AMR PH-77 Reference Class Phono Equaliser

[Κώστας Φ.]

"After years of extensive in-house development and close collaboration with recording engineers and archivists from the BBC; the British Library Sound Archive; The Institut fürRundfunktechnik GmbH1 and Sveriges Radio AB2, AMR is pleased to announce it has commenced shipping of the PH-77 Reference Class Phono Equaliser.

"The PH-77 is the only phonograph source able to lay claim to exclusively feature a comprehensive catalogue of 22 equalisation (EQ) curves. Every LP record ever made may now be replayed using the one and only correct equalisation curve.

"Together with 8 levels of gain; 64 steps of load; 3 inputs for unprecedented flexibility in cartridge choice/matching and an onboard 24bit/96kHz DAC, the PH-77 also is a pure single-ended, Class A, zero negative feedback design. All low-level signal connections including the cartridge are coupled directly. Overall, only two coupling capacitors are employed: one is a custom-made silver foil capacitor that follows the equalisation block; and the output capacitor is the same German-made film and foil capacitor used in the CD-77 CD-Processor.

"The PH-77 uses sonically superior valve-based rectification with 2 x NOS EZ80 and double C-Core 20H choke filtering implemented fully dual mono. Instead of traditional regulators, the PH-77 employs a far more elaborate set of 4 virtual battery supplies, characterised by zero negative feedback and lowest possible noise. These are followed by a further 28 stages of passive power supply filtering, 8 of them utilising costly large value film capacitors.


"All of the following functions are completely adjustable in real-time either on the front panel or from the included aluminium remote control.

• 8 levels of gain 72, 66, 60, 54, 48, 42, 36, 30dB for complete cartridge compatibility.
• 64 steps of load for pinpoint resistive and capacitive loading.
• 3 switchable inputs to select the desired cartridges and tonearm combination: be it elliptical or spherical stylus cartridges; stereo or mono cartridges; fixed or flexible (linear tracking or pivoted) tonearms; with Moving Magnet or Moving Coil cartridges.
• 32 steps for Moving Coil, 32 steps for Moving Magnet.

"The worldwide recommended retail price of the PH-77 is EUR7,800 (excluding VAT)."

Δεν κατάλαβα κάτι.

Ψηφιοποιεί το αναλογικό σήμα της φωνογραφικής κεφαλής, η απλά έχει εκτός από phono stage και DAC on board? (για να μπορεί να δεχθεί και ψηφιακό σήμα απο ένα transport)

Πάντως, για όλα αυτά που κάνει δεν είναι και τόσο ακριβό σε σχέση με τον ανταγωνισμό (το θέμα είναι ποιός έχει πικάπ με... 3 βραχίονες και κεφαλές... :143
