Var hälsade på en vän i italien som hade byt ut sin förstäkar till YBA som jag själv aldrig har användt. Nu använder Silvano samma högtalar märke som jag (Kharma) och det funkade mer än utmärkt. Han hade skaffat sig YBA Passion 1000. Har varit inne gå att skaffa mig ett rörsteg från Mastersound men efter denna provlyssningen hos Silvano så tror jag att det kommer bli YBA istället.
YBA tillverkar CD spelare,försteg och slutsteg mm
Följande modeller finns hos YBA :
Signature (Silvano hade signatures försteg)
Passion (Silvano använde denna modells största slutesteg (Mono)Passion 100)
Classic (har ingen info om denna modell kolla hemsidan)
Initial (har ingen info om denna modell kolla hemsidan
Lägg ut deras senaste prislista om någon är intresserad.
Lite info om Försteget
The three models of the YBA Signature line all have the following original aspects :
* implementation on two separate chassis of the YBA 1 preamplifier circuit in order to obtain complete separation of left and right channels
* floating ground power supplies without any current flowing in the grounds
* highly reinforced power supplies through the use of transformers of the type traditionally used in power amplifiers
* highly stabilized and filtered power supplies by means of a large number of capacitors, which permits a disconnected equipment to continue functioning for several minutes
* damping circuit modules with synthetic diamond particles of sizes selected for their effects on frequencies
* custom-constructed low noise transistors damped with a special material producing, in listening, the best signal to noise ratio yet achieved
* the potentiometers are abandoned : volume control is performed by switching of YBA resistors via special relays, selected for audio - this represents a unique innovation.
The remote control allows operation of source, phase and mute. This remote control does not interfere with the audio signal since it has a separate power supply.
It should be noted that this remote control does not eliminate the possibility of manual adjustment.
The three models are, in contrast, essentially differenciated in the size of their power supplies.
* The YBA Signature standard is equipped with two 160 VA transformers and thirty-two 4,700 µF capacitors
* The YBA Signature 4 Chassis (special power supply) is equipped, among other things, with four 160 VA transformers and sixty-four 4,700 µF capacitors
* Finally, the YBA Signature 6 Chassis preamplifier (photo above) has totally separate LINE and RIAA power supplies. This is implemented with :
four 160 VA transformers and sixty-four 4,700 µF capacitors for the LINE stage, and two 160 VA transformers and sixteen 4,700 µF capacitors for the RIAA stage
The YBA Signature 6 Chassis preamplifier attains the height of musical transparency.
It is now recognized as the reference for preamplification.

The three models of the YBA Signature line all have the following original aspects :
* the YBA 1 amplifier circuit has a unique simplicity and effectiveness ; the current state of our knowledge permits no improvement. Because the signal in this circuit does not traverse any passive components, but only transistors, Yves-Bernard ANDRE has, for the YBA Signature line, improv |

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe.
I dispute that.
I say there is more stupidity than hydrogen, and that stupidity is the basic building block of the universe.
