My subjective opinion with the Mod86 V3 is that it simply sounds better than the Mod686 which I also own. Vocals sound more natural, there is more detail present. Not that the 686 is bad, but the 86 V3 is an improvement. Its comparable to the Folsom 7293 in my opinion when you gain match them. They are two of the best SS amps I have ever heard.

Fantastic. Thanks for spreading the word. The chassis you used can be used with the Modulus-286 (and -186) as well.

There are plenty of completed Modulus-86 in this thread. I thought yours was the first Rev. 3.0, but it turns out mkrawcz beat you to it: Post #5691.

I checked and the weight of my speaker cable had rotated the spades enough that they were touching.
This is why I hate binding posts. It's a horrible connector. The banana plugs aren't much better. I suppose eventually residential hifi will grow up and use speakON connectors as the professional world has done for decades.

The only reason I provide binding posts is that those are expected on consumer gear. I have sold a couple of amps with speakON only, and the first question was always: "Can I get it with binding posts instead?" Market wants. I deliver. Even if I don't agree with it.

They are indeed.

Gorgeous chassis and very tidy build. Tom, as I’ve not been following your threads as scrupulously as before, did you post a link either here or on your commercial site detailing these? I must say it’s rather a slicker look than the Modushop chassis offered on your earlier limited kits, or on the DIY ACA.

Echo Chrisb's sentiments Tom - neat build and good looking chassis for the new Modulus-86 amp.

What are the dimensions of the Takachi chassis?

I don't have the chassis listed on my website yet. I plan to do that in the not-too-distant future. They are indeed very nice, but also a bit pricey. They're $469/each. I have both black and "silver" (i.e., clear anodized aluminum) available.

The chassis measures roughly 300x300x90 mm. Give/take, free from memory, usual disclaimers apply.

I'm planning a couple of demo builds as well, so I'll have something for those who prefer to buy fully assembled.

Tom

Hello Tom,


do you consider selling the rear panels individually? That would improve any diy enclosure a lot.


Thanks
Stefan

No. I can't buy them individually, so I can't sell them individually. It also wouldn't really make sense to sell the panels individually as they really only work with the rest of the chassis.
