Yes, correct, Art re-wired the output, to use the 4 ohm taps from the output transformer.

So it means that he gets 25 W on 4 ohms speakers ?
If I do so on the CCQ, will I get 70 W on 4 ohms or 35 W ?

Depends on the amp. With many SS designs, you get twice the power at the lower impedance, so a 100 Wpc SS amp at 8 ohms will deliver 200 Wpc at 4 ohms.

But that doesn't always hold true with tube amps...my C-J gives 70 Wpc at either 8 ohm or 4 ohm loads....might have something to do with the differences in transformer design between tube and SS amps.

Serge,

$$$ arre but numbers to you, akin to the number of 4 exotic wheels you had lined up in your garage.

Just tell yourself to find that one 4 wheel that you no longer fancy, and presto, it should be good enough to exchange for the ultimate pair of Latour (just go for the biggest one).

Affordability is never a word in your dictionary. Its about "WHEN".

I am glad you are making the first move to go listen. I'll stay awake to read your post about it and more so, when you decided they shall be in your possession.

Cheers!

I was told that the power of Shindo amps is divided by 2 from 8 ohms to 4 ohms.

I do not know. This isn't always necessarily true that it is 'exactly' halved.

Matt,
The technical informations about Shindo products are pretty rare to say the least.

The design goal around the CCQ's is 70wpc into 8ohm and above. This is how he rates the amps. He is not designing them for use into speakers that ideally require solid state power, so rating them into 4ohm is not in his mindset, you have to understand. 86,87.. 88, 89db w/8Ω~ stable impedance and above, not a problem..

Sincerely,
Matt

Ok Matt,
This is very clear. Thanks a lot. I will forget Shindo's amps for my speakers. You won !
In an other thread, you were stating that "high power " ( if 70W can be called this way...) Shindo amps can drive almost any speaker on the market. I believed I missed the point about 8 ohms and above....
