Have you heard of Gallium Nitride? Have you heard what it is doing for class D amps? If so, cool, welcome fellow interested personage. I'll do my best to keep you entertained for a while. If not, let me provide you with a 2-and-a-half line summary. Gallium Nitride is a semi-conductor, much like silicon, that has slightly more favorable electronic characteristics. Electricity can move through it faster, enabling transistors made from it to switch faster. GaN (as it is becoming increasingly abbreviated to) class D designs can supposedly switch twice as fast as old school MOSFETs. Several companies are dipping their toes into the GaN pool. Panasonic, Peachtree, Java Audio and Orchard Audio all have GaN based power amp offerings on the market (or at least Peachtree should by now) but not a lot of people have heard them. They aren't that popular... yet. I have an Orchard Audio Starkrimson amp (and DAC for that matter) that I am running in at the moment and it is very good indeed. It is clear, clean and powerful while also being resolving, delicate and non-fatiguing. I suspect I can get it to sound even better again as I haven't yet gotten around to trialing it with different speaker and interconnect cables. I also have some Purify 1ET 400A modules on hand which I plan to assemble into a power amp just as soon as I can get my hands on a case and power supply. I'll share my thoughts on the amps, their sound and performance as time goes on but for now I'd like to hear from others. Have you heard a GaN design? If so, do you have any comments you would like to share?

Who knows how to activate the power amp input? I ask this question is because i have 2 Roksan M2 integrate amplifiers, wondering to use as bi-amp. As long as the power amp input can be activated. Some messages have been sent to the dealer and distributor for help, but nothing comes back. See if anyone have any suggestion for that. Thanks, Beier

Classic British sound power amp and preamp. Never had an issue with them since purchasing them 4 years ago. Plenty of reviews online. I have tried Quad 33 firstly but Quad 34 was a better match to my hearing. Some very small scratches on top cover but overall great condition and functionality. Will be very well packed if require shipping. Only selling together.

For A32, The is a scratch on the left, back of the top cover and a small ding on the top, left of the front panel, photos attached (last 2 photos). Not really visible unless you are taking a close look. I am not looking at separating the package at the moment. Local sales preferred as the the A32 weights 40kg alone! Will ships interstate if the the buyer is willing to organise and pay for the shipping. Photos:

Selling a combo of Pre & Power, Technics C2000 & A5000 in great condition, very nice looking and beautiful sounding. Bought these from a fellow member few years back, serving me well during the time, and now is the time to change. Note: This is 100v Japanese version so a step down transformer required. I'm willing to throw a 1000va step down transformer and a Logitech universal remote control with the sale. No original packaging so local pickup preferred but I am happy to box and ship interstate at buyer's cost and risk. Any questions, please ask. Thanks for looking! TECHNICS SU-C2000 The Technics SU-C2000, released in Japan in 1993, is a handsome high-fidelity stereo control amplifier. The SU-C2000 has a frequency response of 1 Hz to 120 kHz and an impressively low level of total harmonic distortion (<0.003% THD). Its input sensitivities are 0.15mV (MC), 2.5mV (MM), and 200mV (line). One salient feature is the unit’s virtual battery operation circuitry, which prevents interference and noise from the power source. The chassis uses THCB (Technics Hybrid Construction Base), with a hard rubber base and a copper plating chassis bottom, whereby vibrational interference is minimized. The SU-C2000 is a wonderful, quality unit with fantastic specs, a great design, and outstanding sound. SPECIFICATIONS Frequency response: 1Hz to 120kHz Total harmonic distortion: 0.003% Input sensitivity: 0.15mV (MC), 2.5mV (MM), 200mV (line) Signal to noise ratio: 68dB (MC), 88dB (MM), 104dB (line) Channel separation: 55dB (line) Output: 200mV (line), 1V (Pre out), 7V (Pre out Max) Dimensions: 448 x 129 x 344mm Weight: 9.5kg https://audio-database.com/TechnicsPanasonic/amp/su-c2000-e.html TECHNICS SE-A5000 The classAA scheme is adopted as circuitry, voltage control amplifier and electric-current drive amplifier are carried in a right-and-left channel, and it has VC-4 amplifier composition which consisted of a total of four sets of amplifier. The voltage control which determines an audio property serves as a differential-amplification input stage by a one chip Dual FET, and first class amplifier of the Darlington stream composition with the output transistor of Pc150Wx2ch, and has realized the low distortion for which the threshold of a measuring instrument is pressed. Moreover, electric-current drive amplifier which drives a speaker,It consists of a high-slew-rate swing amplification stage which allotted the feed-forward type bootstrap power supply by the FET difference input, and an output stage of Pc450Wx2ch and four-step Darlington which uses the output transistor of 3 parallel. An electric current for this to obtain powerful power is supplied at the high speed 50A/mus. A total of three transformers of two power transformers for electric-current drive amplifier of each right-and-left channel and one transformer for voltage control amplifier of a right-and-left channel are carried in the power-source part. And it has perfect symmetry composition which carried out thorough exclusion of the cross interferencee of a right-and-left channel. Moreover, the mass electrolytic capacitor with a total capacity of 89,400 micro F is carried. Specifications Power output: 170 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.007% Damping factor: 120 Input sensitivity: 1.2V Signal to noise ratio: 120dB Speaker load impedance: 4Ω (minimum) Dimensions: 480 x 207 x 475mm Weight: 34kg Year: 1990 https://audio-database.com/TechnicsPanasonic/amp/se-a5000-e.html

