ART 150/300 Anniversary Amplifiers

Post by Matsaly » Thu Apr 13, 2017 3:53 pm

The creative talent at cj are introducing several new products. I thought this might be of interest to members on this forum.

I have no affiliation with cj. Contact them directly if you have questions.

Very cool. I like the see-through tube cage.

Well that's more like it! Had a feeling the CJ crew were going to offer something of this sort, especially with KT150's.

Now, for those who purchased the ART amplifiers, here's something that comes along and would probably outclass the ART's, and the vicious cycle begins... hooray!

I've heard a few amps with KT150's, ARC Ref 150SE, the new GS series and Ayon integrated. These were driving the Martin Logan Ethos and Summit 'X' speakers, plus listened to the ARC GS series with Sonus Faber Strads and Elipsa's. Although, relatively comparable to solid state bass, the rest was far over-blown. The extended airy highs and smooth open midrange of CJ's designs was as if on steroids on a muscle bound adrenaline adventure...
This is why I love the CJ sound so much, all of that over-blown dynamics is shaped into musicality and allows you to really enjoy your music, rather than be shaken around and thrown all about the room.

To me, the sound was just way off, not really controlled, over bloom in critical frequencies of the midband, only positive aspect was the bass was pretty solid when driving the Sonus Fabers, and although the Martin Logan's were active bass, the KT150's made the midrange sound really "fat." It was not accurate, nor linear not even articulate mid-bass. When switched back to a KT120 and the 6550C, and of course the EL34- aah! now that's what I call music.

I may be presumptive here, without listening to these new KT150 designs and especially from CJ, perhaps they are controlled and well presented, I wouldn't know.

It's great to see that CJ is offering these lovely looking amps and anniversary editions. Price tag, seems to be competing with the best out there. Several anniversary editions come to mind from McIntosh, ARC, VTL, special edition versions all have something special to offer.
US retail is only half that story, Aus prices would be in the heavenly range of 28-30 grand upwards!

I am sure the LP125 series, in form of monoblocks and stereo versions (LP125sa) would be equally good, if not in subtle differences.
One of my fellow mates who was getting the new Martin Logan Ren15, also happens to have a MG20.7 now and is actually getting the new Classic 120 fitted with EL34's. I'm just waiting for an invite when this gear arrives, since the Melbourne dealer is no where near to the new classic amplifiers, still trying to get rid of old stock...

It's definitely a good thing these amps arrive in due time because they could offer a challenge to the well known ones already in the market. Similar high-end sales of around 30 plus grand on amps take place across the road... so to speak. CJ awareness is not getting the right recognition. Other brands such as VTL, ARC, Pass Labs, Jeff Rowland, Accuphase, Luxman, Divialet, and Ayon are getting out there in the limelight. I personally feel CJ sounds way better than any of these put together.

Therefore, this is great timing I think, to introduce these new editions and start people thinking about some serious audio. Whether these new amps such as the new Classic, ART's, anniversary editions etc, would ever make a mark here, I wouldn't know. It would take someone who is very passionate about CJ, to chase the shop owner in order to close a deal... I wonder what text book rule that came out of?
Sounds like Richard Branson saying "the customer is not always right."

By the way, if you do happen to audition these new beauties, do let us know. In the meantime, I will keep a close eye on those new Classic amps supposed to arrive soon, must audition the Classic 120 (EL34) and try to bring one home for a weekend session. Listening in demo rooms at the dealers is very different and has far too many variants, not found in the typical living room.

Until then, thanks for sharing this info, and cheers to CJ's 40th!

It is interesting to see C-J use the new KT-150 tubes. I only saw a couple of amps at AXPONA use these, but there were many using the KT-120. I would trust C-J to get this "right" and voice the new tubes to sound like their other amplifiers.

A 300 watt monoblock. Hmmm...what I could do with that power! ;) Is this the highest-powered monoblock they have ever produced? The largest I can think of, off the top of my head, are the Premier 8s which unleash 275 watts each.

Yea, only 100 hours or so... although they run them in at CJ for 40 or so hours so all in all they have upwards of 150.

They are not quite as pretty as the ART Monos to look at, but they surely are an improvement sound-wise. I really enjoyed the ART Monos but these things fill in the low end like a solid state amp. it was immediately apparent. :D

And 8 KT150s definitely radiate as much heat as 16 KT120s. I'd somehow become delusional in thinking these would run a bit cooler than the Monos.
No way.. but that's OK as I'm a tube guy for better or worse.

Hey mate, now that's one outstanding pre-power combination you would ever need!

Good one, good one. and I should know the at least the type of sound you're getting with those maggies. In our last reference system, when the dealership was going strong, one system that was probably the best in the entire little island of Colombo, was the CJ premier 8 mono's driving the MG20's with a Prem 16LS. Later on we sold odd the 16LS and got an Act2, sonics were improved even further, and then I left and closed all shop!

That was a superb sound indeed, and one that was very easily compatible even with the mighty Infinity's RSB1's and the Apogee Diva system. I will be travelling early next year to ThaiLand via Spore, and plan to audition the new ART150 & 300's. Just to experience the new sota from CJ. Really no point in planning on acquiring these amps in Aus, we're talking drug money pricing over here...

Enjoy mate and do let us know how the sound improves along the way. Most of the amps with KT150's to me were not upto the mark. I listened to the new ARC, plus Ayon integrated, didn't quite have that supreme control factor of KT120's. It was an over-blown sound, and not musical at all whatsoever, although very dynamic, that was about it.

With CJ incorporating these new KT150 tubes, that must be one top notch design, afterall CJ knows and has been building tube amps for decades.
Great stuff indeed, must have a listen sometime soon.
Take it easy and have a glorious one with those maggies and cj mono's- that will be one true top end system, regardless of price, and can easily beat the most dynamic drivers out there. Excellent one mate, well done!
Cheers, RJ

I'd heard all kinds of reports on KT-150s in general. Like most things in this crazy hobby, the KT150 was either the greatest valve every made or pure crap.. and everything in between depending on who you asked.

In speaking with Jeff at CJ prior, I'd made it clear to him that I liked the ART Monos and would happily live with them forever.. So in essence I was saying that I'd hoped CJ didn't completely change the character of the 300s compared to the Monos.
Jeff had always been very straight with me in the past, so I took a chance on buying the 300s.
Bottom line.. they do in fact meet or beat the ART Monos in every conceivable way. The low end is supurb and going up from there is as good or better than the monos in every respect.

I think part of the problem with KT150s is that they are a newer tube, and many manufacturers do not yet have a grasp on what to do with them. C-J was able to harness that tube's unique properties in these newest ART amplifiers to great effect, but others might not. It has also been said that power tubes do not make as much of a difference as the small-signal tubes. Plus, there is always that fear of change by some audio listeners. ;) At AXPONA this year, I saw maybe one or two other amps using the KT150s, but can't remember which manufacturers these were. I think once a few more good products are out there using this tube, it will gain more acceptance. It certainly isn't crap!
