“If you look closely at the photo, you can see that the illuminated power meter on the front panel is transparent, allowing you to see the glowing tubes behind it.” Cool!

Just started dreaming about GS150 so now I need to rewire my brain and focus on those :cool: - uber cool looking - Livio did a fantastic job once again:congrats:
 
Curious, 150 watts per channel with 4 KT 150, when CJ in the new ART 150 only uses 2.
I thought that AR when designing an amplifier from the beginning based on KT 150, would "tighten" them more than in REF 150SE.

Are you sure? I think the ART 150 uses 4. You can’t really tighten anything since each KT150 tube is rated at a maximum output of 70 watts, which if run that hard, would dramatically decrease life span and cause other problems (noise, etc).

Looks good. Carries forward a bit of the GS design. I’m sure it will sound amazing - in the tradition of ARC amps.
 
The pic above is prototype and no where near the finished product.

Gotcha. But it still seems they are continuing with the same design of the GS, REF 6, etc. which I think is a really cool modern look.

Agreed. The REF3 Phono in the store is just gorgeous and a SHOCKER in sound. What an amazing Phonostage. Richard Mak was spot on with his review.

The CJ ART 150 is a stereo model. It has 4 tubes (2 per channel) and gives 150 watts.
The ART 300 is a mono model and with 4 tubes per monoblock (like the AR 160) it delivers 300 watts.

[QUOTE = Mike; 227323] ¿Estás seguro? Creo que el ART 150 usa 4. Realmente no se puede apretar nada ya que cada tubo KT150 tiene una potencia máxima de 70 vatios, que si se ejecuta con tanta fuerza, disminuiría drásticamente la vida útil y causaría otros problemas (ruido, etc.).

Exactly. Two per channel, 4 in total. They are pushing the tubes a little harder than ARC for example. 150 to 300 is only 3db difference.

The VAC Signature 200iQ amps are rated at 100 watts per channel (stereo) and 200 for monos.

Does anyone know what this means for the current REF 250 SE mono blocks? Is ARC planning on discontinuing the 250 SE's? Thank you.
 
I do not like the massive gaping hole in the fascia....I can only hope ARC will create the option to buy the amp with a stock standard fascia.

A case of swings and roundabouts, the valve and bias circuit tolerances are more important to match as close as possible with the ARC design, however the CJ is running the KT's a fair bit harder than the former, which design topology produces the least measurable distortion ?

V12 engine Or V6 if you like.

At some point in the near future or so no doubt, Ref 300 mono blocks with a freshened up facia design anyone ???
