Kt150’s and My 200iq

The top of cage almost lays on the tops of the tubes. If it’s not touching it’s almost touching. I’m afraid even it it is not touching the ventilation and heat dissipation may be compromised so I just leave off. My wife and I are empty nesters so no worries here.
I have grown very fond of these KT150s and their sonic signature.
 
It sux to be retired! Have to wake up at daybreak then that grueling 30 minute drive to Suncoast Audio !

Hey Mike,

Lampi/Kron just released the special edition RK version of the Kron 242 tube and its a significant step up from the basic 242 that many think is the Champ in Lampi Dacs. My friend will lend me a pair tomorrow. He also gets the RK KT150 next week for his AR amps! By the end of the year, there should be a RK PX25 as well.

Will let you know, but feedback is that its a winner, just like the RK 5u4g recti!

Bonzo75 just heard the Pacific in "QuadDiffusors" system and DIGITAL beat vinyl in that set up. The Pass Phonostage may be the analog weak link there.
 
Larry,

You are a lucky guy! Were you at the SunCoast Lampi event October 2017? Cant recall if I met you there...
 
Another Vac Sunrise......yep....ya guessed it.....Nora Jones ....Sunrise..playing softly in the background!
Sorry Maxb
:happy:

Looks like a blissful setup!

Can you guys comment on how break in proceeds sonically with the KT150? Im embarking on my first tube rolling adventure with them and results are currently mixed.

Thanks! Warren

Warren - you should probably expect around 30 hours to break in most tubes. It’s tough to judge ‘how’ they break in, so maybe just wait for a bit until you get to around 30 hours. Some usual comments about 150s talk about... a stronger attack than many other tubes, a more powerful low end, and often there is a punchier high end with great definition. My experience is that the kit 150 mid ranges are not as good as a some other tubes... not bad, just not as good. Of course, I’m sure there are other opinions. Almost all tubes have trade offs. The trick is finding tubes that fit your ear, Your system, and your room. I found that I really liked kt 150s but ultimately preferred other tubes for my listening. Good luck!
 
Larry - have you noticed a preferred speaker tap from the 200iQ to the S3’s? I assume either the 2-4 or 1-2

thanks

Hi Steinkreig,

What other tubes did you prefer to the KT150s and what specifically did you find the other tubes did better than the KT150s?

With what amps did you test the different tubes?

Thanks

I have the speaker taps at 2-4 per Mikes recommendation. I have not experimented any further.
The KT150’s were already burnt in so I can’t comment on them, I did just finish burning in the quad of KR Kt88’s and I noticed the biggest improvement at around 50 hours.
I have beeen swapping the stock 6sn7 Tungsols around with some RCA’s and difference is not as obvious to me. Maybe need Sylvanias???
I really like the Kt150’s better that my stock Gold Lions. It’s like BAM!....Cajun cooking... Lol
 
The KT 150 are a totally different tube with different drivers in front of them from my experience. One pairing that I liked very much was nos Mullard in front of the KT 150 Tung-Sol, I actually thought it just slightly contributed midrange to that neutral attack of the Tung-Sols' but never was a detriment of that fast attack & slam of the 150. Another thing I noticed was with the 150, if you paired it with a lesser enabled driver, you would be struggling with everyone's opinion that the 150 is the schitz, but, I honestly think, you put the right driver out front.... well... In my experiences of slam & delivery of impact, fast & resolving.... the KT 150 deserves a mention

Finally another option of KT150...Limited Edition of KR KT150RK...also KR KT150 is available but with different physical dimensions vs TungSol...
