Dartzeel w/Other Preamps.

Aye. 

I also had the dart combo. Someday I replaced the NHB 18 with the MFA baby reference preamplifier. Never looked back. Don’t waste your money. IMO darts are extremely overrated. I sold them both. 

@thanasakis can you tell me a little more about what you didn't like about the darts? What makes them so overrated?

j-wall  I bought them in 2010. In the third year the power ampl failed (one output was not audible). After multiple communications with Mr. Deletraz (very nice man), I sent the amp to Switzerland. Returned within a month. The fault had been fixed. I sold the amp and the new owner reported another malfunction (one eye not lighting up properly). I don't know what he did next. That's about the amplifier. Let's go to the preamplifier. Within a year of buying it, I found that the black rubbers surrounding the two potentiometers had started to polymerize (!!!!!) I was shocked as soon as I saw them. From that day on, I was careful when I needed to rotate a potentiometer, not to touch the rubbers, lest they be cut (!!!!!!!!). Unacceptable for a machine worth €20,000 (when I bought it). As for the audio quality, they sound great! but no better than the preamplifier -power combo I use today even though they cost less than half what the darts were! That's all.

I had the 108 pre-SCNP connected to a VTL 7.5III preamp and it sounded great. I upgraded to the 108 Model 2 and the improvement was huge. The 7.5III is a great companion to the 108

I've never owned an 18NS but would like to  do an A/B comparison with the VTL someday. A audio business owner I know sells Dartzeel, and he loves the 108 Model 2, but feels while the 18NS is a great sounding preamp, there's a lot better bang for your preamp buck out there.  He would recommend the the Aeris Cerat line of products, which he also sells.

I've had numerous email conversations with Herve' over the past few years. While @thanasakis has had issues with the Dart, I can't help but feel if Herve' is made aware of an issue, he'll do what he can to fix and improve his product.
