Well arafiq,
I guess you don't trust me because I'm a professional reviewer! With all due respect, I can accept that. I have had the great pleasure of reviewing the Coda #8 & #16 amplifiers and the 07X preamplifier. I purchased the #16 and 07x to use in my big reference system.
As you you go up the Coda line each step gives you more refinement and "spit and polish" on the house sound. Doug and Eric, with this generation of gear, has produced some of the quietest, grainless, and detailed solid state gear on the market, regardless of price. However, these details are presented in an effortless, musical fashion and does not become analytical or in your face.They still retained the overall dynamics and bottom-end control that Coda always had because of their massive over built power supplies and current loading abilities.
By the way the CSib does not have the 07x preamp as it's linestage. It uses the smaller "baby brother" preamp as its control section. This preamp is still terrific, I have heard it, and gives you about 80% of the performance of the reference and much more expensive $6,500 07x preamplifier. The amplifier is the equal of the #8 single chassis piece.
All of these Coda pieces are beautifully built and our great performers at their price points, in my opinion they actually compete with much more expensive gear, but as you go up in the line there are differences that you can hear.
By the way, something wacky has taken place regarding me posting as Teajay, as I have for over 15 years. Therefore, I started this thread and post under the name Amorstereo, but it's me, Terry London, and I now review for StereoTimes website as most of you Gon members know because I always enjoyed sharing information on great products at reasonable costs.