Australian retail price for these is over $20,000; Mark Levinson No. 531H Monaural Power Amplifier The No 531H and No532H are both true mono-block designs with independent power supplies for each channel and are rated at 300W per channel into 8 ohms. The transformers and power supply designs deliver unsurpassed dynamics and transient responses for today’s demanding audio formats and provide stability with even the most difficult to drive loudspeakers. Fully differential circuitry ensures that balanced input signals stay that way throughout the signal path and traditional Mark Levinson “Hurricane” binding posts offer secure termination to the loudspeaker. The four amplifiers in the No500H Series are the definition of truly outstanding performance in their respective categories. Drawing from the Mark Levinson heritage, while utilizing a new, straightforward, balanced, current-feedback design creates a new series of amplifiers that must be listened to in order to be fully appreciated. The final result is impressive even for the Mark Levinson high standard of excellence. Main Features •Reliable, high-power in four different channel configurations provide ideal solutions for any system •Isolated chassis and signal grounds minimize noise, optimizing detail, even at low listening levels •Fully-differential circuitry with both balanced XLR and single-ended RCA inputs •Ethernet and 12V trigger control capability for system integration Inputs one balanced XLR input per channel; one unbalanced RCA input per channel Speaker Connections one pair “Hurricane” loudspeaker outputs with banana-plug sockets per channel (banana-plug socket not available on the 230 VAC models) Communication and Control one Ethernet 10Base-T port; one 3.5mm mono (tip/sleeve) mini plug trigger input, 3-12Vdc; one 3.5mm mono (tip/sleeve) mini plug trigger output, 3-12Vdc; 3-pin IEC standard power connector Rated Output Power into 8 ohms 300W/ch (20Hz to 20kHz at 85dB, reference level: 2.83 Vrms Input Sensitivity 2.83Vrms output at 130mVrms input Gain 26.8dB Input Impedance 60 kΩ (balanced); 30 kΩ (unbalanced) Power Requirements 100V~, 120V~, 230V~, factory set for destination country; Power Consumption 300W Height (with feet): 7.65" (19.4cm); (without feet): 6.97" (17.7cm) Width 17.75" (45.1cm) Depth 19.83" (50.4cm) Weight Net Weight: 52.5lb (23.8kg); Shipping weight: 62.5lb (28.4kg) Tags: Krell, Mcintosh, audio research, luxman, accuphase, esoteric Photos:
