Thé sharp optinica sm3000 is a amp but with a pre-out output ans was used as a preamp on thé SAE 2200 amp

it is an old SAE .. have tried it at the seller's home with preamp (pre-out) of an old sharp optonica sm3000 and klipsch RF7 mkIII. Sounded very fine. but will it be the same in my home ? that's the question

i can buy a SAE 2200 amp ... do you think it could be fine for my CW IV or my La Scala clones ? another seller has a McIntosh MC2120 , a little more expensive. Which from these two amps would you put on the Klipsch speakers ? or none of both ?

The room is perhaps the most important ... i was this afternoon near me to a guy for listening a SAE 2200 amp. It was drived by an old optonica preamp. The speakers were Klipsch RF7 MKIII, lthe cd player a T+A. This set was very nice to listen. I think the RF7 mkIII is not at the same level as the CW IV .. but it sounded really good. Bass was in the room, everything was fine to ear.

Ok, if you have only digital sources .. it's not my case.

Hello Kalifornian, You mean the xilica xd-4080 dsp? I will have a look to this dsp, if i can find one around me

Thanks you Chief bonehead I am old too.😃 I will really try to find a preamp with tone controls like the McIntosh. I have bought a dayton audio dsp-408 but he is noisy on my la Scala. Perhaps a problem with my actual preamp or bad wires.

Chief Bonehead at what model of tone control do you think? something like a dsp-408 perhaps or better ? i would like to find a McIntosh preamp like C33 ou C504 or similar, with the possibility to up some frequency range

no gasket betwen the adapter and the horn .. my horn is in wood, i think it is not necessary to put a gasket between these 2 parts. i will unscrew the driver from the adapter during this week because i have to open the rear of the upper cabinet ..

I have forgotten to say that i have put 2 Eminence es2ba adapters between my atlas sound pd-5vh drivers and my wooden built k-401 horns clones.

Oh it's really very friendly from you KT88. Thank you, thank you, I will try to do better with rubber than with the foam (the foam i used is pretty dense despite everything but perhaps not so good as rubber) Thank you to have told me the diameters and thje thickness

Yes , i will cut another pair of gaskets - i just have to know the right measures and thikness

yes, but it is not easy to have them really round

I have built my own clones of k-401 horns with wood. To put my drivers on the horns, i had to use adapters. The gaskets between horns and drivers are badly self made. Is it important to have very good gaskets, does it change the sound if the are not right done ? Pictures ... so you can see what i have done . the gaskets are white on the picture. It is a foam gasket.

Hello mustang_flht, just a small remark, it does not seem to have heard that closing some of the vents made it possible to get more bass. It allowed me to further tighten the bass and not to go down lower in these. But I will still try what you specified

Yes mustang-flht, and i did it on my onken .. i have not tried on my cornwall IV .. i will try it soon.

Perhaps, this summer, i come near Beaucaire ( my girl friend has family in Aix en Pce )

I shipped Elipson spheres in staff (plastre and filass), for whom to know these speakers, from the meeting to metropolitan France without any breakage. You should actually know packing but it is feasible. I sent 3 pairs of spheres, those of Elipson 4240, the smallest with broadband Supravox and others still with HP brand that I forgot the name. It takes double packaging, then plastic bubbles, double cardboard, and that none of the walls of the cardboard affects the article shipped.

Beaucaire, is in the south of France ? with a beautiful castle or not ?

In any case, if you separate, and depending on the selling price, do not hesitate to contact me again. After me, I have a shipping cost and taxes to add to the selling price, so if, in addition the repairs are expensive, it may not be wise for me. I missed a C504 on Leboncoin (well-known sales site in France), Arrggg. It was in very good condition for a price of 750 €. I would like to find a C504 couple or better a C33 and an amp with autoformers type 2125 or more powerful for my CW IV.

For the repair of MC2125, I hope the repairer will use components identical to those in place and not equivalents.

Sorry for you. You were si happy to try this Lab Gruppen

Normally, the fans should go on only if the amp begins to be hot. I had a long time ago a sono amp with fans. They never started when i was listening music on hi-fi speakers at home

I am surprised that the fans are so noisy. Does it mean that they are running even with a cold amp.

Hello mustang_flht Perhaps you can change the fans ans take some with low noise. For your mc2125, it is perhaps a false contact. I would like to have a mc2125 with a c33 or c504 preamp
