Has somebody seen frequence responce of this phono amp. If you have please put link here.

I have a scope that I use for alignment, and does a good job of tracking frequency.I can try to measure it tonight. What is it you need to know exactly?
And definitely get rid of that stock tube! Running a vintage 12AT7 USA made, same gain as stock. I am waiting for some real 12ax7's to come in this week. Should almost double the gain from what I've read on tubes.
Exactly I want to know what input capacitance affects to frequence responce.
Nobody seems to know the input capacitance of bellari. To my cartridge best value is 220pf. If the capacitance is lower does treble go higher or lower. If you can measure capacitance that would be great help to me.
(sorry my poor english)
If I remember my electronics right, lower capacitance would yield brighter sound and less controlled bass. Might do a new generic post asking this question, a lot of guys on here know their stuff really well.

This is just what manufacturer says. I want to see some measured specs.
the mfgrs specs normally are accurate in this area.

What mag has tested this phonoamp except Hifi+.
and largely meaningless because they are usually specified at a low wattage (in the case of an amp) or low voltage (in the case of a preamp)output.The response characteritics of any given preamp or amp are a function of the their ability to handle high output levels.
This is one of the reasons why devices with identical frequency response specifications can sound so drastically different.For instance a preamp with a smallish power supply can sound phenomemal with great bass and smooth extended highs at very low listening levels, but when pushed a bit, it can all of a sudden lose the frequency extremes and sound closed in simply as a result of inadequate power supply.
At best, performance specs are but a minor guideline and they are not a true indicator of what any unit will sound like when inserted to any given system.
....that is, unless you subscribe to the Julian Hirsch school of "thought", where all amplifiers and preamplifiers sound the same!
cheers,
Send an instant karma to me...

Brain waves to you Ray ! As I was reading your excellent lucid description of the relative meaninglessness of spec's, I was grinning as I immediately conjured up a vision of Julian Hirsh
deep in O scope readings.
Ok. But I have now Creek Obh 18 and I found it tooooo Bright. Input capacitance is ok 300pf - 220pf Shure m97 + Denon DP 51F Wire. I bougt Bellari And Didnīt find anyware input capacitance. I wonder what it is.
