All 3 models are shipping. The HyperDrive 2 amp at $999.00 is now shipping and the HyperDrive 5 at $1,499.00 by end of the second quarter 2023. Info info on the Hypedrive 2 preamp/amp is in the LSA preamps and LSA headphone amp sections.
Info on our new state of the art HP-Diamond is now posted. Here is the first photo and info:
The new top of the line HP-Diamond uses an all new driver with aluminum instead of steel. This makes the headphones lighter, and because aluminum is not a magnetic-transferring material, the sound is more open and detailed in comparison with the steel driver used in the highly reviewed HP-1.
The first review in headphone.guru said:
"Listening since 1979 to high-end gear and thousands of headphones the Diamond is one of the best designs for comfort and inner detail I have experienced."
"Sound reproduction was explosive and dynamic. The Diamond had nailed the midrange and the treble and bass were outstanding. The transducer’s ability to extract detail was exceptional."
"Musicality and transparency are what I look for in a top-tier headphone and the Diamond nailed it, never making me feel I was missing anything. Big thumbs up and highly recommended."Read the entire first review at: https://headphone.guru/lsa-diamond-headphone-review-revelation-in-detail-musicality/

Here are two of our favorite quotes from the review:
"It is one of the best headphones I have heard at any price."
"It is just outrageously good in my opinion"
Here is an HP-1 video comparison with the $3000.00 Meze Empryean's
Discovery Hyperdrive 5- A 5 watts per channel class A hybrid headphone amp with exceptional discrete preamp combination. It uses a ultra quiet 6DJ8 (6922) based tube front end with solid state output stage. Both balanced and 6.3mm headphone jacks. Expected ship date is by the end of 2nd quarter 2023 at $1,499.00
Hyperdrive 2 rendering
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.
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 pushbutton 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.
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 XX 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.
