Magical Marantz 22## receivers


Why is it generally accepted that caps in a vintage speaker crossover should be replaced but some how these mid-fi (at best) 70’s vintage receivers seem to get better (and more expensive) with no maintenance. I would love to see someone bench test one of these beauties with the “tube like” sound.

I have a vintage Marantz 2230 because I owned one when I was 17 years old. Reminds me of my youth. 

Hi Kosst

That's more than likely why. The 3400 doesn't have any bigger caps. I went down to the shop just a few moments ago and looked at a circuit board close up and didn't find any residue. I'm going to have the guys check as well, we're pretty picky about cleaning up boards and parts.

Thanks for the heads up! One thing I love about the biz is, there's always folks out there discovering something useful to add to the mix.

Hi Kosst

The Pioneer SX-3400? Where specifically on this unit? I've been tuning these specific units for many years now without anything failing on any of them. Are you sure they are talking about the 3400?

I'm happy to reinvestigate, I have 4 of these units sitting right here, including one taken completely apart so it will be easy for me to see exactly where you are referring to.

thanks

"...And yes they get much better with age."

Seriously? Difficult to substantiate since most don't remember how they sounded when new. I've owned an SX-980 since new and still can't remember...(I do have a good excuse..)

Hi Kosst

Sorry that I gave the wrong impression. Now that I look back on the OP, I realize he was talking about the Marantz 22..s. The units that I get in are the entry level Pioneer, Technics and such. Very light weight and low mass. For example I work alot with the Pioneer sx-3400. It's a very simple unit to tune and sounds amazing. Of course I'm using my speakers which are extremely easy to drive.

Yep, I don't use the big stuff, as you pointed out, way to complicated.

I apologize for not being more clear.

I owned a Marantz 2230 and it was nice.  I liked the flywheel tuner the best.  But when I replaced it with a NAD 3140 my large Advents really came to life.  It was no contest.

I love the sound of the old goodies, just received another 3 of them this week. You have to know which ones are the special sounding ones. And yes they get much better with age. I don’t like the sound of anything complicated and I mechanically tune all of my components after I get them. I think I have had one with a bad cap but that was it.

When I look to make a purchase, if it says recapped I keep my distance. The sound of older solid state parts (with a good design) sound very much like tubes, in some cases even better. I bring in several different models during a years time to find the ones that really perform.

Last year and this year I’m putting these head to head up against HEA’s best and well lets just say a lot of my newer HEA has been up on Audiomart, and I hope to get more of it sold this year. I bet I took about a $60,000.00 bath last year on the amps and DACs I bought. Some horrible sounding stuff, and on Stereophile’s recommended list too.
