The LSA HyperDrive 2 is a state of the art, from-the-ground-up, new design by the talented team of engineers and designers at LSA.
The first review is a rave from Tone Audio who summed with:

"An outstanding value proposition"

"In a world populated more and more by stuff barely anyone can afford, it’s refreshing to see a product so dedicated in offering so much performance for the dollar. In my day we had our Hafler, NAD, and a few others to get us into it all. Sure, they didn’t have the same quality of casework as maybe a Levinson or Krell piece, but the sonic fundamentals were there in enough abundance to get us to all abandon our mid fi receivers."

"Today, the LSA Hyperdrive will convince you it’s time to step up from a Sonos or powered speaker thing and get a real hifi system. Pair it up with a few carefully chosen components and you’ll be thrilled, whether you approach it as a headphone amplifier first or as a 2-channel preamplifier that’s the cornerstone of your system. Very highly recommended. You’ll be seeing this one again before the end of the year."

The LSA HD-2 Preamp/headphone amplifier is a hybrid tube preamplifier combined with a solid-state headphone amplifier that provides up to 2W of power into 32ohm headphones. 

We have not heard a preamp near its $999.00 retail as good.
A great deal at only $699.00
package it with our 150wpc Warp-1 amp
for only $1699.00

It has state of the art microprocessor controlled operation for graceful warmup of the tube circuitry, pop-free startup and shutdown, gain select, output mute, and the push button switching between 3 RCA audio inputs. It features 2 sets of audio outputs to drive an amp and even a subwoofer or two.
A solid state relay (SRR) is used to provide DC output protection for your sensitive headphones and adds no distortion to the signal and will never wear out, unlike a mechanical relay. 
The input stage utilizes a pair of E88CC tubes operating in the ultra-linear range as a Class A cathode follower buffer with a tube-based constant current source (CCS) to provide a natural sounding preamp to drive the solid state headphone stage. (HINT-Ask us about an upgraded set of NOS tubes at time of purchase)
The output driver stage of the HyperDrive-2 utilizes the class leading TPA6120A2 monolithic headphone power amplifier from Texas Instruments to cleanly and solidly drive almost any headphone. This buffer/driver topology gives the HyperDrive-2 headphone amplifier a clear and non-fatiguing SE Class A harmonic profile, while maintaining a low level of total harmonic distortion in the 0.005% range at average to loud volumes with most headphones. 
Three gain settings (0/6/12dB) are selectable from a toggle switch on the front panel to allow the HyperDrive-2 to be matched to any source or headphone with the proper signal levels.  The preamp outputs use the best-in-class Texas Instruments OPA1656 opamps to provide a clear and musically dynamic output when used as a stereo preamplifier. 
The power electronics are provided by a custom designed DC-DC switching circuitry for the 90v B+ voltage and 6.3v filament voltage.  A high quality and convenient universal input 60w desktop style external power supply provides the power for the HyperDrive-2.   
The output impedance of the HyperDrive-2 headphone amplifier is 13 ohms. 
Volume control is provided by smooth turning Alps pot and all opamps utilized are class leading TI OPA1656/1642 for the best combination of transparent sound and musicality.  A simple toggle switch selects between three different gain settings of 0dB/6dB/12dB through a relay There is also a convenient push button microprocessor controlled mute function effected through use of low distortion solid state relays (SSR) which are also used for DC output protection to prevent damage to headphones resulting from an output stage or power supply anomaly. 
The HD2 is capable of driving 2w into 32ohms, thus capable of being paired with the most demanding low sensitivity headphones. The SET tube buffer provides for a beautiful SE Class A harmonic profile that is second harmonic dominant with monotonically descending higher orders with an overall THD of 0.002% at 500mW into 32ohms.
A handsome and heavy CNC machined aluminum chassis with a velvety and durable powder coated finish that expresses the amplifiers sense of speed and power, yet with a reserved elegance.
