Rotel's new nearly-all-in-one audio component sounds very sweet
could call it an "unreceiver." Or maybe a "deceiver."
refer to it, Rotel's RAP-1580
is a one box solution to most current audio needs. The only mainstream feature
it doesn't have on it is a radio tuner, which would make it a
"receiver." And as popular as receivers are, I can't see why many
folks would care about that in 2017, since the RAP has Bluetooth capability by
which you can stream your favourite radio stations from around the world via a
smart device and the Internet.
is more a traditional "integrated amp" - a beast that combines
preamp/processor and amplifier into a single box. Purists prefer these
components to be separate, and there are good reasons for this, but in my time using
the Rotel in my home theatre so far its exquisite sound quality has pleased me
I didn't think
it would. I've been running separates for years - mostly from Rotel because I'm
a fan of their performance/price quotient - and the least power I've had on tap
is 200 watts per channel (and usually it was 500 watts). My angst came from
this new Rotel only being rated at what I assumed would be a nice but
inadequate for my room 100 watts per channel (into 8 ohms).
Once the RAP-1580's
substantial heft (it's just over 50 pounds) was in place and hooked up I fired
it up - nervous that I'd have to crank it all the way to 11 (hat tip to Spinal
Tap) in order to get the volume I want. I like it LOUD, to reproduce not only
the sound quality but the volume of the original recordings as well. I can only
do it when my wife is out, unfortunately.
I needn't have
worried. When driving my JBL
ES seriesspeakers, after the system was calibrated to the best of my ability
using a sound pressure level meter and a tape measure - with a friend to hold
one end of the tape - I never had to exceed the volume setting I use usually
with Rotel equipment. Indeed, the 100 Class A/B watts per channel (which morphs
to 150 watts for stereo only) is not only more than adequate, it is superb. I
pumped all different types of music through it - well, no hip hop - as well as
a wide variety of video sources (from DVD to UHD) and have fallen completely
under the spell of this wonderful piece of equipment.
isn't perfect. In fact, I've read some online comments from people who are really
disappointed in it for one reason or another - most of which have to do with
its lack of automatic room correction (a handy method by which the component balances
itself and your speakers on its own), or the fact that it "only" has
seven channels of amplification built in, or that it has handshaking issues
The Rotel does
include 10 channel Parametric Equalization to help you in optimizing your
room's acoustics but the adjustments can be quite tedious and intimidating, especially
if you don't really know what you're doing. This is undoubtedly why many people
would rather just set up a microphone and press a button and let the equipment
do the job itself. I can see that; maybe Rotel will include that next time.
initial balancing was set up I didn't find the need to tweak the PE in my
listening room anyway, so that particular issue didn't bother me a lot.
I had some
other issues, though, including some major handshaking delays - of several
seconds, sometimes - when switching HDMI sources. These delays could be issues
if I used HDMI for audio more than I do, but in my setup I'm more interested in
the Rotel amp than its processor and the company has built the RAP-1580 to take
care of my needs very well.
because, other than testing the various input/switching/processing features
offered by the RAP (and there are plenty of them) I generally feed the Rotel's
analogue inputs directly from the analogue outputs of the source unit, which in
this case is OPPO Digital's
UDP-205universal player (whose review is coming in a couple of weeks). Connecting
the components that way uses the source device's processing and basically
passes the analogue signal right through the RAP's preamp section, bypassing
everything but the volume control, and to the amplifiers (where they belong!).
can do this - you need a player with analogue outputs and internal processing
that's at least as good as the pre/pro's - but if you can swing it, it is, in
my never humble opinion, the best way to listen.
On the other
hand, it isn't as if the RAP-1580's processor doesn't have the state-of-the-art
features built in. Heck, it's more up to date than I am! I haven't even
progressed from 5.1 to 7.1, let alone adding ceiling and other speakers. I
probably won't, too, unless the Lotto Gods smile on me and I build a new home
theatre from scratch. It's just not worth the hassle.
But if you
have the capability the Rotel will reward you with Dolby Atmos and DTS:X
processing - though you'll need to add extra amplification to get all of the
can't comment about the RAP-1580's performance other than in 5.1, but I have a
feeling that puts me smack in the mainstream of home theatre enthusiasts who
love good quality audio but don't have the room, the budget, or the inclination
to add all the extra channels.
boasts a total of eight HDMI inputs, with 4K pass-through (you don't even need
the RAP turned on to watch something hooked into it via HDMI). Three of the
HDMI inputs and both HDMI outputs support HDCP 2.2 (yet another darn copy
protection scheme) as well.
I'm no authority
on copy protection stuff, but I believe it's behind the handshaking problems - where
one component has issues connecting with another - that I first noticed with
HDMI. It made me wonder if the new 2.2 standard is behind the seemingly
interminable pauses between switching sources and actually getting sound.
reason to run analogue…
multi-channel analogue inputs, Rotel also includes inputs for a CD player,
balanced XLR cables, a tuner, and there's an AUX analog input as well. It also
offers PC-USB input supporting 24-bit 192kHz audio, Bluetooth aptX and there's even
an input for a moving magnet-equipped turntable. You even get rack mount ears.
