Très bon appareil, esthétique et rendu sonore très qualitatif ! Actuellement couplé à une paire de Coral BX-1500 et une paire de Celestion Ditton 66 legend, le rendu est très satisfaisant. Par ailleurs l’esthétique vient s’ajouter à la très bonne qualité du produit. Très imposant de part ces dimensions, cet ampli-tuner qui fait aussi office de pré-ampli est remarquable. Je recommande fortement ce produit de chez Pioneer !

Extremely well-built and one of the most beautiful stereo receivers ever made. Knobs and switches are a joy to touch and operate, power meters are tastefully integrated within the face plate. Sound is clean but rather neutral, with a disappointing lack of bass from such an enormous piece. Complex internal layout and may suffer from cold solder joints, rendering it inoperable. Stunning walnut case. Built in a magical era never to be repeated.

I love my sx980

I picked one up a few weeks ago, unaltered and in as new condition, not a scratch or ding in the wood. Tuner section is awesome, and everything works perfectly.. They really don't make electronics like these anymore, the last of an era for that warm sound unless you have lots of money. These have big transformers and main caps, and are definitely worth the money they are fetching now if you find a nice one that isn't all butchered up. 80 wpc with a good set of speakers, can rock the house with loads of real headroom. The silver era will be missed

The 90s were dawning and I decided it was time to move one from low-power amps to something with a healthy dosage of watts. New stuff ? Budget receivers had hideous sound featuring cheap ICs on their power stages and good quality was as affordable as a trip to the moon. I decided to go vintage for the sake of my economy but got hooked on it for life.

U$ 250 dollars lighter and a couple of incipient hernias from moving around the 19 kgs this beast weighs I was blasting the sweetest sound I had ever heard. Elna capacitors, Nec transistors, state-of-the-art circuit boards, it had it all.

Granted, it did broke down on me a couple of times, but nothing that couldn't be repaired with original components within my budget. I never needed to recap it because it was not necessary and I don't believe in altering the original sound.

I really expect to enjoy this unit for another 20 years because if I have to buy a current receiver this good-sounding(been tempted by the Denon DRA-397), it will not only set me back a couple of grand but I know the POS will die on me within 5 years like everything engineered with planned obsolescence these days.

Only drawback I can point out is this is not a high-current amp. The damping factor is as skimp as 30 and it only pumps 15 watts more in 4 ohms than it does in 8. But paired to my Klipsch F2s and JBL 12 SUB you can rarely realize this fact.

If you ever come across a mint unit, buy it without hesitation, it's totally worth you while 8a lifetime in my case, I hope).



re: SX-980

I,m a electronic engineer. I work on vintage audio as a hobby. When your receiver gets freshly capped it's like night and day in performance. Your frequency response goes through the roof. If its a piece you plan keeping recap it,you wont regret it.

re: SX-980

I'm an architect and don't understand electronics. What does 'recap' mean? Thanks

re: SX-980

New to this hobby -- what is recapping? Thx

re: SX-980

It is not a sin to recap vintage electronics. I am on this page for the very reason that my customer wants his SX-980 recapped. Capacitor technology has come a long way in 40 years. And without question, capacitors age with time. For this era electronics I use Nichicon Super-Through capacitors for the power supply, Elna Selmic II (RFS) silk-fiber capacitors for the bypass caps. The sound does nothing but improve. That said, choosing the wrong capacitor can make your prized amplifier sound harsh, thin, weak or muffled. You have to know what your customer wants the end result to sound like and how to get there, this not a task for the inexperienced.

re: SX-980

I have a sx 980 which plays very good. Unsure how much better it could or would sound with a recap. When do u know it's time to recap and is recap the only key items to change out.

re: SX-980

Capacitors age slowly. Think if it like automobile shock absorbers, which is the what capacitors are, electrical shock absorbers. Given enough time, they will degrade, but so slowly, you never notice. When you have the time and the money, find a trust-worthy and fair-minded technician to go through it for you. Expect a bill in the neighborhood of around $250-$300. If you like the sound of it now, you will be thrilled to hear the improvement.
