    DC Blocker

    I don’t think a DC blocker would block a transient spike anyway, because they are designed to block DC offset. When they say “DC spike” I am not sure but picture a brief transient like a lopsided AC waveform that only lasts a half cycle or less. Strange that PS Audio would change course, as...

    FS ESL 11A gloss black 3 months old 7000$

    50% on the logarithmic dB meter is what, 4.5W?

    DC Blocker

    Absolutely. If the software has the ability to parse through valid IR codes it should be able to just drop any unrecognized IR codes without hanging the system. However the fact that they have built in logging software and the talent to connect remotely and examine the logs suggests they have...

    Not a glowing report

    And essential in most rooms!

    Need help with Descent Subwoofer

    What about with receiver or preamp connected but turned OFF? Does the noise only start when you turn ON the receiver? Do you have a preamp or CD player with balanced outputs to try connecting to the sub XLR inputs?

    Need help with Descent Subwoofer

    What input on the sub are you using? This happened to me with another sub when accidentally connecting to the Xover input.

    ML Center Theater - Mod or upgrade

    Some people overtighten them with a wrench or nut driver (I see a lot of crushed or gouged spades on used speaker cables for sale). Finger tight should do it, otherwise the posts can break loose when reversing to remove the cables.

    DC Blocker

    PS Audio called them DC spikes? I think we may be confusing current with voltage here. DC offset is actually a constant voltage as discussed in the video. Perhaps they mean literally Direct Current which is current that a component in your system may be drawing unexpectedly. Does the P20 log...

    DC Blocker

    I mentioned that before DC offset is a very specific problem. Here’s a fun video from Paul @ PS Audio

    Any good media streamers coming out, or just released lately?

    Nice choice! I just bought a Bluesound Node 2i and getting curious about the NAD preamps. I hope it came with the BluOS streaming module because they’re discontinued.

    DC Blocker

    That’s right. Toroidal transformers don’t like DC and will vibrate at 60 Hz making an audible buzzing noise. They can also get magnetized long term reducing efficiency. Most tube amps use EI core transformers which are more tolerant of DC. Note that DC offset is not hard to find, and you can...

    Rogue Audio Atlas Magnum II

    It might just have less gain so keep cranking it up. I am certain you are hearing a more "pure" sound now, gone with the harshness and fatigue. I never heard the older Bryston-Lexicons but any of the Lexicon amps I have used could only be described as muscular and lush. I would expect the...

    New Anthem processors and receivers debut!

    Russ, I'm not so sure about that. The made in Canada AVM-50v (and Statement D2v of course) had incredibly well designed analog preamp stages. I have not heard the new ones but have been paying close attention to other folks in the Anthem owners groups that did upgrade. Word is that, Dolby...

    New Anthem processors and receivers debut!

    Alan, I have a pair of ML 1500X and an older Anthem prepro. I run ARC Genesis (was PBK) on the subs first, individually. I don't see why your BalancedForce subs would be any different. Do whatever it takes to get each sub performing optimally. I then switch microphones and run ARC on the...

    New Anthem processors and receivers debut!

    Better sound quality, ostensibly. I'm sorry that's subjective, but if Anthem published the list of every part that was "upgraded" or tolerance of "hand matched" parts, and you had access to the datasheets for the parts, would it help? Probably not. Subjective claims like that are about all...

    New Anthem processors and receivers debut!

    AVM90 is the new flagship with higher-end audio circuitry aimed at ex-D2 owners and audiophiles that won't be buying the STR preamp. https://www.anthemav.com/products-current/type=av-processor/model=avm-90/page=overview

    DC Blocker

    I agree. The transformer buzzing caused by DC offset is a mechanical vibration of the plates and has nothing to do with the sound coming out of your speakers. If you can't hear any buzzing when the preamp is muted then stop worrying about it.

    New Anthem processors and receivers debut!

    To add to what Nuri just wrote, the Anthem doesn't care if you're running ARC in the speakers as well. I run ARC/PBK on each sub first and then get them phase-aligned using ARC quickmeasure. If you have ESLs with ARC you would run it on them too. Finally run the full ARC in the preamp on...
