Without hesitation: Aries Cerat Incito tube preamplifier (approx. $10K).
- Ultra-quiet zero feedback Single Ended Triode (SET) preamp with transistor-like figures.
- Big and heavy (33Kg !). 3 chokes in the circuit. Huge power.
- Has convinced even those who came to believe in passive-preamp exclusively.
- gobsmacked all reviewers who tested it, including Christiaan Punter, excellent Dutch reviewer (hifi-advice, tested the 'S' version, with separate power supply, more expensive).
- It blew away my YBA 1 preamp (separate power supply).
- plays well beyond its price
- SOUND: lots of timbre, body, naturalness AND transparency, dynamic, speed, 3D wide image, sharply focused: the best of both world. Does NOT sound like a typical tube preamp (rosy-view, etc). Can the low-hand; no other zero-feedback SET preamp can.
- no tube rolling allowed: they used a Siemens tube of super-high trans-conductance. But you can fine-tune the bias.
It was the more impressive upgrade my system had.
It is also the most stable and reliable hifi component I have ever had.
I wish I had discover that extremely talented manufacturer sooner. Built in Cyrpus by an aeronautic engineer who worked on Dassault systems.
Here a picture of the 'Incito S' version (separate PS). An 'Incito' (basic) version also exists: embedded PS; it is the 'basic' version that I own (approx. $K10-11)
If necessary, plan a trip to discover it. It will save you years in your audiophile quest, I promise. I wish I had discovered it sooner.
