kenratboy Posted December 22, 2001 Share Posted December 22, 2001 Hi! I got a Sony STR-DE675 receiver today and it is WUSSY! It is rated at 100 watts (8 ohms, 20Hz-20kHz, 0.09% THD) and I am currently driving a pair of JBL HLS610s (6.5 2-way, 88 dB. sensitivity, 8 ohms.) I put on a CD that I know well and turned it up, and up, and finally all the way up (as in MAX volume level.) It was just barely loud; it was probably 95 decibels maximum. I checked all the settings, its on large speakers and all of that, input is all of the way up, etc. The same went for my headphones, not enough volume, even on maximum. Whats going on? If it was putting out 100 watts peak, it should blow my JBLs to the moon. I am really disappointed; I can still return it to Crutchfield.com. It was $300; will a $300 or $400 stereo receiver give me the power I need? What should I do? I want something that will give me a lot of power for the future. I am going to be upgrading to some Klipsch bookshelf speakers eventually. I know they are very sensitive and the receiver could drive them, but I am not going to buy my speakers around a receiver that I can still return to the store. Please give me some advice, I really need some guidance. I dont have the cash for separates and I dont feel comfortable buying gear off e-bay. Will a stereo receiver suffice? Thanks for the help, Kenneth. Quote Link to comment Share on other sites More sharing options...
justin_tx_16 Posted December 23, 2001 Share Posted December 23, 2001 what is the wattage rated at? is it like RMS or something rediculous like the PPMO, sense you said its peak is 100 watts, what is its continuous? i personally hate sony stuff like that, ONKYO, Denon, Yamaha etc... just don't care for SONY receivers... ------------------ -justin I am an amateur, if it is professional; ProMedia help you want email Amy or call her @ 1-888-554-5665 Klipsch Home Audio help you want, email support@klipsch.com or call @ 1-800-KLIPSCH RA# Fax Number=317-860-9140 / Parts Department Fax Number=317-860-9150 Quote Link to comment Share on other sites More sharing options...
Manuel Delaflor Posted December 23, 2001 Share Posted December 23, 2001 Are you sure the settings in the Sony are ok? I mean, some receivers can modify the gain and so on... Of course, you will be much better with a real amp Quote Link to comment Share on other sites More sharing options...
Audio Flynn Posted December 23, 2001 Share Posted December 23, 2001 Sorry about your disappointment. I modified my system from 2 channel to entry level HT 3 years a go and really did not like the Kenwood HT receiver "guts". I now have a Sherwood Newcastle 5 x 125 power amp that weighs 70 pounds; the performance really cannot be compared. Quote Link to comment Share on other sites More sharing options...
Klipsch-daddy Posted December 24, 2001 Share Posted December 24, 2001 kenratboy, you must have something wrong. I had the same receiver 1 year ago and it was on a set of klipsch ksb 3.1 and it rocked. Check all of your settings. Plus the Jbl's are kind of low at 88db. ------------------ My HTS: MAINS: RF-3's CENTER: KSC-C1(LOOKING FOR A RC-3 OR RC-3II) SUB: KSW-12 TV: TOSHIBA THEATER VIEW 50" RECEIVER:** Yamaha Rx-v1000 ** DVD: SONY S-360 DVD PLAYER CD: 5 Disc Yamaha comming soon. monster cable interconnects/12 gauge speaker wire Quote Link to comment Share on other sites More sharing options...
matthew2 Posted December 24, 2001 Share Posted December 24, 2001 sorry about the sony, kenratboy. It's funny, exept for a little more hiss, my sony minisystem performs better then all the sony recievers I'v herd, and it's rated at 80W RMS. Weird hey? Weirder is, at 8 OHM load, the sony you baught was rated by consumer reports to put out 131W of power. It may not be clean, but it should be loud on your JBL's. I'm guessing it's something to do with the settings on your reciever. It "should" be pretty loud. What were you useing before to drive your speakers? ------------------ Matthew Gatta' love klipsch This message has been edited by matthew2 on 12-25-2001 at 03:28 PM Quote Link to comment Share on other sites More sharing options...
