Re: Nearfield monitors

The Sounds Sweet comm speaker isn't a monitor per se but does a good job for me when compared to the built in speakers I've used. Its big, about a cubic foot, but plays plenty loud and clean, albeit somewhat mellow. About $180 delivered 30 day satisfaction guarantee.

I wish I could get the old Uath Alnico drivers today!

Obviously an attempt to copy the name, look and style of what was considered the worst TV speaker in the world, the Auratone. When will it stop.

I highly recommend these:

http://www.audioadvisor.com/prodinfo.asp?number=AQNRG10

They are so effective at RFI suppression you can use any old cheap
switcher supply
without worries.

I'd suspect they will also help with the new peak current demands of the
eagerly anticipated
APF.

I would really like to see the sales figures for these. How many *'s
are out there?

After reading what you wrote about the expensive hi-fi speakers you (own) and tested on your K3 I new you were one of those guys easily fooled into buying those expensive "home theater cables", and you just confirmed it! I'm a Monster wire dealer, and I have to tell you Don, we have a 400% mark up on that wire. I laugh every time I sell a cable to someone and make $60 on a 12' piece of wire stuffed into a over sized plastic jacket. Thank god for people like you... I can still make a living during "home" installs.. LOL
Wire is wire, 12 awg is 12 awg, no matter what kind of plastic casing is melted around it... Ohms law... LOL.

Sure. But those large diameter wires that are part of exotic cables also
come with a huge markup, justified only by the marketing gobledegook.
These mechanical issues are their only advantage, but sometimes that's
important. Good engineers view them as simply another alternative,
taking their cost into account. There are, for example, some very wide
flat two-conductor cables, sort of like flex circuit packs, that are
built so that they can be run under carpet. They would NOT be good from
an RFI point of view though, because they're not twisted. :)

#12 stranded copper is $0.10/ft in 500 ft lengths at your friendly Home
Depot. Probably less than double that in 50 ft lengths. Even paired
house wire or flexible AC extension cords are a jacket is a good cheap
alternative. You can also reduce the resistance by putting the green
wire (ground) in parallel with one of the other conductors. Just be sure
to cut off the AC connectors -- some rather smoke could be released from
speakers or amplifiers if someone plugged that cable into a 120V outlet
by mistake. :)

Funny story, sort of. About 15 years ago, some fool bought a booth at
an AES convention to promote a product he called J-Conn or something
like that. The product was simply a set of adapters to convert from AC
plugs and sockets to speaker connectors. Throughout the convention,
many engineers descended upon their booth to tell them how stupid and
dangerous that was.

The issue is NOT power, but rather damping factor. If the resistance is
high, the transient response of the loudspeaker can be degraded, so the
low end sounds sloppy.

Re: Nearfield monitors

You're crazy if you don't buy this stuff... I'm telling you, if you want good sound out of your K3, you NEED this:

http://www.audioadvisor.com/prodinfo.asp?number=AQK2

You'll need this one for your sub woofer.. No need to get 2 pair wire for that:
http://www.audioadvisor.com/prodinfo.asp?number=AQNIAG

Or if you're a cheap SOB you can just use this junky stuff:

http://www.audioadvisor.com/prodinfo.asp?number=AQCV8

http://www.audioadvisor.com/prodinfo.asp?number=AQCOLO

Also, since you're working on the K3, you may consider hooking up your KUSB with one of these:

http://www.audioadvisor.com/prodinfo.asp?number=AQUSBCOF

DO THE RIGHT THING!

Re: Nearfield monitors

In reply to this post by The Smiths

Not exactly - for instance, I did not purchase Monster Cable because
it was exorbitantly priced, but I found a less expensive alternative
that was just as flexible.

Everything has its value to those of us who make the choices of what to
purchase. Prior to purchasing my audio gear, I have done exhaustive
comparative listening tests to select the gear that would suit my ears
and my budget at the time. There is advertising hype, and then there is
good science, and then there is what I can perceive with my ears, and
then there is my budget for such things - all have to balance before I
make a purchase decision.

It says right on the web page that this is the K2 model. The K3 version is presumably more expensive.

None of that cheap Monster stuff!!

Bob, Et Al,

Just a note: I had one switching supply that radiated from the box
(lots of nice birdies spaced about 100K IIRC)... I can't imagine any
grounding that would have prevented that... {'-)
