The only reason it isn't rated higher is due to Audiogon's standard of having a perfect front face plate. The only small imperfections happen to be on the face and can be seen in one of the pictures. It came from a good home and was enjoyed by a true music lover in a smoke free environment. Pictured remote is included. The new Cary Audio Design SLP 03 preamplifier is a blend of digital computer technology and pure vacuum tube, analog discrete circuitry.
The SLP 03 consists of actually four 4 analog, 16 dB, and line gain stages. Two separate gain stages are used for each of the two channels. Two stages for each channel equal the four active line circuits. All audio path signals are amplified through 12AU7 vacuum tubes in a class A zero feedback circuit.
The front panel display is a Noritake vacuum florescent display with a blue lens in front. The Motorola processor is the controller for all functions of the preamplifier. Back to the analog side of things, there are a total of eight 8 fully regulated power supplies in the SLP 03 preamplifier. To power the fully regulated power supplies the SLP 03 has two individual R-Core shielded power transformers. Dual power transformers, along with separate left and right supplies, make the SLP 03 a true dual mono preamplifier.
In fact, the channel separation is in excess of 80 dB. This amount of channel independence is a major engineering design breakthrough in vacuum tune designs.
A word about cinema-bypass is in order. We have discovered with previous Cary Audio preamplifier designs, when incorporating the cinema bypass that on occasion the user would forget that the system surround processor inputting to the preamp could be a very high level.
Thus when the preamplifier power switch is placed in the off position, the default would be a feed through of the processor signal and could blast the left and right channel loudspeakers. In the SLP 03 the cinema-bypass only functions when the SLP 03 is powered up with the volume gain setting set at number 47 on the display.
The reading of 47 is unity gain. It might be noted in the SLP 03 one could have a single ended RCA processor input and through the SLP 03 have a balanced output to the left and right channel amplifiers.
Operating the dual 12AU7 vacuum tubes in a current source configuration, true balanced output is achieved with both single-ended RCA inputs or the balanced XLR input selection.

I'm an analog guy. I don't try to hide it and most of you know it anyway. Even so, the LP collection has been heavily pruned while the CD collection just sort of sits there.
I work quite hard on my LP collection, organizing, upgrading individual records, adding new and used …and listening. CDs, well, they just sort of grow roots. I can't say I don't buy new ones; that would be a lie. I buy anything if it seems like I'll enjoy it …but I rarely do that. I have a few favorites and I return to them often. The others I look at, but as for repeated listening, few get played much after a few listening sessions.
So what does this have to do with a review about a preamp? Well, the Cary SLP has no phonostage; which is not at all unusual these days, but I'm used to a full function preamp …one that has a phonostage. I have played with the idea of getting a separate phono preamp, but you're talking to a guy who began this audio journey riding upon a Marantz integrated amplifier …not separates.
Nevertheless, separates were what everyone wanted back in those days when Tyrannosaurus was king. I wanted separates too, but LP was running the audio world back then with reel-to-reel and high-end tuners being a rather distant second—at least in my world. So, all preamplifiers had a phonostage and that was the way it was! My Marantz integrated had a damned good phonostage.
These are marked the usual CD, etc. This is a preamp for folks who are seriously into many different types of entertainment! The IEC connector separates the right and left connections; the power cord's in the center …incredible. I've fought with far too many pieces of equipment that, having the power cord on one side or the other, made it impossible to keep wires separated from one another. Ingenious There is no problem with stiff interconnects with this baby—manufacturers should have done this years ago!
The Cary sure was a lot easier to use than my Anthem. Even so, the remote control is far too tiny for a man with poor eyesight Rats, I need glasses again? It is, however, easy to use. Choosing the input is simple and setting volume control and balance is even easier. There is a mute switch, which is easy to find - as opposed to what one finds on more and more remotes.
With my TV remote, I have to frantically search for mute when a commercial that embarrasses me is shown on TV. I can't believe a member of the same species as me can make a commercial that is far more stupid than an inbred poodle.
Maybe it's inbred poodles making the commercials; that would explain a myriad of things. The remote also has functions for the Cary CD players.Normally, I try to avoid dragging readers through the problems I have in obtaining equipment and making it function.
In this case, however, I would do a distinct disservice to any audiophile looking for a great tube amp with truly musical sound, and to any audiophile who already has a Cary CAD S and has problems with it. Both worked very well, but I needed two things: More power than most audiophiles need, since a reviewer never can predict the sensitivity of the speakers that come in for review, and balanced inputs for compatibility with the wide range of equipment coming through my listening room.
It provides 60 watts per channel in triode mode and watts per channel in ultralinear mode into an 8-ohm speaker load. It also had good specs by tube standards in many other respects. These are described in detail in the specifications listings at the end of this review.
Considering a tubed preamp...
It also had a soft-start turn-on circuit to extend tube life, and backlit front-panel meters to show the circuit bias setting for each channel and whether it was operating correctly.
Specs are one thing, however, and reality is another. I quickly found I had serious problems with the review sample, and largely because of gain. While the Cary S seemed to be advertised as an amplifier that could be used with the normal range of preamps, the truth turned out to be very different. The amplifier simply did not have the gain to work with either my Pass or Quad preamps. It had been a long, long time since I had encountered gain mismatch as a problem, and the specs for the S did not tell me enough to suggest the cause.
Once again, the specs were impressive. The SLP is not an exercise in audio minimalism. All audio path signals are amplified through 12AU7 vacuum tubes in a Class A zero-feedback circuit.
Its circuit is a fully balanced design with four analog gain stages: Two separate gain stages are used for each of the two channels. One gain stage amplifies the positive phase and the other gain stage amplifies the negative phase. The two stages for each channel represent the four active line circuits. It also has eight fully regulated power supplies with separate supplies for each channel's analog circuit along with power supplies for the display and dual supplies for the Motorola processor.
The SLP has a fully functional remote control, and a far wider range of inputs and outputs than many competing tube preamps. There are wide range of other features like a tape monitor loop, cinema bypass, an RS full remote configuration interface, and power-amplifier triggers.
Cary SLP-03 Balanced Stereo Vacuum Tube Preamplifier [Expired]
Unlike far too many newer tube preamps, it also had a balance control—a feature I find essential in getting the best imaging out of a given recording and that leads me to reject any design that lacks a balance control. In short, I was right back where I started.
I supposed I should have caught the gain problem earlier, but I now got far more serious about finding out what was happening, and read enough user comments on the Internet to see that others were having somewhat similar sound problems. Accordingly, I got far more proactive in contacting Billy Wright at Cary, and it became clear that the CADS simply was not designed for general use.
