I have Klipsch cf3's. I listened to classical large orchestral. I am wondering if this amp can produce the dynamics oflarge orchestral. Does the amp have any of the upgrades listed on Bottleheads page? Thanks Bob

I would lean toward true SET using 45's, 2A3's, or 300B's. They should work well with K-horns

My CF-3's are serial #'s 241599265 & 241599266, I assume they are the 241 week of 1995, correct? Making them version 3?

Sorry, Klipsch CF-3, version 3, I believe

At some point do crossovers require rebuilding? If so how do you know.....judge by sound?

Hi everyone, been reading this post ...... very interesting, brings to mind some questions. I currently have CF-3's that I have owned since I bought them new. I have been looking at the 'little brother' to the TORII MK4, the TORII JR, from what I read on the Decware site very similar "The JR is using the same proven if not legendary circuit used in the TORII MK4 but stripped of all non-essential features" (from the Decware site). Could I face the same potential issues with the CF's? I was not aware that Klipsch used autoformers, are they the same as the Paul Speltz products? Given the age of my speakers is a crossover upgrade/rebuild necessary?

I have CF-3 version 3's in walnut that I bought new. I let my daughter use them for a while and now have them back. Have not personally heard version 1's, the opinion I have heard on this forum is the 1's are better but by how much I don't know. I do know that they were a variation from the typical Klipsch design at that time.

how much difference can be heard between the versions, especially between versions 1 and 3? Thanks Bob

Shiva, What are class T amps?

Moray, Interesting, I have asked a few people about the CF's efficiency and most said they felt it was slightly overrated for instance CF-3 more like 95 as opposed to 100 as stated. The other lines such as Heritage I believe may be as you say, but this is just what I have read. WVU80, Have listen to a tube amp, some people prefer the sound......I do, but everyone has different taste Bob

I am guessing I am border line for using a SET, if I find a inexpensive used piece I will try it or if there is dealer by(which I don't know of) that I can demo one otherwise I will most likely demo a Prima Luna integrated (I know there is a dealer by me) . The Prima Luna is interesting as you can switch between ultra-linear and triode mode, it is also auto bias

I should have also said my listening room is about 12'x20' and I listen to classical especially large orchestral. I am guessing <10w may be ok for chamber but would need >10w for the larger orchestral

I have CF-3's, according to Klipsch they are stated as being "sensitivity 100db SPL @ 1 Watt/Meter". I read somewhere this may be a little overstated actually being a bit lower. The reason I ask is I looking for a new amp and if it is actually lower it would most likely rule SET. Thanks Bob

Anyone have experience with Prima Luna? I am thinking about one of their integrated 's fro my CF-3's, the adaptive auto bias seems like a positive feature. I am also considering a true SET say 45,2a3,300b. I know the power difference is huge, would the SET work with the CF-3? Thanks Bob

OK, thanks, the reason I posted here is because I would be using the amp with CF-3 version 3. Have any amp suggestions. I have a 12'x20' listening room and am about 15' from the speakers Bob

Hi, Anyone tried or have experience with Prima Luna integrated amps? Bob

I now live in Moose Lake, I lived in Minneapolis until 2002. In addition to HI-Fi Sound and Stereoland, are Audio Perfection, The Needle Doctor(Jerry Raskins), Halsten Entertainment. There is also Audio by Van Alstine, who manufactures his own and sells direct (he will audition equip). I have bought equip from Hi-Fi sound and Audio Perfection. I believe Halsten is geared more to home theater. Van Alstine has interesting gear, here is a link https://avahifi.com/

I also think the Epics can be demanding on amps, as their impedance has been shown to dip below 3 ohms. I do not think tube amps would like impedance dipping to 3 ohms. I am leaning towards the Rogue Sphinx because there is dealer near and I think I could bring the rogue home to demo, also it's only about $1300( I am in Minnesota, even in Minneapolis there are only a few high end shops) But I am intrigued by SET

What you said reminds me of what someone once said that the CF"s like lots of power. I hear what you are saying about try different gear but that can cost alot of money unless you find inexpensive gear used. I used mine with a Yamaha AX-570 and a George Wright main amp that was a 6550 push pull amp, I noticed the bass was tighter on the yamaha but the mids better with tube

Hi, Please excuse me for changing the topic, I would appreciate input. I would like to buy another amp (integrated) for my CF-3's (version 3 I believe), I have a couple of questions; I see according to Klipsch brochure they are rated for 100 db SPL sensitivity, I think I remember reading on a forum somewhere that this may too high and it may actually be in the mid 90's? I know they are nominally rated at 8 ohms impedance, but a told the impedance curve is not very flat and that in general tube amps prefer a more flat curve? I am considering a Rogue Sphinx integrated which is a hybrid or a fully tube integrated like maybe a Decware low power. Some have told me I may be fine with under 10 watts per channel. I listen to classical and especially like large orchestral, my concern with the low power tube would be having enough power for this. At one point I tried the CF-3's with a older Yamaha AX-570(100wpc) and a Geroge Wright tube pre-amp, it sounded good but pre amp had too much gain for the main amp, plus the yamaha is older. This is why I am considering the Rogue. Another question is do solid state amps in general have better damping factors than tube? In my mind this relates to woofer control which the CF-3"s have 2 - 10" woofers. I am interested in the Decware or similar but want to make sure I have enough power Thanks Bob

This is the reason I went with 3 separate amps, this way, I can control what I want when I want. I toyed with getting a Scotts, until I heard what a SET can do, what a SEP can do, and what a PP Integrated can do. And none of my amps ran more than $500.00. I know there's much much better out there, but for where I'm at in the game, they keep me happy. If you can find a cheap Chinese Class A SET, you can get them wired already in triode mode and pushing 4 WPC. It will give you that nice 3D imaging, then all you need to do is "upgrade" the caps and resistors if anything. I had my SET upgraded for less than $175.00. I know you are going the other way due to your room size, but if you wanted something for critical listening, here's an idea. Try looking at one that puts out slightly more power and only has one input. Jim, Your comment about one input is what I may try to, I have have one source my CDP and do not plan on any others. The other interest would be integrated for simplicicty

I agree outstanding

Thanks Matt, from what I have been able to find these speakers are most likely not very linear. Given our chat here your Genesis would most likely be a bit small, what is the power output of your other unit again? I appreciate all of your help, I just want to make a good choice. Thanks Bob

Thanks Maynard, I kind of guessed that I was just providing the info for curiosity or?

Klipsch states 100 db SPL, I have hear some suggest it may actually be as low as 94. Please define EDM To clarify when we talk about amp power are we talking 9 watts per channel or 9 watts both channels combined. My readings were done with a Yamaha AX570 100WPC, the volume control was a bit above 9 o'clock Bob
