[QUOTE="thylantyr, post: 2269126, member: 560358"] [B]It's a different gain structure... Simple... You DON'T NEED HIGH VOLTAGE PRE-OUTS!!! [/B] Correct, you don't [B]need[/B] unless you have a problem that needs solving. I can argue both sides of this argument. The way I look at this is. If I was given the choice to choose 1V unbalanced preouts vs. 8V balanced preouts and the other variables remain the same including cost, then take the higher voltage balanced design because you have insurance. You have to analyze all the gear in the chain to make sure it supports it. I use proamps in the home so it makes more sense to choose XLR balanced high voltage preout preamps. Using low voltage and unbalanced is not optimal. Like I said, I don't know what the OP has for his system, but I would look into high voltage balanced preouts if his gear can support it. [B]What is so hard to understand about Low-Drive = Efficiency = Clarity!!![/B] Makes no sense, explain. [B] Less voltage = less distortion [/B] That is a design issue. You can make a 300v preout with low distortion. Many quality opamps can do high voltage preouts as a standard feature with inaudible distortion. It's the design engineers who dummy down the circuit so it only offers 1V to maintain that ancient home audio standard. lol ... ie, IIRC, the ancient 5532 opamp can do 9v rms output, a $1 opamp. If I was building a custom preamp and amplifier, there is no reason I'm dumb down that opamp to 1v, I'd take full advantage of it's abilities. [B]less voltage = less crosstalk[/B] This is a design issue. Crosstalk is determined by many variables. You can design a low crosstalk circuit with high voltage. [B]smaller components = faster components, faster components = more accurate ones. [/B] I don't understand what you are saying here, explain. [B]Pro-audio uses XLR and Higher Voltages for a simple reason distance.[/B] There are too more variables as to why do they this. There is more to gain with balanced, high voltage preouts than low voltage unbalanced. It's basic electronics. This doesn't imply that unbalanced, low voltage [B]will[/B] have problems, but there is less change of gremlins manifesting with the other.
