Don't be fooled by what others might have told you about buffer stage preamplifiers. The Segue is an amazing sounding zero gain tube preamplifier that performs well about its price class.

[sey-gwey, seg-wey] to make a transition from one thing to another smoothly and without interruption:

"............the top and mids are smoother and more refined with greater ‘definition’, transparency and air while the bass is also better defined and refined. There was a small improvement in the soundstage as the system already possessed a great one......."

".......I'm so impressed with this buffer that later this summer I'm going to buy one of Bill's top preamps. I've been made a believer in preamps again........ "


For several years our customers have been asking for a preamp version of our very popular Segue tube buffer stage. The Segue Tube buffer found its way into many high end audio systems around the globe. New for the 2018 model, we are releasing the very first Segue pre for those who do not need the high gain of a standard preamp. The Segue pre will be everything the stand alone Segue buffer was but now used as a stand alone preamp compatible with most any amplifier made today including solid state and Class D designs. In keeping with Response Audio tradition, The Segue Pre will utilize the top quality design and components as the original Segue whch now includes a top notch volume control. Because the Segue Pre is designed to be left on for extended periods, it will not be equipped with a Mute switch. The Segue Pre can be left on at all times just like your solid state amplifier.

The results are as follows:

Restores proper frequency balance though better impedance matching due to its very low 90 ohm output impedance.
Improves tone and weight with the use of a 6922 tube
Relaxes and opens up the music for better detail, imaging.
Reduces listener fatigue often associated with digital and solid state components
Enhances the 3D performance

The Segue utilizes a single 6922/6DJ8 dual triode tube and is run at voltages that allow you keep it on at all times. Input impedance is high at 100k ohms with a very low output impedance (a good thing) of only 90 ohms.

HT Bypass - The Segue Preamp uses an active buffered HT Bypass. The input from a preamp/processor still passes through the tube buffer stage allowing your HT system to benefit from the sound and low output impedance of the tube buffer stage.

The power supply utilizes 2 separate high current toroidal transformers. A dedicated transformer for the +/- rails of the B+ supply and a separate, high current transformer for the new regulated DC supply boards feeding the tube filaments. Elna Silmic II capacitors are employed for the power supply filter capacitors with last stage bypassed with high quality film cap. Ultra Fast diodes are used throughout. Clarity Cap output capacitors and  Cryogenically treated Silver Plated/Copper/Teflon signal wire.
The Segue is built into a  brushed aluminum chassis that mathes our new Spirit Linestage models
