Stel1963

one year old thread, but i go anyway Strange comments i would say. Audiolab (not the 6000, but the 8000) is a very satisfactory amp on the Fortè. Also the Jadis Orchestra, deep and fast bass, great mid and highs, and on the opposite @jcn3 had a lack of bass. Audio Innovations 500 also sounds quite good, on all the Heritage line (had them all, most of them toghether, so i could compare) although i find it a little too exuberant on low frequency, unless tubes are philips blackburn or old Mullard. Tung sol modern tubes are definitely harsh and boooming, JJ el34 are better, chinese mid to economic EL34 are thin and without bass. Exposure amps are fantastic on Fortè, but you need to get them 70-80 cm from the wall since it is a little bass exuberant. I mainly use SET on Klipsch, (La Scala, Chorus wich is a big Fortè, etc) but Fortè are not vintage La SCALA, they need at least an 805 or 835, or at least a 211. 300b and 2a3 is not powerful enough on Fortè, is great on La Scala although. If you like Sand, then those speakers are exigent. They have been created with tubes in mind, so most SS have quite some problems. Greatest, toghether with the ones above mentioned, are for me Jeff Rowland Model One, and Mark Levinson ML2 monoblocks or 27 (great great amps) Not great for me all the old sansui or pioneer of the SS era. But good (good on Fortè, great on La Scala) instead old tube ones, like SA-400 or SA-83. But they must be totally recapped to use them. Not just some cps.... practiclly most of them plus a lot of resistors.

@BEC Thanks Bob for the help on the ti diaphragms of my kg4. Finally i took off the cotton and i got back your TI diagphrams on the modified kg4. It seems the titanium was not damaged yet. It took about 100 hours to settle down, with the sound passing slowly from a little harsh to very smooth, transparent and clear. The definition and the air around instruments is awesome. They became my reference speakers and now they are in the main system. They are sounding so well i bought them a pair of SET made by an artisan in Italy with 2a3 tubes and Tamura transformers. Now their sound is simply fantastic. Best set up i had in 45 years! Well, 300$ speakers driven by 40.000$ tube equipment and i dont regret any speaker i ever had. KG4 are incredible, and so much undervalued and misunderstood! A real surprise. I was so excited I bought a La Scala from 1973. Well, they will need work. Even recapped they don’t sound not even close to the kg4. I will need your advice again this summer to make them sing.

@BEC So no cotton at all. I hope i did not damage the tweeters. I put the diaphrams on last month when finally they arrived then i got them off since they where too harsh and bright on my modified and recapped kg4. Then i put them back yesterday, adding the cotton there was inside the old phenolic membranes. They played beautifully all day. I just stopped them now. I will open the mid-tweeters again and take cotton off. How do i see if they are damaged?
