Brinkmann Voltaire Integrated Amplifier.
(http://brinkmann-audio.com/main.php?prod=voltaire&lang=en)
"An entirely new design, Voltaire begins as an ultra-performance Integrated Amplifier. Borrowed from our Marconi Mk II Line Preamplifier, Voltaire?s hybrid circuitry utilizes vacuum tube phase inverters for superior voltage tracking. (For Voltaire, Brinkmann has chosen Raytheon military tubes. Developed for rocket guidance systems, their supreme reliability promises decades of trouble-free use.) Signal path lengths and internal wiring have been kept to an absolute minimum. 105 micron-thick copper circuit board traces, Lundahl interstage transformers and zero global negative feedback further demonstrate Voltaire?s uncompromising design and execution."
"The modularity pioneered for Nyquist reaches a higher level of versatility with Voltaire, which can be outfitted with either an MQA compatible, Roon Ready streaming DAC similar to Nyquist Mk II (its decoding hardware is identical to Nyquist Mk II) or a simplified version of Edison Mk II Phono Preamplifier. So equipped, Voltaire becomes a complete audio system occupying a single chassis."
New Garrard 301 Turntable.
(https://garrardturntables.co.uk)
"The Model 301 is finished in high quality Ivory enamel paint finish, meticulously built and combined in a unique package of SME M2-12R precision tonearm and new generation solid walnut isolation plinth. An iconic, elegant turntable delivering audio perfection with modern handcrafted excellence."
Living Voice LVCD CD Player.
"This red book CD player is based on an OEM chassis from Canary Audio that Living Voice make significant upgrades to including an ECC88 tube on the output, a huge power supply for high and filament voltages and some ?very posh parts?, price is ?15,000."
Accuphase A-48 Class A Power Amplifier.
(http://www.accuphase.com/pdf/a-48_e.pdf)
"The power amplification stage employs a 6-parallel push-pull arrangement of power MOS-FETs mounted directly to large heat sinks for highly efficient thermal dissipation. The result is fully linear power progression of 45 watts into 8 ohms, 90 watts into 4 ohms, 180 watts into 2 ohms, and 360 watts into 1 ohm (music signals)."
Sonnet Morpheus DAC.
(https://www.sonnet-audio.com/Morpheus.html)
The new DAC from the ex-founder of Metrum Acoustics.
"The SDA-2, a new generation DAC module was designed to get the best regulation possible. The result of this process is an extremely high linearity, right down to -140 dB, which gives our products a realistic 24 bit dynamic range. It is musical, honors the Non-oversampling principle and simultaneously incorporating the technological progress that has been made over the years."
Pass Labs Int-25 Integrated Amplifier.
(https://www.passlabs.com/amplifier/int-25)
"A smaller stereo Class A amplifier at a lower price, it takes advantage of the lower power requirements to have simpler single-ended circuitry and fewer parts in the signal path. This also allows elimination of degeneration, ?that other negative feedback? in all stages.
Simpler and fewer gain stages improves speed and stability. Lower voltages means the ability to run gain devices at higher bias currents, more deeply into Class A. Newer power Fet technology replaces banks of parallel small transistors with a single pair of industrial devices, each having a 700 watt / 40 amp rating."

NuPrime AMG Series
(https://nuprimeaudio.com/product/amg-pre/?v=68caa8201064)
(https://nuprimeaudio.com/product/amg-sta/?v=68caa8201064)
"The layout of the AMG-PRE takes excellent care in isolating the sensitive audio signals from the power circuitry. The power circuitry comprising of a star topology power and ground layers is built on one board while a separate board houses the pre-amplification circuit. An isolation layer separates these two boards, which further minimizes interference."
"The AMG-STA uses the ?Single-Ended, Non-Negative Feedback? Class-A module partners with a new ?Double feedback? Class D circuitry. The Class D oscillating frequency has increased to 700kHz, which is 1.4 times that of the STA-9."
