Onkyo TX-SR805 Introduction

DSC02614.JPGAs both a former Onkyo owner and as a recent inductee into the early adopter club of HD optical disc formats, the arrival of Onkyo’s newest receivers, with not only the latest HD video capability but also native HD audio capability, piqued my interest. First on the scene, Onkyo has released five receivers, the TX-SR605, TX-SR705, TX-SR805, TX-SR875, and the TX-NR905 all of which support the latest lossless HD audio codecs, namely Dolby TrueHD (DTHD) and DTS Master Audio (DTS MA), in addition to the latest digital video support through HDMI 1.3a.

Looking at the feature sets available on the TX-SR605 and the TX-SR805 while considering the price, the new Onkyo models are definitely attention getters. The spec sheet alone puts this receiver far out in front of the competition at this price point.

Onkyo has long had a reputation for building good quality audio gear and as being an excellent choice, along with the likes of Denon and Yamaha, for components to step up from basic, entry level gear. My first personal introduction to Onkyo was a college roommate, freshman year, who had an Onkyo receiver that showed to limits of my mid-fi receiver. Budding Audiophile that I was, I one upped him with an even bigger Denon integrated amplifier. While I had higher power in the more expensive integrated amplifier, it was clear that the two pieces were in the same class, unlike the receiver I had replaced.

Remembering that first introduction, Onkyo was on my list as I began developing a home theater and at that time, I felt Onkyo edged out Denon when I looked at both for value. My experiences with the TX-SR602, predecessor to the current TX-SR605, had all been positive and provided support for my impression of Onkyo. Now with the TX-SR-805 in my hands, I can see it this is a continuing trend.

Just wanted to thank those people who recommended the fan combination below (in this thread).

Me and a friend both own TX-SR805, and this fan made a huge difference on our receivers. Receivers run cool and the fans are nearly silent at 9V (voltage is adjustable between 6 and 12V - could be 4.5v on the lower limit, have to check that).

Run a full set of the Sonus Faber Minima Amator @ 90dbs for a few minutes
4 ohm with 1 ohm dips, 82bd 1w 1m, but sound fantastic

Thanks for the tip, I'll check who carry them near the area where I live..

If I can get get my hands on these, that should take care of my strange behaviour lately.

I've been acting very strange recently, and it is related directly to my Onkyo TX-SR805,
which is putting out less heat than usual! (About a couple degrees less.)
So I'm worry about the coming of next winter. Will it affect my heating bills in the upward direction?
I'm really counting on my 805 to keep me warm comes winter, and to save me the most possible on my my heating bills.

Anyone with a solution? That would be very appreciated.



P.S. By the way, I did remove the two internal fans, but it did not raise the temperature!
