The difference I am pretty certain is the type of capacitors used in the bypass. The poly is the standard, and the Anniversary used to be Jupiter Type 2 but now I believe that Steve is using Miflex copper capacitors for the upgraded bypass.

There is a significant sonic difference I believe. (Though I have had the poly caps and the Miflex caps both in separate components, I have had the Mifle in a bypass in the ZROCK2 and the poly in a non-bypass ZROCK2. I would describe the Anniversary with Miflex as more revealing of detail and dynamics--noticeably, more than a subtle difference.

But there's this: you'll hear more of everything with the Anniversary, which means you'll hear shortcomings of source and cabling etc. In my case that led me over time to upgrade, upgrade, upgrade. . . and at times to be more about the gear than the music. I've come across to the other side of that now with all my components with great sources and upgraded caps but one (ZTPRE) and very happy . . . but it was a journey of time and money. But that may be just me. I've been susceptible to that on my audio journey, not everyone is.

So for me it's a worhtwhile upgrade, but I can also understand choosing the poly upgrade and being very happy without embarking on a longer audio trek.

Hope this makes sense and helps.

A good rule of thumb with Decware is to ALWAYS go for the full upgrades on the front end.  It will save you from having to send it in later.  Steve tries to keep things affordable so he offers more basic versions but he constantly innovates and makes thing better with time via upgrades.

I see that Lon has responded as I was writing this.  I was going to point out as well that the $250 is an Anniversary mod as the unit is already "type 2."  I still think it's advisable to go for the mod since you can always, and probably will, upgrade sources, etc. as time goes by and you'll want the amp to be the best it can be.

Thank you for the quick responses. I will call and add the mod on Monday
As far as  my other equipment, I  have
vpi prime tt, ps audio stellar phono pre, don sachs linestage, bel canto e one streamer , and spatial audio x5 open baffle speakers.  I think my gear is up to snuff at this point and do not expect the anniversary mod to cause any upgraditis ( at least for the near future )

Steve noted in the description of the type 2 that the Anniversary mod was now standard.

It's in the shopping cart as a $250 option so it doesn't seem to be standard unless he didn't update the cart info.

Not sure if this link/thread helps.  Unless I misunderstood, it comes with the anniversary mods....

On a few posts down from the thread link you posted Steve says the following

The Beeswax Bypass Cap mod on the original TORII JR., was $400. †On the new TORII JR., the amp already comes with a poly bypass cap mod standard, but there will be an upgraded version of it that replaces four of the caps with the same Mundorfs used in the signal path. †This option will cost $250
