(solid state) dg tampilan yg sangat mewah..
Body besar yg dibalut kayu mengkilap disisi kanan dan kiri
Panel depan jg tampak mengkilap warna hitam dg kombinasi garis2 warna gold
Power ini di produksi sekitar th 1987 yg merupakan produk pioneer yg berkelas...
berdasar dari data yg saya dapat dari web pioneer , power ini mengeluarkan daya 2 x 200 W(8 ohm)
Pada panel depan bagian bawah kiri ada sebuah selector input (control amp/cd direct/line) dan di sebelah kanan ada volume control .
Antara selector dan volume control terdapat tutup yg bisa dibuka , ada 3 knob kecil2 (push) : pilihan spk a/b dan on/off lamp led nya
Led nya berwarna orange , bisa ditampilkan atau dimatikan
Tampak atas body power amplifiernya ...kisi2 kecil yg banyak untuk mengeluarkan hawa panas dari power amplifier ini...
Tutup bagian bawahnya jg dg kisi2 kecil spt yg atas tp dg bahan tembaga merah..
MEWAH dan EKSKLUSIF....

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 It was superseded by the M-91 in 1989.
