Conrad Johnson CT5 Stereo Preamplifier Reviewed

Conrad Johnson CT5 Stereo Preamplifier Reviewed

For half the price of their flagship model, the CT5 delivers much of the same sonics. With its lush midrange and large detailed soundstage, the CT-5 delivers exceptional performance through its single-ended only outputs.

conrad_johnson_ct5.gifConrad Johnson is one of most well-known and respected names in the world of tube audio gear. The CT5 stereo preamplifier reviewed here is the result of trickle-down technology from the company's famous ACT preamplifier, which itself descends from the legendary and far more expensive ART preamplifier. At $8,500, it is roughly half of the price of the current ACT II preamplifier, which shares its composite triode circuit design. The Conrad Johnson website provides more information on this circuit design.

The CT5 is a beautifully designed and wonderfully built preamplifier. It features Conrad Johnson's signature champagne-colored faceplate, divided into three horizontal sections. The left section features a discreet silk screen of "Conrad Johnson" above two metallic buttons, power and source. Adjacent to the source button is a row of five orange LEDs to indicate the selected source. The center section is concave, with horizontal Plexiglas panels that protect the two 6N30P tubes.

The right side of the unit has a circular display window with orange LED numerals displaying the volume for each channel. Buttons below the circle control volume, mute and engagement of the external processor loop. The external processor loop allows for easy integration with a theater system. The back side of this 31-pound, 15.5-inch-deep, 19-inch-wide and five-inch-tall unit features a bevy of high quality single ended inputs and outputs. The CT5 comes with a hefty machined metal remote control.

Turning on the CT5, I was surprised by the long wait for the unit to warm up, during which no control input is accepted. I quickly learned to simply leave the unit on and muted in between a day's listening sessions. Once warmed up, I found the sound quality to be excellent. The CT5 is quite simply one of the best preamplifiers I have heard to date. I have heard the twice as expensive ACTII and, while it is better, it isn't even near twice as good. The midrange is extremely smooth and liquid, without smearing details. Likewise, the highs are extended and clear without any harshness, and the lows are deep, solid and detailed, albeit lacking some of the impact of the best solid state amplifiers.

conrad_johnson_ct5.jpgHigh Points
• The CT5 has a magically lush-sounding midrange, with good overall sonic presence. It doesn't sound soft like some tube preamps often do, yet it is never, ever harsh in the manner of many solid state preamps not at the cutting edge of their designs.
• The soundstage is large and amazingly detailed compared to other tube amps in the neighborhood of the CJ CT5, as well as some of the better solid state preamps.
• The theater loop makes it easy to integrate the CT5 into a theater system. How other audiophile preamps miss this feature is beyond me. Thank God it's on the Conrad Johnson CT5.
• The solid metal remote control feels appropriately beefy for a component in this price range and it gets the simple functionality of the preamp done with style. No Creston touch panel needed here, unless you want one.

Low Points
• The CT5 takes several minutes to warm up, which can seem like an eternity if you are trying to entertain and/or show off the preamp to fellow audiophile guests. Even waiting seven minutes for your background music to play seems extreme.
• The lack of balanced connections will stir up that age-old debate regarding balanced vs. unbalanced connections in an audiophile system. We know where CJ stands, but what about clients who have $6,000 a pair interconnects going to their fully balanced amps? Tell them why they made a bad investment in their systems or simply don't sell them the preamp. At this price, consumers should expect it all.
• As magical as tubes can sound, they need to be maintained and replaced on occasion. Tube lovers know this, but it's important to disclose for first-timers who (I guarantee) will be seduced by the Conrad Johnson sound if they go for an audition of the products.

Conclusion
The CT5 is one of the finest-sounding line stage preamps currently available. The tube circuitry used in this component maximizes the benefits offered by tubes, while minimizing the noise and lack of detail that can accompany tube gear. The CT5, with the exception of the lowest octave or so, easily keeps up with the first class solid state gear's ability to reproduce fine details. What makes the CT5 so special is that it also adds the tube's ability to provide a lush, liquid midrange and high end that is full of presence and devoid of grain. It does all of this in a large soundstage where the performers are not only solidly placed, but they also have air and space around them that brings a sense of realism to the better recordings. If you enjoy tubes and your budget even comes close to affording the CT5, you owe it to yourself to check it out. You just may need to find a way to increase your budget a bit.
