For insight into speaker design, I'm trying to get a concrete idea of the nature of Tridents' beneficial effects on B2 performance. Any ideas? Has anybody looked at waveforms? I would be really curious to see (or read about) a closeup of the leading corner of a 3kHz to 5kHz square wave looking for any differences with vs. without Tridents. My ears tell me they should be obviously different but who knows, it could just be a perceptual trick. I'd be curious about other frequencies as well. Anybody done anything like that or able to get that info without much trouble? TIA! [...my ferrites are long gone]

Is there any added value, beside galvanic isolation, to use a spdif transformer on input ? What does the data-sheet recommend ?

Thanks,

Davide

At the very first page, there is a tube IV stage mentioned. Any idea about the progress on this? Still waiting for the next pre-order

Speaking of tube stages, is it a viable option to try for current mode or do tubes equate to voltage mode by default seeing as how current mode requires a very low input impedance?

Follow-up question: Is voltage mode actually a bad thing? So what if the THD drops a little?

Do we have any successful BII builds with tube I/V stages?

Is it safe to connect an external controller with 5V logic level to the buffalo i2c interface or is 3.3V preferred?

1) Dustin told me that the interface pins on the ES9008 and ES9018 are 5V tolerant, but I have never tested it.

My Arduino builds are using 5V straights with no voltage converter and it works fine.

Cheers

Ok. Good to know someone has tried it. Would not want to be the first to try and find out it breaks the chip . The provided supply lines for i2c are 3.3V even though the dac board is fed with 5-5.5V, so I thought the i2c inputs might not handle higher voltage.
