Automobile industry now improved a lot regarding the digital and sound or audio technology. Car connection is one of the latest find of this category. Car infotainment and entertainment are the two most important aspect in case of a car manufacturing company. Because, these days, cars are need to be digitally enabled to help the operator whenever necessary. The communication will be a lot easier. Car sound system needs to be more clear and advance. Car repair and service is more useful whenever any machinary or engine problems or even any sort of technical problems occurs.

I was looking for a phono preamp to run with my PrimaLuna Dialogue Premium HP Integrated and this little beauty popped up. The review I read spoke of 'rock' music and AC/DC and that is what caught my attention. I loved the sound of my tubes but I also wanted a preamp that would keep my rock and power pop clean and tight before sending the signal to the tubes - this appeared to be the phono stage. I then introduced myself to the manufacturer Peter, and had a few conversations via email. I knew that I could try it out and if I didn't like it I could then just simply ship it back for a refund. I still have it in my system today and really dig it. One solid unit that I am very musically happy with.

I liked the report, although this preamp cannot be heard carefully because the Liberty direct selling system.
Query: Is B2B-1 vastly superior to Graham Slee Accession M, or the Reflex M.
It is a high bet, buying it without being able to compare it. Except for, "It's a mini Boulder 1008, I found myself thinking-a big compliment."
I would also appreciate if dual mono operation is convenient, for Soundsmith H-output the Voice / the Aida.
Thanks!
