Tell me about the little guys up above.

I’ll just leave this here.

Buckeye implementation of the Purifi Eigentakt 1ET7040SA amplifier module.

the 1ET7040SA shines for those with sub 4ohm speaker loads (40A peak current capability vs. 25A peak of the 1ET400A). For the most discerning 2ch music lovers, a pair of 1ET7040SA monoblock amps will drive even the most difficult speakers.

Specifications: (1) Purifi 1ET7040SA module (1) Mircro Audio SMPS1k-PFCR2 (w/Active Power Factor Correction) 950w @ 2ohm (peak) 500w @ 4ohm (peak) 250w @ 8ohm (peak)

Audiophiles love music and sound, not gatekeeping.

Two considerations: License transferability and inputs.

License: the license if for the device has limited transferability. If you buy a Denon x3800h based dirac license, then when it dies and you buy a Marantz, the license doesn’t transfer. (If your device dies and you buy a direct replacement, they will transfer).

If you buy a PC license, and the PC dies they will transfer to a new PC, but not if you buy a Mac.

The exact limits are not super clear and why the license isn’t transferable is beyond stupid. But there it is.

Inputs: Get the PC license and anything routed through it gets Dirac goodness. If ypu are PC only you are good. But like me, a turntable doesn’t go through the PC and goes straight into my AVR bypassing Dirac goodness. Same for dedicated cd and blueray players. If they route through the HTPC you are fine. If not you are sol.

Also note the pc license doesn’t do Linux. Windows and Mac only. I would give my left testicle for a linux compatible version because its stable enpugh for an aplliance like experience unlike windows which is always doing some bloaty stupid thing.

Blue ray, cd, vinyl

DSP - change the frequency response endlessly for free. Once you have minimally competent speakers DSP can make any speaker sound like every speaker if your willing to fiddle enough.

While a certain level of tinkering give amazing results fast, beyond that, you get ‘different’ not ‘better’.

I have a pair of C-9 and RC-70s and love them as a budget audiophile play. It’s a lot of speaker for the money and availability in Canada was good.

With Dirac, they become exceptional!

Missing out on nothing. CD format is perfect sound forever, everthing else is features other than sound quality or marketing.