Colin Posted December 24, 2001 Share Posted December 24, 2001 something doesn't sound right to me - I had a Sony reciever here recently and a pair of small Infinity 2000 RS bookshelf speakers, with 6 1/2" mid-range clothe woofers and one inch clothe tweeters. I measured them with my flea powered Paramours. My Dynaco tube pre-amp dial supposedly approximates actual power use better than typical receivers (where 10:00 on the dial may be about ½ of the amp power available). On mine 9:00 should approximate 1/4 of the power use. I am using a pair of upgraded Bottlehead Paramour mono block 2A3 tube amps, rated at 3.5 watts at 5% THD. listen most of the time at 9:00 on the dial. At the same level, the darling little Infinities average 67 dB at 1 kHz. Yours should be louder than taht. If JBLs were average efficiency (rated at 85 dB/w/m, for example), they probably need about .0312 watts. for in room listening at 9 feet away. 15 dB peaks above the average listening level will require 1 watt, while momentary musical will need only 16 watts. Only microsecond 103 dB peaks at loud volume will require an estimated 128 watts. So you should be getting real world results that aproximate that. How do you get to the 95 dB estimate - comparing it to a live concert? The Infinities do handle high volumes well; certainly able to gobble up anything the Paramours could throw at them. At 11:00 on my pre-amp dial, they play in the mid-80s with music peaks in the 90 dBs. Although the little Infinities sound good, but not great, with low level music and cable movies, I think they sound bland and lifeless with music. They are a poor match for the 2A3 Paramours, even at low to moderate volumes. You are always tempted to turn them up - to get more out of them. They sound better, in fact, with the solid state Sony STR-AV720 receiver that accompanies them. ------------------ Colin's Music System Cornwall 1s & Klipsch subs; lights out & tubes glowing!

jdm56 Posted December 25, 2001 Share Posted December 25, 2001 krb, either something is not set right, or you've got some kind of malfarction. double-check your settings and if it still won't crank, send it back to the good folks at crutchfield for a replacement. sony makes good gear. sure, it's mass-market, but you can't expect krell build quality at "popular" prices. if the sony has the features you want, i'd stay with it. nobody bat's a thousand. good luck and merry Christmas! ------------------ JDMcCall Quote Link to comment Share on other sites More sharing options...
kenratboy Posted December 25, 2001 Author Share Posted December 25, 2001 PROBLEM FIXED, THANKS!!! As William F. Gil McDermott recommended, I tried FM radio as my source. I had a CD playing; the receivers volume was at about half, and not loud. Then, I switched to FM and, well, LOUD wouldnt describe it. After looking at my connections for a minuet, I realized that my CD out put cable was plugged into MY TAPE LOOP OUTPUT! YES, the OUTPUT jacks on the tape loop! I switched them to CD IN, turned the CD back on and all was well. The volume a third of the way up was equal to all the way up before the switch. I am really embarrassed; I have my equipment on a shelf that is hard to work on, so I couldnt see as well. Problem solved, I am going to keep it and I am very happy with it. I was about ready to drive from Reno, Nevada to San Francisco (250 miles) to buy a NAD C370. Now that the Sony works, I will probably hold out and get some separates in a few years. Again, I love the Klipsch forum; you are all so helpful and nice. Thanks again!!! Kenneth. Quote Link to comment Share on other sites More sharing options...
TheEAR Posted December 29, 2001 Share Posted December 29, 2001 Colin, "flea powered Paramours" Yeah you sure like your flea amps.Get a real amp a Krell FPB600 and feel your Klipsch come alive so alive you'll wake up and see the light. The one watt amps are for headphones. Who cares if you will only use the first watt most of the time,you will know if anybody makes you mad you can show them who is boss and use plenty more. Tube amps are colored,big gutsy SS are accurate and say it like it is. At least get a Bryston 14B-ST. TheEAR(s) Now theears Quote Link to comment Share on other sites More sharing options...
