BTW, Craig, I cannot get that ideal 10 volt difference on this Fisher console bias, anywhere on that pot. I haven't yet measured other pin voltages.----------------

What have you been able to get? I'm sure you realize were guessing at this.

mark, it depends on your target market right? I would be in seventh heaven with 20watss and would not want more BUT most other speaker owners would want the upper end of the spectrum. it also would depend on the differences in each amp what would the 20watt sound like versus the 75watt? difference in tube life? regards, tony

My input should be considered casual. I'm interested but purchase is not likely in the present season, just paying attention to finances and reluctantly acting like a grown up.

For my power needs driving Khorns, 20wpc would be headroom aplenty. It's a head scratcher for me to contemplate folks who really consider that power indadequate. But, hey, whatever floats your boat is no problem to me. I think that my preferences are the minority report, but don't really have an idea about how market preferences would break out in real terms. d

I've been hoping that someone will have purchased pCAT's by the time of the Klipsch gathering in Indy, or wherever, and kindly bring them on the trip.

I knew it! I just knew it!....It's Porno, with some American chick dressed like an Acasia girl...your a sick man fini.

What time can I come over?

Mark...in responce to your question concerning which amp's to produce first. I have 2 questions. Of the 3 flavors offered, do you have a personal favorite?....that's the one you introduce first.

2nd question, it's my understanding (someone please correct me if I've misinterpreted what I've been reading hear these past few years) that tube people and efficient speakers go together like the apple in apple pie....So, why the need for a 75w.

BTW, although not 100% confirmed through thorough testing, all the pCATs are expected to sound the same - as I explained above. Not identical mind you, but of "such similar character" that it would be hard to tell one from the other. My concept is that only the power changes.

Hence, the "Juicy Music Sound," right?1.gif

Craig,

Yes, I know we're guessing, with no schematic and all. I am very comfortable with that. I'm enjoying the learning experience. I wrote the voltages down somewhere (can't seem to recall where), but I will get 'em again.

Gilbert,

You're welcome anytime. Just knock on the coffin lid...

Ummm, there's an interesting thought. When is that thing? Boy, if it was possible, I'd love to bring some pCATs in person to that shindig.

Mark,

Most likely in late June. Keep your eyes on the Klipsch Pilgrimage 2005 thread in the General. Trey indicated he'd have a firm date and location for us next week.

On the pCAT, I'd say 40W or 75W for my preference.

Mark,

Right now I'm running a pair of MC225's with the Peach to my Cornwall's. Considering that McIntosh supposedly rates the power output of their amps very conservativly, I guess I'm getting 55+ watts per side. With that in mind, I wouldn't want 20 watts, 40 watts would be ok and anything over 50 would be my choice. I've tried (all per side) 1.5 watts (Decware Zen), 13 watts SE (Cary), 15 watts PP (Brenneman), 20 watts PP (Scott 299), 25 watts PP (Scott 299B, MC225), 30 watts PP (ARC Classic 60), 50 watts (MC225 pair) and a few SS amps. With every amp I've tried, there seems to be an area in the volume control where the sound is the best. If I go too low, something seems to be missing. When I get past the "sweet spot" area, the amps seem to be working too hard.

Chris

PS I've traded a few emails with a guy supposedly looking to buy a Peach. He seems very interested in remote control operation. Sounds like he's ready to order one.

For those who might have some interest in pCAT somewhere down the road should I focus on building 20W, 40W or 75W model? I can't do them all at once, in other words. Even casual input is valuable - thanks.

Mark,

I don't know the guy that emailed me regarding my impressions of the Peach. I'm not even sure how he got my email address. He did mention installing a remote himself after purchase from you. BTW, I'm just fine turning the volume control knob on the Peach instead of pushing a button on a remote control...even if that means getting up off the couch and walking alllll the way to the audio rack. Whew! I get tired just thinking about it! Are we a lazy society or what?

Chris

----------------

P.S. Remind your friend we have no remote control. If I did have remote, I would have sold 500 Peaches by now. I get more email questions about remote control than anything thing else by a 20:1 margin. In some sense it feels like no one cares anything about sound, just remote!

Mark -- I just want to toss something out to think about: My VAC has a selector knob to adjust feedback. The settings are 0db, 1db, 2db, 4db, and 6db. At the lower volume levels, zero feedback sounds best. As I increase volume, the midrange begins to dominate, and the system doesn't sound as balanced. After a lot of fiddling with the settings, I began to realize that I always got the best sound if I added feedback as I increased volume. It might sound stupid, but I've divided up my volume control settings to correspond with the feedback settings. At the 8 o'clock or so position (with The Peach gain controls set at 12 o'clock) I switch to the 1db setting. At 9 I go to 2, at 10 to 4, and at 12 to 6. This crazy procedure works, and no matter what volume level I choose, I can always dial in the perfect sound with a click of the feedback knob. At this stage in the game, it would be very difficult to part with this flexibility. Thoughts?

Actually, after mulling over all the possible fruit names, I just didn't find any of them felt suitable for a POWER amplifier. They didn't seem to communicate power to me. The idea of the large CATs like tigers and panthers had a more palpable resonance - the "beast" under the hood sort of thing. Who knows? It's just an intuition on my part - purrring engines - that kind of thing.

The Kumquats are coming? Just didn't ring my bell.

Beans are a powerful fruit, no? and I think, as such,they even have some sonic implications....never mind....we won't go there.....Bean Powered Pentodes.......

The Ford Pinto doesn't necessarily make you think of power either, now that I think of it......kidneys, limas, navy, ....nothing....not exactly elegant names for amps....

Man, I never expected that this fruit thing would break down....and so soon.....I thought it could have gone on forever....but I see your point......

Sometimes you just want Meat and Potatoes, not Pomegranates and Kiwis....

Never met a CAT that didn't like Cantaloupe though for some reason, ever notice that? But who would make that connection? You would be wasting alot of time explaining that Tigers crave Cantaloupe.

OK, you know what you are doing.....I cannot help here.

C&S
