Ship my Bifrost!!!! I NEED my 128 Bits!

How complicated would it be to add a 4 way touch pad and screen that reads out text?

Complicated enough that smart men like Jason and @Baldr refuse to touch it.

So considering I'm working with lower than average intelligence on my end, how many man hours of work?

How about jack up the case and put a new design in it?

Don't mix'em up or both units will explode.

Instructions unclear...I cut the one that had the red wire and now my tubes are no longer glowing.

Interesting - thanks for sharing! Where did you get the resistors and what resistor values did you use? Also, how does the Ragnarok 2 sound with the Zus?

I like Rag 2 and the Zu, but I also like Rag with my LRSs and KLH Kendalls. (I really really like my Ragnarok)

Unless you listen to classical music. Or has that changed?

It has improved!

Geez, did they even make any before the announcement??

No the phots are illusions........

 

[golfbravobravo]

You must be really old to remember DOS commands.

Some of us remember (well, I use the word advisedly) Z80 assembler.......

Depends on how you respond. My wife asked me if her new jeans made her look Ex-FAT, and I plead the 5th. That didn't work well.

You got what you deserved.........

There's been some discussion about mobile/offline play getting into their roadmap, but nothing has been announced so far. It would be nice!

I just have Plex (in addition to Roon) look at my audio files on a NAS then use Plexamp on the phone.

Hmm. Different strokes and all that. For me, if an amp doesn't perform well with a given load, it's the wrong amp for the job. I see no sense in wasting power to heat resistors.

Well....
If you are running multi-way speakers, you may find resistors in the cross-over---perhaps to match levels from the different drivers, or for baffle step correction. (BSC should be covered in speaker design books, but you might look at Martin King's web site for a bit about them: http://www.quarter-wave.com/General/General_Articles.html )

How-some-ever, placing a simple resistor either in series or parallel on the input to your speaker will affect the response. Speaker systems (even single drivers) are not simple, resistive loads. Just take a look at the measurements section of one of Stereophile's speaker reviews: https://www.stereophile.com/content/q-acoustics-concept-50-loudspeaker-measurements . R vs, freq. may well vary from, say, 4 to 50 ohms over its frequency range! And the impedance combined with phase angle can sometimes be problematic for some amplifiers! It's no wonder that we end up searching for synergy! (Consider the discussion of how various headphones perform with FV.)

Cheers, Jim

But we're not talking about resistors in the crossover where they're equalizing loudness levels between different drivers or doing eq work (zobels, bsc, etc.). We're talking about resistors in parallel or series or both (wasn't originally mentioned how they were used) with the entire speaker. So the person is either reducing the power going to the speaker (by dumping it in a resistor) or dampening the load the amp sees to reduce strain on the amp. Either way, my opinion (again), wrong amp for speaker.

More than is worth devoting. Ask the software folks on this forum about getting things just exactly perfect.

I'm torn. I like a repository of measurements on the web, like Stereophile's and this. OTOH, the guy himself apparently doesn't know how to do measurements correctly. Can one draw conclusions comparing things that have all been measured incorrectly? I'm not sure he does it incorrectly consistently, iykwim.

But his acolytes, omg, they need to get a life. A dunking in a shark tank would be a more pleasant experience than expressing a different opinion than that expressed in the review.

His acolytes are a lot like Elon's fanbois. Just please - whatever you do - don't lump Amir in with John Atkinson of Stereophile. While Amir might think he's on the same level as John, there's no comparison. https://www.stereophile.com/content/john-atkinson-receive-laocas-founders-award
