Rotel Stereo Preamplifier RC-1590

Product: Rotel RC-1590 preamplifier (pre-amp).

 

Functional Description:

 

100% operation in an excellent condition. This pre-amp
(preamplifier) has been flawless.

 

Cosmetic Description:

 

8/10. This unit is cosmetically almost as it was the very first
time that I opened the box. It only has a small chip in the top. I just
realized of it when I cleaned it to take some pictures for this sale. The usage
was around 30-60 minutes 2 or 3 times per week.

 

What is Included:

 

Rotel pre-amp and all the original accessories that come in the original
package. All these accessories were never open (besides the Remote for some
weeks until I configured my Harmony Remote). I used my own cables to
run and operate this device.

Remote with original non used batteries, power cable, USB A to B
cable, Rotel Link Cable, RCA Cable, user manual and all factory boxes and
packaging.

 

Original Price: $1,749 plus tax

 

Modifications: None.

 

Reason for sale: I used this pre-amp together with an
Oddyseyaudio AMP in my Master bedroom. The source was an Oppo 105 for CD using
Analog inputs and a Bluesound Node 2 for streaming services using Coax cable.
Sometimes I used the OPPO as DAC (Bluesound to oppo 105 using digital COAX and
then XLRs from my OPPO to Rotel). The speakers are in Bower and Wilkins In
Ceiling Speakers CCM 7.3

 

I need to say that I like better the sound when I used the RC-1590
as DAC and PREAMP rather than DAC on OPPO and Rotel as pure pre-amp. Sound is
subjective and depends on all the components on your system, so I am just
sharing my experience.

 

I am very pleased with the sound, but I reconfigured my setup
and I had to move the amp to other room and I put a Bluesound Power Node 2 to
simplify my setup in the Master.

From the Manufacturer:

 

The RC-1590 stereo preamplifier has been engineered to the
highest audio performance levels and provides an incredible level of control
and flexibility for the user. Starting with a high-performance power supply
consisting of two Rotel custom built toroidal transformers for maximum
efficiency and low magnetic fields, these transformers provide low-noise
isolation between the analog and digital signals. They are part of a reference
grade power supply consisting of individual analog and digital regulator
circuits with custom-made slit-foil capacitors. Slit-foil capacitors have very
quick charge/discharge times and low signal loss ensuring tight bass
performance.

 

The RC-1590 is fully feature-laden with Balanced XLR and
Unbalanced RCA inputs and outputs, a TI precision volume control IC, a fixed
volume line output, dual mono subwoofer outputs, digital outputs (Coax and
Optical), digital inputs (3 Coax and 3 Optical), Aux, CD, and Tuner analog
inputs, internal aptX Bluetooth (supports aptX and standard Bluetooth) with
rear mounted external antenna, a front USB iPod with 2.1A charging input, and
rear panel PC-USB 24-bit 192kHz input supporting DSD (Windows) and DoP (MAC
computers DSD over PCM).

 

Other essential features include a remote control, 2 x 12-volt
trigger outputs, a dimmable display, an automatic power off function
(configurable), RS232 and IP control for automation system integration,
internet based software updates, Rotel Link connection, a detachable IEC power
cord, an external IR remote input, and a front mounted 3.5mm headphone output
jack.
