WoodShed Changes

Can't wait to check it out big poppa. The little PS Audio can't handle (and frankly isn't designed for) a man amp like that, period. Honestly, unless you need conditioning and/or filtering - I'd go with basic surge only or nothing at all on the amp.

Get a good outlet - PS Audio, Porterhouse Audio, etc etc - matching power cord, and plug it RIGHT in the wall. (keep an eye on the weather radar daily) If you need basic surge, Furman, Nady, Triplite (and others) make basic, no frills surge protection - without limits on the current draw.

Not sure where you came up with that, but it's not true.



Straight from PS Audio....

"The UPC 200 provides unrestricted power, in either two or one zone operation and can be used for even the biggest power amplifiers"

"The typical home in the US has 15 amp receptacles that can deliver up to 1800 watts. The UPC-200 can take advantage of all the power available from your home's receptacle as there are two modules inside, each capable of passing up to 20 amps of unrestricted power."


Using the average ratio of one watt is equal to 65% of one volt-amp (VA) and with the BAT rated at 2000 VA at full power, the maximum draw of the amp would be 1300 watts at full power. Actually, I believe it's rated at 1250 watts at full power on the back panel, so about a 63% ratio. Even if the ratio was 90%, which is highly unlikely, the maximum draw would be 1800 watts, still within the capabilities of the UPC-200.

I did call PS Audio and asked them about it, then I wrote them, got the same response both times, in a nutshell, they said for my application I should use a seperate UPC-200 switched to high current for each side of the VK-500. Of course they are in the business of selling the units but that is what they said.

Balanced Audio recommends the Shunyata, actually the Hydra, but then they always recommend high end stuff for their stuff. hmmmmmmmmmmm. My new Russian buddy at BAT, Vladimir Shutnov says.....you neeeed thirty amp line for VK-500......is very powerful amp........you run balanced.......one kilowatt per side amperage changes moves up and down.....you hear meeeeeee. waaaaaaaa

I am going to put the high end outlets in the new Shed, it has a dedicated 20 amp line, the existing Shed is using 15 amp. Right now running the amp straight from the wall, things sound good, I will see what happens with the Shunyanta Guardian when I do the in home demo.

Sounds like Burmester, 30 amp line? Wow.

Not putting down the PS Audio, it seems like a perfect solution for the front end, or digital section of a rig. Probably works great for most amplifiers, but your BAT is an entirely different league. If I were a betting man, unless you get a balanced power supply, my money is on the wall sounding better than any conditioner will for you application.

Chuck,
The room is 11'6" x 14 x 8'. The speaks need to go on the 11'6" wall, which has a door opening onto it.

Bruce,
....just keep those Plats warmed up.
I guess I will sell one set of the Amazings, but who knows??

No problemo, senior Poppy. Still running them about 17 / 7.

Just for S&G's, before the Plat's leave here I'm going to set my originals up with yours. Will criss-cross one pair so the ribbons are next to each other for both channels. If the sensitivities are close, it ought to be interesting. Hearing protection may be required...

max,
My comment was more around imaging than SQ. Since the ribbons throw all the localizable FR, the ribbons need a bit a room 'tween 'em. Thus the ribbons to the outside approach. But get the ribbons too close to the side walls and reflections of the sound originating on the backside gets funneled.

That said, CA's can most certainly work in a smallish room. I heard Troy's in his smallish "cave", and they did just fine. But he had them on the room's "long" wall and could manage a good 6' or so between the ribbons.

doro's were on the short wall of his sound room, and the ribbons were only 3 to 4' apart. Sounded good, but the image was congested. We should have swapped them, but we both enjoyed my introduction to Knob Creek a bit too much to engage in manual labor.

I had mine in a big room once (30x35 or so) and found them wanting to be within about 3' of each other. Never tried anywhere else except a very small room of maybe 8' x 12'. They wouldn't do anything in that size room.

Dunno... My den is ~21 x 15 with multiple openings and they fill the whole house with sound... even if not cranked.

I know we've discussed this before, but after I did some checking and finding out that the BAT is rated at 2000 VA (1250 watts) max, the recommendations don't add up. I know we thought the BAT was 1250 watts per side, but that's not the case, so a single UPC-200 should work just fine and the Hydra, being rated at 2400 watts max, won't pass 30 amps anyway. Considering that you're running it on a 15 amp line right now and all is well should confirm the facts above. Of course, a dedicated 20 amp line is always a good move.

Bruce - Just for the record, you are not allowed to touch anything in regards to my stereo rig. This has been written in stone since the TX Polkfest.

I have the strange feeling some other hardcore Polkies may have the same commandment.

How far apart did they want to be in that size room?

Tour2ma

7' ribbon to ribbon. And although the manual says parallel to the wall, ended up with a very slight toe-in. Center of speaker top is ~12" from back wall which is very lively wood paneling. Listening position is ~10'.

... and by that you mean the "other" hardcore non-Polkie... (AKA your evil twin)...

OK, who had doro and 12:22 PM in the pool?

EDIT: Mark, when you say "touch" you're talking hands? Yes?

Very strange speakers. They seem to vary massively on setup. When I got more than a few feet apart they lost their soundstage in the big room. Mine were about 3' apart and did require toe in. Thanks for the info!

Btw, never touch others equipment under any circumstances. :eek:

Let's just say if I ever catch you naked in my basement again, we're done

All right, after everyone gets their pants back on, zippered up and so on, place things back where you found them and Please clean up any mess you might of made, dropped or otherwise inflicted upon the Shed.

BTW--Just remember and hold this thought, my body parts likely touched everything before you did!!;)

When you moved it from between the speakers where did you put it that it would cause less vibrations?

I purposely placed my gear between the 1.2tls because I thought that anywhere else in the room would be too much vibration because of the direct projection of sound from the speakers anywhere in front of them.

Back in the day I placed the rack on the wall directly across from the speakers but in the room behind it.

That is an awesome rig I can't wait to experience it this fall.

Okay, go ahead and ignore the retards questions!!!:eek:

Audio Geeks, HI wait till you meet DJ7, gonna be a match made in heaven....I love you guys, really I do:D

Joe, I moved it to a side wall, when I give the table a little finger now, I do not feel it vibrate as much, of course this could be said of many things I might finger......:eek:

I did not hook a seismonitor up to it though, either of you two have one?????

DJ7 what are my pants off again :eek: :rolleyes: :cool:

tonyb

Very nice.....was kinda wondering.....about your definition of a "woodshed".:D

disneyjoe7

Well it started like this....


Ted, put an audio room together where he spent time there listening to tunes. He would leave that room returning to the rest of house where he would see his wife, then it was obvious Ted had a Woodie. There you have it WoodShed.

tonyb

LOL!! But....when DOESN'T Ted have a woody??:p

The sensitivities are NOT close. The originals are 84db/1M and the Plats are 89.

If Big Daddy is going to unload a pair of CA's some of you might want to think about saving some pennies.

The difference in sensitivity and the one ribbon per speak are the reasons I just had to get these, I can only imagine, (with wood), how they might sound with the Shed gear.

Under the FWIW dept, I am demoing a power piece with the BAT amp which I really did not expect to much from..................stay tuned
