I used the Integra DTR-50.1 with primarily two different sets of speakers – the Canton GLE 470 system and the Klipsch Icon WB-14 system. The Cantons are rated 4 ohms nominal. The Klipsch speakers have a main driver with an impedance dip which demands a little more current from an amp than the speakers' highish sensitivity ratings would imply. I left the DTR-50.1 set for 8 ohms throughout the review period and never really reached the receiver's practical output limit. I had up to 7 satellites in action at any given time. Nevertheless, the DTR-50.1 was capable of producing adequate current to safely drive these different speakers.
My budget reference receiver is an Onkyo TX-SR805. This receiver can tend towards brightness with certain material. So I was concerned that the DTR-50.1 may suffer the same tendency. I am pleased to report that the Integra receiver never came through with a bright edge. In fact, the DTR-50.1 had a special harmonic richness to its sound. I even likened the effect to somebody pouring maple syrup on my head. Even though its sound was harmonically rich, the DTR-50.1 was still open and transparent sounding.
I am writing this review after having put my reference Onkyo receiver back into the system. The Onkyo simply switches HDMI. It does not deinterlace or scale the signal. Right now, I am really missing the Integra receiver for its video prowess. It was great at deinterlacing DirecTV signals. And it more cleanly switches the pristine signal from my Oppo BDP-83 Blu-Ray player. The subjective difference between the two receivers is not subtle and I much prefer the Integra with respect to its handling of HDMI video signals.
The DTR-50.1 reproduced Hilary Hahn's violin with almost no electronic haze on her 1999 CD release of Beethoven Violin Concerto and Bernstein Serenade. Thanks to Audyssey Dynamic EQ, the Hahn CD had substantial presence at every volume setting which really helped me hear all the natural harmonics from Ms. Hahn's instrument.
In the Pixar movie Up, Michael Giacchino score was reproduced with great delicacy. Voice reproduction was very transparent through the DTR-50.1. This receiver produced fine bass weight on this movie.
This receiver cleanly passed along all the sonic complexity contained within the Blu-Ray of Jeff Beck: Performing This Week - Live at Ronnie Scott's. The DTR-50.1 preserved the natural timbre of instruments on this disc and the bass was extremely tuneful. In my listening notes, I wrote that the music took on a fiery intensity through the Integra. There was also a very seductive presence in the midrange, particularly with the few tracks on this disk which feature vocals.
The Integra created a nice surround bubble on Star Trek. I watched this movie on the Klipsch Icon W system at reference levels. The more majestic sound effects were reproduced with great intensity. This movie played through the Integra DTR-50.1 reminds me why I'm so in to Home Theater!
There Will Be Blood has a generally sparse soundtrack that is interspersed with various loud effects-filled scenes. During the sparse scenes, the background orchestral music involved a lot of minor chords. I liked the way the DTR-50.1 passed along the creepy, discordant emotions in this music. This receiver was capable of wide dynamics and the louder scenes were quite impressive. The music in the gusher scene had great clarity in the upper registers and I felt that the DTR-50.1 did a good job of preserving the air in the soundtrack. And Daniel Plainview's voice thundered mightily in the bowling alley scene!
