That there makes some sense. I am annoyed at myself for not realizing that intent from your block diagram. I know little about the internals of the Dectet, but is there confirmation this specific device can actually (as opposed to theoretically) prevent noise back flow? The reason I ask is not to doubt your proclamation, but rather to factor into my decision to purchase one for the same reason as I have a few of these types of energizing wall wart supplies.
I donāt follow this forum. Someone alerted me to this discussion, so I thought Iād clarify. Feel free to return to the discussion!
Itās in the last section of the review.
Power Cables: PS Audio AC-12 (wall to P5), Cardas Clear Beyond (Cavalli Amp),
Cardas Clear (Mutec Ref-10), Cardas Clear to all DACs under test
Cardas Clear (SR-4, SR-7), Pangea AC-14SE MkII to all other PSUs,
Pangea AC-14XL to Dectet
To be honest, I donāt know. I have not compared replacing a Dectet with just an extension block to see if this back flow is audible.
What I did try initially, thinking it was better hygiene, was to connect the Dectet powering the SMPSes to a separate AC circuit, not the dedicated circuit to which my P5 is connected. I figured this would completely eliminate any back flow contamination. However, I actually got better SQ connecting the Dectet to the P5, so sometimes you just to experimentā¦

Roger that! I like the philosophy of its implementation. Maybe @Paul can chime in. Since itās now a discontinued product, not sure if the 30-day return policy from a reseller applies. May end up being an expensive experiment for me. Regardless, I like where you went with this hole idea. I do believe it has merit. Thanks man!

Couldnāt you do the same thing with one of these and you can send it back to AA if it doesnāt work out. Plus less than half the price of the Dectect.
No idea. i already had a Dectet lying around.
Possibly. I would just want confirmation that it will prevent back flow noise based on internal design before pulling the trigger on anything. This would be an addition to my system based on paper specs alone. In other words, the SMPSs are performing a function where regenerated power is non-influential so Iām solely concerned with the noise those SMPSs produce doing an about face and marching back into my P10s. It seems to be an exercise of cheap insurance.
Thanks for the link on the AQ filter. The price tag is very nice!
@austinpop - Rajiv - Thanks for the feedback. Iād give Shunyata Research Alpha NR power cords a shot, rent them from thecableco.com library and run an A/B comparison. You might want to do some white paper reading on their CCI filtering for component to component RFI filtering (back flow noise). I use Sigma NR (20A, 6ga) into the P20 from SR BLUE duplex bottom for the 2,000 VA capability; however, looks like the SR Alpha (8ga, 15A) will work on the P5. I use SR Alpha NR for all PSA & REL (DMP, DSD, BHK PRE, BHK300s, dual REL S3 subs) off the P20. Then Alpha NR from top of single run 20A 10ga SR BLUE duplex to EVO3 Sirius strip (30+ dB plug to plug isolation & 50+dB RFI suppression), then SR Delta NR (10ga, 15A) to (4) Farad Super3 LPS for AQVOX-SE, Giga FOIL, Matrix, and Nucleus+, separating Ethernet & streaming from all my PSA and REL components.
