain structure. is this regarding older gear? tons of people are using pro amps now with receivers or home processors.

Quote: When it comes to adding professional gear to a home audio system, the fly in the ointment is their vastly different signal ranges. The mean operating signal level of pro gear is +4 dBu, while the average for consumer equipment is -10 dBV. The dbV and dBu values aren’t readily interchangeable, but they can be converted to a common standard, Vrms. The consumer -10 dBV translates to 0.316 Vrms, while the professional +4 dBu translates to 1.228 Vrms. So you can see that the professional signal reference is over four times higher than the consumer. In real world use this translates to a difference of 12-14 dB (depending on which information source you trust). Since consumer and pro equipment have such a tremendous difference in average signal levels, it should be immediately obvious that the chance of achieving a textbook pro-audio-styled gain structure in a mixed system is nil. Nevertheless, a cadre of home audio enthusiasts presumes (beyond reason) that a paradigmatic gain structure is attainable in a mixed system. It merely requires keeping signal levels as high as possible throughout the signal chain. This, we are told, is the way to optimize dynamic range and signal : End quote An art cleanbox will provide pro electronics with the voltage required to drive it to maximum output when using consumer level electronics to drive them. Heck Dean, even you used a QSC amp to drove your RF-7's. Currently I'm using 4 QSC amps and one Behringer amp in my HT with a consumer pre-pro with no issues.

Deang Posted May 10, 2016 Share Posted May 10, 2016 (edited) I tried a lot of different things over the years -- some were better than others. Things that sound better than others are better than things that don't. Just because the information is six years old doesn't mean it's false. You can hook a mishmash of gear together and make it work, but that doesn't mean it represents the ideal situation, or will contribute to the best 2-channel sound one can afford. The Cleanbox was part of a failed experiment. It really wasn't all that clean, and I eventually ran the QSC straight up using just the gain controls. This was around the time that I started listening at much lower levels - and I finally dumped the setup. If you want loud, clean and musical - you better be ready to pony up the dough. Half *** measures aren't going to get it done. Edited May 10, 2016 by Deang Quote Link to comment Share on other sites More sharing options...
babadono Posted May 11, 2016 Share Posted May 11, 2016 You should have no problem feeding your K2 from the headphone jack. You will still have a volume control that way. Those speaker level to line level thingys are cheeseball POS that I would not want in my system. YMMV. The K2 has a sensitivity switch on the back and gain controls on the front. Don't be shy about adjusting either one. Quote Link to comment Share on other sites More sharing options...

Karsoncookie Posted May 11, 2016 Author Share Posted May 11, 2016 I guess, silly me, I am still looking for substantiation or oppossite of ------ If the huge amp will give me that "NHRA" belly turning feel that a smaller amp will not. Ya, I know Heritage, and I guess my rig, are high sensitivity, so we're already ahead. Still, folks talk about brief "headroom " capability. This may be, in laypersons limitidly educated terms, what I'm talkin about ?? Lars Quote Link to comment Share on other sites More sharing options...
