Description
Manley Laboratories The Wave Valve Preamplifier with DAC Later Improved 24/96 2nd Generation Version An extremely rare opportunity to buy a proper bit of high-end kit here!Designed and built with a cost no object attitude by a manufacturer with impeccable history. That rather unusually spans both pro audio and domestic hi-fi.It cost around £8000 15 years a go and an equivalent unit would no doubt have to be priced at well over double that amount these days. Regardless of cost, it sounds sublime and has been a pleasure to use always.I count myself lucky to have owned this and will be genuinely sorry to see it go. As these hardly ever come up over here in Europe, this one had to be sourced in the USA around 5 years ago.It was then sent to Manley Laboratories for a full check up and to have the PSU unit converted to 240v.Upon arrival in the UK the faceplate of the main unit was found to have a chip in one corner. So Manley sent a new replacement faceplate and paid for it to be professionally fitted over here.It has worked perfectly ever since and continues to do so. Cosmetically, overall it is in very good condition despite picking up a few minor marks here and there. However, most of these are to the casework of the PSU unit rather than the main unit and do not detract greatly from its overall appearance in my opinion.Please see the photos above.The separate PSU unit is connected to the main unit by a substantial 2 metre long cable. So can be positioned well out of the way. Will be supplied with:Remote ControlInstruction ManualThick Schuko Power CableSpare Faceplate (chipped corner) Please get in touch if you have any questions.Prospective buyers are most welcome to inspect and hear this rather special amplifier.Collection in person is much preferred. Alternatively, I may be able to deliver in person. If not too far and my fuel costs are covered. I would really rather not risk trusting this rarity of an amp with a courier. Again, please get in touch to discuss.

It starts with 4 digital inputs spanning the AES/EBU, SPDIF, Toslink and ST formats. February 2002 brought us a new 24 bit 96KHz digital to analog converter board designed by Fred Forssell. We merged this new DAC with an improved tube stage and added two analog balanced AND two unbalanced inputs. Outboard power supply too. Three sets of outputs and a processor loop are also all switchable from the front panel AND (big news...) REMOTE CONTROL!!!!!!!!!!!!! MANLEYs first piece with remote control is a total over-killer The *entire* faceplate can also be operated by the remote, especially and finally including the volume control. The WAVE is a unique product combining a killer 24/96 Digital to Analog Converter with a full-featured audiophile analog vacuum tube preamplifier. It is one of the very few products equally at home as the heart of a professional Mastering studio facility as it is as the centerpiece of an audiophile home system. The combination of features and functions came about from analyzing existing systems and finding them functional but lacking in elegance in signal flow, operational convenience, and synergy. We set out to build something we wanted in our own living rooms, something that could be upgraded as new standards evolved, and something that could be flexible to work with mixed balanced, unbalanced, analog, and digital connections. A swiss army knife of sorts... The digital board used in the first generation units, (the First Waves as it were) was designed around the ULTRAANALOG 20-bit DACs, the AES-21 jitter reduction input module, and the Pacific Microsonics HDCD decoder. This chipset ruled the 1990s audiophile digital world. In early 2002 we commissioned an excellent 24 bit, 96KHz DAC board design from talented designer Fred Forssell for the second generation units, in current production as of this writing. The WAVE accepts four digital inputs in the following formats: AES, SPDIF, TOSLINK, and ST Glass Fiber. The four analog inputs come as stock 2 RCA + 2 XLR. Other configurations can be custom-ordered as desired. To provide extra flexibility in system integration, we have included an Insert Loop (term borrowed from the recording studio world) perhaps more commonly referred to as a Tape Loop or Processor Loop in Audiophile-land. Three outputs are provided: outputs 2 and 3 can be switched; output 1 is always on.

Measurements done with new set of batteries. Distance of 9-10 ft, the maximum angle is 65-75 degrees.Distance of 12 ft, the maximum angle is 60 degrees.Distance of 13 ft, the maximum angle is 45-55 degrees.Distance of 16 ft, the maximum angle is 45 degrees.Distance of 20 ft, the maximum angle is 25-35 degrees.Distance of 25-27 ft, the maximum angle is 0-15 degrees. This is the maximum distance-angle the remote will do.DIGITAL SECTIONBurr-Brown PCM1704 D-A converters operating at 96 KHz at all timesAll inputs below 96 KHz are upsampled to 96 KHz before conversionThe upsampled output is clocked out via a Low Phase Noise/Low Jitter precision crystal oscillator to eliminate any interface jitter or timing problems with the incoming datastreamMultiple power supplies are used, with additional regulation and filtering located at all critical componentsDifferential Passive LC filtering is used on the voltage output of the DAC PCBHigh Speed JFET Current to Voltage Conversion with differential output is used to drive the Passive LC FilterIt will wash your car, clean your windows, make coffee and sound good all at the same time...ANALOG SECTIONALL-TUBE BALANCED LINE AMPLIFIER using 2 x 12AX7 plus 2 x 7044 or 5687 dual triodesBALANCED I/O and UNBALANCED I/OINPUT SENSITIVITY: 494mV (-3.9dBu) yields 1V outMAXIMUM INPUT LEVEL: 9.75Vrms produces 19.86V on output at 1KHz before clipping +22dBu produces +28.18dBu on output at 1KHz before clippingMAXIMUM GAIN: 12 dBMAXIMUM OUTPUT: +30 dBu, 25 V rms (70V P-P) (+31dbu @ 1.5% THD)+8.25 dBu digital full scale (2.0 V Rms)FREQUENCY RESPONSE: 20 Hz to 20 kHz ±.5 dB 8 Hz to 45 kHz ±3 dB THD+N: 0.015% 20Hz - 20KHz bandwidthNOISE FLOOR -88 db (20 Hz - 20 kHz) (-90 A-Weight)S/N 120 dB analog (96 db digital)L/R Volume Control Matching .2 dB (from -50 to max)ADDITIONAL FEATURESMOTORIZED ATTENUATOR WITH FULL REMOTE CONTROLEXTERNAL POWER SUPPLYDIGITAL PHASE / POLARITY SWITCH,INSERT FOR TAPE MONITOR, PROCESSOR LOOP, ETC.MANUAL MUTE, WARM-UP MUTE & STANDBY MODES.Manley Blue anodized 3/8 thick by 19 FRONT PANEL, 18 BLUE LEDSUPGRADEABLE DIGITAL BOARDMANY CUSTOM OPTIONS AVAILABLE INCLUDING: ANY COMBINATIONS OF BALANCED AND UNBALANCED I/O, OR ANY COMBINATION OF DIGITAL INPUT TYPES.