If you can't
run analogue, the Rotel comes with six Wolfson premium 24-bit/192kHz Digital to
Analog Converters to do the job for you. And they do it fine.
front panel is dominated by a seven-inch LCD on the front panel, and its type is
large enough that I can read the volume, source and other info from across the
listening room, without having to put on my glasses (a first!). The screen should
have allowed me to tweak the RAP's audio and video stuff without having to turn
on the television to which it's connected, except that the configuration menus'
text is still too small for me to read from afar. Fortunately, you can also
access the menus via the television, though the text itself looking like it was
ripped off from an old DOS computer.
A bigger deal
for me was the error message "Invalid format" that I got when I tried
to access the menus via my 1080p Plasma TV. As it turned out, however, it was the
aging TV that proved invalid and once I swapped it out for my Panasonic 4K TV
thatparticular problem went away. Whew!
another one reared its ugly head: while the Rotel does, indeed, pass 4K signals,
it wouldn't pass HDR, so I had to patch the OPPO directly into the Panasonic
instead of routing it through the RAP-1580. Rotel said the RAP does do HDR, so I
think this, too, may have been an issue with the TV itself. The same thing
happens with my Roku Ultra, even when it's patched into the TV directly.
words, it's always something.
completely honest, I'm more interested in the Rotel for its pure audio performance
than any kind of video gymnastics anyway; in my setup, the OPPO handles as many
sources as possible (including the Roku's) so nearly everything I could want to
play goes to the Rotel via its analogue audio connections. And as luck or good
design would have it, the RAP-1580 performs superbly in this task.
SACDs, DVD-A's, Blu-rays, 4K UHD discs, CD's, digital files - you name it, and
the RAP-1580 did an excellent job with any good signal. The sound is sweet and
pure - and as loud as you want it - whether you're running stereo audio or the
latest surround movies (with the caveat that I didn't try anything beyond 5.1).
testing, I like to use Opus 3's CD "Test Record 3: Dynamics," which
includes meticulously analogue recording ranging from the solo human voice to a
jazz combo to a church organ, the latter of which is a really good way to test
a system's mettle. The Rotel ate it up and spat it back through the JBL's
beautifully, with no distortion or colouration I could discern. Oh, the
neighbours weren't happy, but that's a feature, not a bug.
the only stereo source, of course. The Who's Magic Bus from the remastered Live
at Leeds is another great test of a system - the pure power of the recording
comes through beautifully even though it was made live back in 1971. I played other
classic rock, as well as classical, big band, show tunes, you name it, and I
loved the sound that came from the two speakers.
Then I went to
surround. If you're of a certain age and musical bent, you haven't lived until
you hear the DVD-A of "Brain Salad Surgery" on a system like this. As
happens with newer and better equipment, I heard nuances in there that I'd
never heard before, despite having owned various versions of the album since it
first escaped the recording studio.
I also love
Dire Straits' Brothers in Arms, especially in the 5.1 of its DVD-A version. It
was recorded digitally, though the original vinyl and CD versions sounded kind
of thin. The DVD-A is anything but thin, however, so if you want to learn if
your system is up to snuff I'd suggest you try playing "The Man's Too
Strong" as loud as you can take it. It sounded great via the RAP-1580.
A bunch of
concerts with high quality sound were also on tap, including the Cream Reunion
and Ray Charles at Montreux. These are available in stereo or surround but I
loved the room-filling 5.1 versions the most because they put you right in the
audience. Not surprisingly, the Rotel facilitated this very nicely. Channel
separation is excellent and the soundstage, even in stereo, is wide and deep.
included the Technics
Tracks version of The Who's Quadrophenia, the best digital version of
"Townshend's Last Masterpiece" I've heard to date. Want Keith Moon's
drums to thunder like they did on the original vinyl version? This is the one
for you - and the Rotel was right there egging Mooney and the lads on.
listening to this component so much that even after using it a couple of months
I'm still finding excuses to spend more quality time in the home theatre than I
should, considering all the review cars I'm supposed to be driving.
It's been a
long time since I've been this excited about a "mere" 100 watts, but
I should have remembered that Rotel, if anything, is conservative about its
specifications. Speaking of which, here are a few other specs I ripped off from
20Hz - 20kHz ±1dB
10Hz - 100kHz ±1dB
Inputs: 20Hz - 20kHz ±0.5dB
Ratio (IHF "A" Weighted)
I did have one
other issue: Twice, the Rotel's front panel LCD came up all white when I fired
it up. It was quite disconcerting, and required a hard reboot (shutting it down
via the rear panel switch, then restarting) to fix. The reboot worked fine both
Despite my misplaced
angst over the power output, the RAP-1580's sound quality won me over completely
- not that I'm surprised, considering my experience with Rotel stuff over the
years. I hope they can address the issues I and others have found (firmware
updates, perhaps?), and I assume they will.
If you check
out online owners' groups and places like that, you'll notice some people opining
that the $3800USD RAP-1580 is overpriced for a unit that doesn't come with room
correction and other stuff many people think is important in 2017. They may
have a point, at least when it comes to the features that Rotel - a smaller
company that has to balance wishes with possibilities - has chosen to leave out
of this unit.
On the other
hand, in my never humble opinion, the RAP it's priced fairly. Heck, I've paid
more than the RAP's retail price for amplifiers alone, and the RAP-1580's sound
quality is at least as good as they were, and its power is all I could want in
that room, with those speakers. So whether or not the RAP is overpriced is a
matter of perspective.
So if you're
looking for exquisite sound quality and can't afford or don't want separates,
you should definitely take a look - nay, a listen - at this Rotel
If only they'd
pry it apart and make it available as separates!
