Elite M-90 Reference Stereo Power Amplifier

Pioneer introduced the M-90 Reference Power Amplifier in 1987, to be used in conjunction with the C-90 Reference Control Amplifier. In the January 1987 issue of Stereo Review that ran the "Not Evolutionary-Revolutionary" advertisement, here is what Pioneer said about the M-90:

"The M-90 is a superb high-power stereo amplifier, utilizing dual-mono construction. It is conservatively rated at 200 W/CH into 8 ohms and delivers 800 W/CH of dynamic power at 2 ohms. The wide dynamic range of the digital sources can now be reproduced effortlessly, with any loudspeakers. The M-90's high current capacity of 47 amps can handle the challenge of the most complex speaker loads. To further enhance S/N ratio and channel separation, relay-operated electronic switches and a long shaft volume control keep the length of signal paths down to a minimum. Why include a high quality volume control on a power amp? To pursue the straight wire-with-gain philosophy when using a CD player connected directly. Pure sound, redefined."

The M-90 was virtually distortion-free, having only 0.003% THD from 20-20K Hz @ 8 ohms, and had a S/N ratio of 125 dB! (See the complete specifications at bottom of page.) The M.S.R.P. for the M-90 was $950.00. It was superseded by the M-91 in 1989.

MACROM INTEGRA 54.10 (car audio) ( SOLD)
















Mid MACROM Integra 54.10 split coaxial..
sebenarnya speaker ini jenis coaxial karena tweeter nya berada tepat ditengah2 mid nya
tetapi kemudian saya ubah menjadi 2 way terpisah dg melepas tweter sehingga antara mid dan tweeter terpisah..
Karena tweeter dilepas otomatis di tengah mid ada lubang yg besar , kemudian saya tutup dg dust cup yg kebetulan dg ukuran yg sama
Di rangka mid nya tdk ada lubang buat skrup ...saya kurang paham bagaimana cara pasang nya..
















tampak tulisan type nya : Integra 54.10 2 way system triple magnet
















mid ini punya ukuran hanya 4 inch















magnet nya model berlubang tetapi ada tutup nya

















tweeter model dome masih original...

The Elite C-90 Reference Control Amplifier was introduced by Pioneer in 1987 and manufactured through 1988. Like the M-90 Reference Power Amplifier, the C-90 was a twin-mono design with separate power supplies and circuitry for both left and right channels. It was designed to handle state of the art video as well as audio inputs.
Front panel layout included Video input switching for TV Tuner, VCR1, VCR2, VCR3 and VDP on the left, and Audio input switching for Tape 1, Tape 2, Tuner, Phono and CD on the right. The Main Power switch was located in the upper lefthand corner with Standby switch next to it. The motorized Volume knob was on the upper right of the panel. Beneath these groups of controls was a narrow silver band having the infrared sensor for the remote control and small leds with nomenclature indicating the control amp's current functions.
The back panel featured RCA jacks that was spaced wide enough apart to permit the use of audiophile grade interconnect cables. There were two unswitched AC jacks and one switched AC jack for powering other components.
A particularly nice touch was the visible copper plating for all nomenclature which duplicated the copper plated chassis appearance inside the unit.
The C-90 was favorably reviewed by Stereo Review in the April 1987 issue (see below). The C-90 had a list price of $800.00. It was superceded by the C-91 in 1989.
