    Seattle Meet Saturday Sept, 7

    email sent with long story. Short story here: after leaking in-wall pipe water damage, lab restoration is now complete, 4 months and $20K later. Hope to see you at meet and hear your big iron tube amp project.

    Seattle Meet Saturday Sept, 7

    Anyone interested in hearing Schiit Bifrost MB 2 and ECP Audio T4 with Mullard CV4024 tubes to an HD800J-mod?

    Monoprice Monolith Liquid Platinum - By Alex Cavalli

    Let me get this straight. Someone can afford an APx555 analyzer and then doesn't take the minimal extra step of constructing a Neutrik NC4MX breakout cable for 30R and 300R loading of each channel with other side of resistor loads having cable to pair of NC3MXX to plug into the analyzer balanced...

    Schiit SYS Passive Preamp

    It has become popular to reverse a 2-input passive attenuator to switch between two outputs. While not exactly recommended, as long as the potentiometer is set to maximum and left at that position the source will only see the additional load of the pot, which is usually between 10K to 100K. The...

    3/03/19 Seattle Lake City impressions

    Big thank-you to @BIG POPPA for organizing another successful meet. I was surprised with a gift from several of the regulars; a power distribution box with three duplex outlets, each using a different metal. High purity copper, rhodium, and cryo treated silver. Also has an on-board voltmeter...

    Goldpoint SA2X - Nobsound NS-05P passive attenuator comparison technical measurements

    I believe I already addressed your question in posts 1 and 8 above:

    Monoprice Monolith Liquid Platinum - By Alex Cavalli

    Until that time I suggest everyone consider a new paradigm with Liquid Platinum. The LP has exceptionally low distortion and square wave response is nearly that of the Liquid Crimson; almost perfect. This great clarity translates to hearing and differentiating source components at a level few...

    Monoprice Monolith Liquid Platinum - By Alex Cavalli

    Schiit Sys will measure better than NS-05P when attenuation is between 1 and 20 dB. NS-05P has advantages of balanced inputs and outputs. If intended for balanced use with 20dB or greater attenuation, then NS-05P has advantages. Whether all this means either will sound better than the other...

    Monoprice Monolith Liquid Platinum - By Alex Cavalli

    The big issue with NS-05P is use of a 50K pot instead of 10K. High end roll off issues would be eliminated if Nobsound changed the Alps to a 10K pot. Schiit Sys uses a 10K pot. All passive attenuator pots have imbalance issues at high attenuation. Stepped attenuators are the way to eliminate...

    Goldpoint SA2X - Nobsound NS-05P passive attenuator comparison technical measurements

    1. Will you use less than 20 dB of attenuation? 2. Can you hear -1 dB at 10KHz? 3. Do you care about channel imbalance at high attenuation? If yes to #1 and #2, then you will likely hear the NS-05P to rolling off highs between 1 and 20 dB attenuation. If yes to #3 then low volumes will change...

    Here is a link to measurements I made comparing two passive attenuators of which I used with Liquid Platinum (and other amps): https://www.head-fi.org/threads/goldpoint-sa2x-nobsound-ns-05p-passive-attenuator-comparison-technical-measurements.899382/

    Goldpoint SA2X - Nobsound NS-05P passive attenuator comparison technical measurements

    Frequency Response vs Attenuation 42 dB Attenuation - Belden 1800F cable 2 ft SA2X (blue) NS-05P (red) performance is essentially identical out to 40 KHz 36 dB Attenuation - Belden 1800F cable 2 ft SA2X (blue) NS-05P (red) performance is essentially identical out to 20 KHz 24 dB...
