Joe, Remember patience is a virtue (now if only I could follow that advice) Great Signature! maybe it will catch on around here! Jack

C'mon over to Knoxville and you can hear the MC-2102 and the Jubes!! Just be prepared to go home & explain to the wife why the Khorns gotta go [] LOL! Trust me the Khorns would stay. I would be the one to go! In her eyes it would be cheaper []

Mike, Maybe I have had McIntosh for too many years. I was impressed with them at a young age and come to think of it never really tried anything else (first impressions you know) I have never had anything but McIntosh (several different models) on my Khorns, Belles or Heresy's. I had McIntosh before I had Klipsch. Come to think of it for two channel listening I have had Mac since 1969 when I bought my MC240. I do have Anthem (Sonic Frontiers) amps on my Home Theater System but have never hooked my Khorns to them. I too would like to hear a comaprison of other tube amps with my MC240 Jack

Dr. Who So why don't you tell us what you think is a good amp So why don't you tell us what you think are good speakers So why don't you tell us what is your type of music

There has been some very good advise given the limited amount of detail you provided. What did you have before? can you elaborate on what you mean by "harsh?" I have never heard the MC275 re-issue, but have read here and there they sound nothing like the original, not to say that is good or bad. That is a lot of cash to fork out on unknown sound. Do you have a nearby McIntosh dealer you can go listen to several different Mac amps (altho I doubt they will have a pair of Khorns)

Rob, I'll be looking forward to see the finished project (wish I could hear) Your old 97's have setteld in nicely, going to be doing a little experimenting in the next couple weeks, tri-amped w/Altec 511b's. just to see what the results are Jack P.S. Sorry for hi-jacking the thread, now to return to your normally scheduled broadcast

Hiya Rob! What ya got in that top hat? Jack

These adapters are what was recommended to me from several people here on the forum. I don't know what the material is as I haven't received mine yet. but if it is plastic, i don't think it will affect the sound quality

your ps first... Yes Parts Express, part # 264-322 Selenium ADF25-25 Horn Lens Adapter $6.50 ea I should have mine next tuesday, I just got my horns today I am not exactly sure what the technical aspects are with the autoformers. Where other SS amps just have + and - speaker terminals, the autoformer'd Macs have impedance taps like a tube amp (4,8,16), and they are strappable (able to run as a mono amp at twice the power) An MC2100 is 105wpc at all impedance taps, whereas a non autoformer'd mac the rated power fluctuates with impedance. I personally own 8 of the autoformer'd guys (5 mc50's (50 watt monoblocks) an mc250, an MC2100 and an MC7300, a MC6100 (non autoformer integrated) an an MC240 Tube I highly recommend the Mac SS as a viable alternative to tubes (autoformer'd that is) Jack

WOT, Yes the MC2100 is solid state, I have several of the Mac SS amps and also Mac tubes, I would like to say one thing, the Mac SS that have autoformers fall into their own category. I also have a Mac SS without autoformers, the autoformers place the amp "in the middle" for lack of a better term. Not quite "tubey" but not "SS" either. I am extremely happy with my autoformer Macs. I currently have my Khorns w/Belle center and Heresy rears all Mac SS. In the next week or so I will be doing an experiment tri-amping my Khorns. Mac SS on the bottom, Mac tubes for the mids and either Mac SS or modified ST70 for the highs, should prove to be interesting. But then I will also be trying a pair of 511b's for the mids as well. Lots of playing to do in the upcoming weeks.

The MC2100 is just an amp, well not just an amp, a very fine amp, however to use multiple sources you should have a preamp. it does have volume controls but individual vol controls is cumbersome and only one set of inputs. I have a MC2100 along with several other mac amps I really like them. Definately more than enough for a pair of Khorns. They are clean and have autoformers Jack

Jackpod, A piece of advise...... many have traveled the road your now on. All have been lost in the endless round-abouts. Take the path with the quickest striaght path to you destination. Now if I could only learn to take this advise myself [] Craig Craig, I hear ya... I kinda remember back when i thought it was necessary to prove myself to the world. I am past that point (long time ago), no need for me to piss on the wall, I have already made my mark (many times over) how's the old saying go... Young, Dumb and well you know the rest... Some of the hardest but best learned lessons in my youth were from some old farts slapping me down. The kid appears to have the potential to go a long way, he just has to learn how to get there. Subject closed...[]

If you only had a clue, maybe in another 20 years. I hope you had fun insulting all the members here who like 50 year old technology, and insulting all the great audio pioneers who didn't have computerized analysis tools or the Internet to get their info from. I never claimed to be better than anyone, just that I do have a lot of experience and since you did not expereince audio of the 60's, or 70's or 80's and a good part of the 90's I really don't think you have much to stand on. Have a nice day Mike, I hope you continue to enjoy trying to baffle the people here with bullshit

