Hello. I am a first time poster hoping to get advice from the community. I have had these Pioneer units since 1977 (80W/PC). They are quite used as I listen to music all the time, 4-5 hours a day. I had them serviced about six years ago and now they have developed new problems. I took them in again and the serviceman cannot simulate the problems and recommends an overall service. I do not want to spend more money without assurance that the problems will resolve. So, I am making this post to ask whether there is new equipment out there that can sound as well as these. I am looking for brand/model recommendations. So far as listening, I only stream music with my iPad through these and mostly listen to classic rock of 1970's through 1990's. These are connected to four HPM100 Pioneer speakers (100W/per) Thank you for your help.

Intermittent faults are the worst- I woked on Elevators s a service engineer and it was the same- 'it breaks down as soon as you leave our building!' - Like it was my fault. I learned to say ' Whos lift is it?' Occasionaly went down like a lead-balloon , but you get my drift.
What is the AMP and Equaliser doing/not doing?
 
Have you run the amp without the equaliser gizmo attached? No bass is usually a cap on the front end.TO BE HONEST, I think you need to bite the bullet as its a strip and scope job to find where the signal is losing out.
 
Thanks, but I'm really not interested in repairing these. I am asking for help with choosing a brand new equipment alternative.

Can I connect my ipad to a (new) EQ and then a (new) power amp (not integrated amp) to drive my four speakers?
 
Ipad and similar output <120mv, so you will want an 'Aux ' input with that is spec. Most amps will have this facility. I haven't seen anything with so many tone controls as what you have shown that Pioneer has. I did have a 'Realistic' Graphics Equaliser back in the late 70's - but not had the need since. Most stuff around works of a compression that lacks the need for such tonal control as the EQ . If you are using an iPad, a graphic equaliser is an app you can download, Im sure- As a suggestion, one of those bluetooth receivers will do what you want as an input interface- I use one in my old Range Rover that doesn't have bluetooth- I plug it into the 'aux' socket behind the center consul.
