That HDMI muting issue aside, my time with the RSP-1572 was mostly smooth sailing. It’s impossible to fault the Rotel pre-pro’s basic A/V performance, and its elegant simplicity should harmonize nicely with a certain type of buyer’s system plans. If you’re a performance-first, features-second type who logs as many hours on music playback as on TV and movies, you may very well number among them.
DOLBY DIGITAL PERFORMANCE
All data were obtained from various test DVDs using 16-bit dithered test signals, which set limits on measured distortion and noise performance. Reference input level is –20 dBFS; reference output 200 mV into 100 kohms. Volume setting for reference level was 85. All level trims at zero, except for subwoofer-related tests, all speakers were set to “large,” subwoofer on. All are worst-case figures where applicable.
MULTICHANNEL PERFORMANCE, ANALOG INPUT
Reference input and output level is 200 mV; volume setting for reference output level was 84.5.
STEREO PERFORMANCE, DIGITAL INPUT
Reference level is –20 dBFS for 200 mV output; all level trims at zero. Volume setting for reference level was -85.
BASS-MANAGEMENT PERFORMANCE
Measured results obtained with Dolby Digital test signals.
I saw nothing on the test bench from Rotel’s RSP-1572 to contradict the superb sound I heard from music and movies alike. The pre-pro’s distortion and noise performance were consistently very good. Noise results fell less than a decibel short of the theoretical ideal on the 16-bit digital-signal tests, while analog-input noise improved on this by about 10 dB — good, but not great, performance. S/N for 96/24 PCM stereo signals bettered the 44.1/16 result by about 6 dB, a meaningful gain but also a few decibels shy of the best we’ve seen. Taken together, these suggest that analog-domain noise was the Rotel’s limiting factor, a phenomenon not uncommon among more “audiophile-oriented” designs where factors other than data-sheet specs often influence component selection. In any event, these figures suggest a real dynamic range of something over 100 dB, which, unless you listen in an anechoic chamber or over very fine headphones (and headphone amplification, as the RSP-1572 lacks a “cans” output), is plenty to spare.
One other note concerns the RSP-1572’s crossover-filter action. On digital signals, I found both high- and low-pass sides to show nominally 24-dB-per-octave slopes; the more usual arrangement is for the high-pass side to roll off at 12 dB per octave. With analog inputs, however, both sides displayed nominally 12-dB-per-octave slopes. The difference could conceivably effect a mild shift in bottom-octaves character between the two media, though on my system (which I cross over at a low 60 Hz), I noted no such thing.
I cannot believe this magazine allows a company like Rotel to continue to put out inferior products at a premium price and stoop enough even to review this POC. Can anyone say "advertising"?? I do not own this overpriced inferior performer but even from reading this poorly written article I can say, never will. Dropout problem between audio modes not a big deal. Oh yeah...big deal here guys? Shall I go on?
I agree with Mike Conley, I owned the Rotel for about 2 months it looks great and sounds okay and way overpriced. The farouda Processor is out of date,the picture quality is so Bad, why have a processor at all, Bryston doesn't, and if you do it would be nice to turn it off. And wht not have a setup program? The remote is so inferior to any remote out there, On a $2300 product a $5 remote just doesn't cut it. Rotel has very nice ads in your magazine but come-on man any receiver from Yamaha, Denon, Integra, and Pioneer Elite is far superior at half the price!
To add to my comments above:
I have a Pre Pro twice the features and $800 cheaper. (Integra DHC 40.2) This is one of the reasons for the decline of the mid-high end audio industry. iuliucra is witness to what I say here. I have been an S & V subscriber since late 70s (Stereo Review) and they have declined with the industry. that is unfortunate.
Um, thanks for the input. A few points here:
1) @MikeConley, @iuliucra :Rotel hasn't been a regular advertiser in S+V for years, so any claim that "advertising" influenced the outcome of this review has no factual basis. (And @MikeConley, as a longtime S+V subscriber, you could have easily fact-checked that before taking your cheap shot.)
2) @MikeConley: S+V has no control over what products a company puts out, and it's ludicrous to assert otherwise. It is safe to say, however, that any product that's been offered up for sale is fair game for a review.
3) @MikeConley: "Dropout problem between audio modes not a big deal..." The review cites the HDMI muting issue as being both irritating and a bit of a deal-breaker. Btw, S+V's is the only professional review I know of that calls attention to this issue in the current Rotel series. Scour the other reviews sitting on the Web and you'll see what I mean.
4) @iuliucra: The review is clearly critical of the RSP-1572's remote control. It even states that "any but the cheapest of today’s A/V receivers will outdo it." So what, then, is your point? Oh, right, it's that advertising dollars -- a non-starter argument in this case -- determines the content of our reviews.
Mr Griffen, I've subscribed to Sound & Vision, Home Theater, Absolute Sound & Stereophile mags for many years and one thing I know is advertising in a mag gets you reviews. A friend on mine has a small High End audio company and would to get his equipment reviewed, He approached one of the mags and they told him that he would have to start advertising in their mag. A few years ago Yamaha stopped advertising in Home Theater mag.for whatever reason. Guess what none of their equipment was reviewed during that time. About 2 years ago they started to advertise again in HT and low and behold their equipment is getting reviewed again. So don;t tell advertising dollars determines reviews, I know you can;t agree with me but I know you know it's true.
@iuliucra : Do you really think you're in a position to be lecturing anyone about truth? My response took you to task for saying something that was false: that Rotel "has very nice ads" in S+V. But instead of acknowledging that fact, here you come again making unsubstantiated claims and inferring that I "can't agree with you" because of my position.
What is the name of this "small High End company," and what is the name of your friend who owns it? I look forward to reading your response because it would be the first real bit of information that you've contributed so far to this "discussion."
Great article. Looks like a very nice surround sound system and would make a great fit in your home theater. Having a surround sound system like this one is great and can easily be hooked up with universal remotesthat can give your home theater great value. Thanks for sharing.

I own the 1570, and i find it to be one of the nicest sounding units i have heard ! And i have owned Marantz SR7002, Cambridge 651R and demoed lots of others before i making my next choice... The HDMI drop out is in minimal And not as bad as the Cambridge unit. Tho i did really like the sound of the Cambridge. Hoping to hear the new 751R.
Calling the Rotel overpriced inferior performer, U need your fucking head examined...
(MikeConley) Your an idiot...
Good Review
Think i might upgrade my 1570 to the 1572
I for one am gratified to finally read a review that mentions the muting of audio at the start of every track. Had I known about this before buying it would have been a deal breaker. I bought the 1572 for it's audio performance, which I rather quite like. The utter transparency and dynamic range is fantastic for it's price but listening to music has become so unenjoyable i have simply given up. When I can get the money to replace it, I will
At one time Mike Sheehan at Rotel promised the company was working on a fix. i guess they gave up or lost interest. As have I.