Thats the funniest thing I have heard in years. I see you have taken your birthday off of your profile, but if memory serves me correctly you are like 22 years old. How can you make a statement that you have 14 years experience? So you started in the trade at 8 years old?, I am laughing so hard I might have a coronary. I am 55 years old, I played music professionally for 20 years as well as did pro sound for many big name bands in the San Francisco Area, owned my own studio in the 70's, bought my first McIntosh in 1969 (which I still have in absolutely mint condition). I am probably older than your parents. Now lets see if I said I started when I was 15 (which is when I formed my first band), that is still twice your age in my experience. So I guess I will compare the ludicracy of your 14 year experience statement and apply that to everything else you have to say... Thanks for the laugh, I have tears in my eyes

Sure wish you guys lived a little further south west. I would like to pick up a second pair of Khorns... but in the meantime, Fedex just delivered my (new to me) 511b's now to wait for the adapters from parts express... Jack

gazillion ditto... Some of their support people are from the McIntosh factory. I've dealt with them a lot (only with McIntosh gear tho) I can't imagine their practices changing with other manufacturers. A bit pricey, but you get what you pay for Jack

Dr. Who, I am not going to get into this with you. I never said anything about an equalizer. Just because you happen to be a master at search engines and obviously read a tremedous amount does not make up for the many years of experience that some of us do have. So you go on ahead and believe what you read and believe that all practices and procedures prior to the last couple of years didn't work. I wonder then why so many of us prefer technology and designs some 50 years old. Have a nice day!

Jackpod, I think you missed all of my points, but that's ok. A spectrum analyzer is not the correct tool. You need to use something like a TEF that can measure the direct sound and reflected sound independantly of each other. You can then compare tonal balance between the direct and reflected sound and ensure that the tonal balance remains constant - regardless of the timbre of the direct sound. In other words, you only remove boominess or pingyness if it's the result of the room - not the result of the source material. It most certainly doesn't require a perfect world. Dr. Who, Maybe today with such tools available as a TEF, which is a new technology and was not available just a few years ago. Spectrum analyzers and pink noise (not source material) were used for many years. Used properly and having the experience to know what to do with the results a simple spl meter and oscillator can also be used to tune a room.

And also I would like to clarify "spectrum analyzer" I am not making reference to a mic plugged into a laptop soundcard. Average computer sound cards are far from being calibrated or flat. I own both an Audiocontrol Model C101 and a McIntosh AA2, with calibrated mics. I have seen the differences

A point that no one has mentioned, and maybe just automatically assumed is how is it going to be determined where the room deficiencies are and what acoustical treatments are going to be applied. Not everyone has high priced spectrum analyzers. If the tests are going to be done with a test cd and an SPL meter, upstream equipment CAN make a difference. If the current electronics have a bright top end and you treat the room accordingly, any future electronics that have a more mellow top end will be further "mellowed" because the room treatments are absorbing more than if the treatments were applied using the latter electronics, same applies in reverse and well as low end and midrange. Now if you are fortunate to have a nice pricey spectrum analyzer with known response curves, sure then the room can be treated and almost anything will sound good in there. Unfortunately this is not a perfect world, so "perfect world" anologies don't always apply.

I might be missing something here, but which comes first the chicken or the egg? How are you going to tune the room without the equipment and if you use equipment other than what will end up there, will the room be tuned appropiately for the equipment that is not there yet? Back on amp topic, you could easily obtain a pair of McIntosh MC250 (run them in mono) for under a grand, Solid State, with autoformers, but sound really nice with Khorns

Cool! Thanks! I'm looking forward to receiving the 511's to see if the wider horn dispersion helps with my "not in the sweet spot" delimna. Jack

A while back someone posted a link to some adapter plates to mate 511b and K55 drivers. I've searched and searched, thought I bookmarked it and can't find it. I picked up a pair of 511b's and now need the adapters. Could someone kindly point me to the source? Thanks! Jack

Coytee, I have considered Jubs, and no I have never heard them ( i am almost afraid to, I think I would lose control of my spending). I like the sound of the Khorn. The looks are of no importance to me or the wife, spending more money on more speakers is where the wife would step in. The Khorn in the room as is sounds amazing, but I find myself getting out of the chair, walking forward about 8-9ft and standing there listening to music. I have had my eye out for a pair of 511b's, it would seem that they have a much wider dispersion than the mid horn and what seems to not be a real pricey experiment. I need to unbolt the top hats and temporarily toe them out to see if it will really make that much difference... speculation is just that, speculation Jack
