Have you heard darTZeel Amplifiers


I’ve been interested in a darTZeel NHB-108 amplifier since hearing about them a few days ago. Has anyone heard a darTZeel amplifiers and what is your impression? I was intrigued because their NHB-468 has a very high slew rate of 200v/µs, which is the highest I’ve ever seen. The NHB-108 model 2 is rated at 88v/µs. I have always been impressed with amps that have a high slew rate because they sound transparent to me and reproduce transients other amps seem to miss. I have had many amplifiers including a modified Sony TA-8650 which has a high slew rate, that will go in my estate if it lives that long. I like the sound of Bryston amplifiers a lot too. I realize the price is high for darTZeel even used, but I’m looking for something because I would like more clarity in the midrange especially. I don’t want to even consider tubes unless they have an auto-bias feature. Thanks in advance.

I have heard them on several occasions and all of the positive accolades are well deserved and warranted. 
Thanks for the link to the article from Mike Lavigne, lots of good stuff from everyone! That was a good thought from jetter, hadn’t thought about that aspect considering the difficulty to replicate. HAVE had surprises from Ebay before. Guess if I’m going to invest $13k +, maybe I should buy from a reputable site like AG, but that one is $30k list. So without the latest upgrades, would you buy the Dartzeel again, elrod? Have you heard anything else that you think would come close? Bryston, 60v/µs. Kind of hoping Mike L would chime in, don’t want to bother him with a PM.
Yes I would buy the Dartzeel all over again in a heartbeat. To me the Dartzeel is the whole package. Only real amplifier history I have is with the old Yamaha VFET amps, B-1 & B-2 and I'm moving on from those.

You can contact the founder of Dartzeel, Hervé Delétraz at rehve@dartzeel.com. Give him the SN of a unit and he'll check if it's authentic.

@fiesta75, 

Buying darTZeel amp new or used is only one part of the equation. A preamp or source component with 50 ohm 'zeel' interface is another. The darTZeel components performs best using its BNC interface. 
I own many of the darTZeel products & I currently have listed a 108 with all upgrades. Of course I am bias towards their products but with that being said the they make some of the best sounding equipment in the world....
Customer support is outstanding & I love the way they do their upgrades for their line. Instead of coming out with new models every other day they offer a path to upgrading current models, I for one love this option.
I highly recommend auditioning a listen, you will not be disappointed.
Good Luck.
