Major help needed in Input and output impeadance..

I could be wrong.But I'm more concerned with the actual gain and output voltage of the preamp. The lower output impedance seems normal to me. Your preamp should do just fine. I always equated the preamp's output impedance with how well it could handle the impedance of the interconnects or load of the amplifier's input.The lower the output impedance, the less the length of the interconnect becomes factor in how it performs. I would think too much gain or output voltage could be more of a problem.You either have a hair trigger volume or one that has to be turned up more than half way before you reach a comfortable volume.

If my amplifier is of high gain say 25 or 30dB and it only takes 1 volt to reach full power. I wouldn't want a preamp with 30dB gain that claims 15 volts output. This would be like using a Megaphone while talking on a microphone..I think you get my drift ;-).Like I said I could be wrong but this is what I look at.Someone more technically inclined than myself can put it in engineering terms.

Hmm well the amp has no spec. on the input gain shown, but the pre amp is from 2 volt to 10 volt output, so if I have a 2 volt cd player I would guess I get 2 volt out of the pre, maximum out would be 10 volt, so in my case I do have a 4 volt out CD player so I assume it will pass 4 volt down to the amp... Now I would guess the only way to drive the pre to its full 10 volt out would be something like a cd player with 4 volt into an equalizer or something that boosts the signal another 6 volts and then you would be at max, so I am not worried about the preamp being overdriven really cause no source I own or even seen sold would put out that kinda voltage in general maybe some phono stage?, but it does not have the gain spec. shown on the preamps papers either, but I would guess it is 20 db gain stage.

It does have the signal noise ratio of 112db which is pretty good from what I understand, but I dont know this spec. tells us anything, also it is capable freq. range of 10hz to 200,000 hz, so its a high end piece, not the standard 20hz to 20,000 hz most are specked at, again this all may mean nothing?

Not necessarily so Matrix.The standard output voltage of most cd players is 2 volts. The standard input voltage is 1.5 to 2 volts on most amplifiers. I've seen amplifiers that need 4 volts to get full power from the unit(the designer claimed quieter operation this way). You should be able to get 10 volts from the preamp using a 2 volt source without problems.The preamp may start at just a 10th of a volt and go up from there on the volume control.You really should be fine with the preamp. As far as the crazy specs go.IMHO the 200 khz is pretty meaningless. Most of us male humans can't hear past maybe 18khz ..I dont know though some audiophiles do claim to hear like bats ..LOL.

The variation of dbs from point to point would also have more meaning for me.For example frequency response from 10Hz to 20khz +/- 3db or better is very good.Some may claim +/- 1 dB variations..it doesn't get much better than this. Most highend speakers don't achieve such a flat response anyway. The only commercial speakers I've seen claim close to this are the Green Mountain Audio speakers(after hearing them I believe it to). Even then once you get in the lower bass region the variations still drop to +/- 3dB..which ain't bad at all. There should be a certain amount of rolloff to get the correct decay and timbre of certain instruments IMHO.

Gmood1, Thanks I do understand the standard is 2 volt, but I can assure that my Wadia CD player in fact puts out the pro audio standard voltage of 4 volt at the RCA's As well as XLR, as why it much more full and powerful sounding than most players. As for speaker frequency, Mine Go 16hz to 25,000hz, no problem there either, whether it can be proven we hear or feel it is another story, but I guess the frequency's exist thats why they have products built beyond the call of duty. Not sure why but all the top manufactures flagship Preamps are in the 10hz or even 5hz up to 100 khz, or 200 khz, is it necessary? , probably not but I guess these are the flagship specs. cause yes the run of the mill and even fairly high end pieces only claim 20 hz to 20 khz... Who knows, but thanks I will see what this preamp does I was just concerned of the impeadance match, but it should be okay.

Hi Matrix,
I have no doubt the Wadia puts out up to 4 volts I was more or less talking about why 2 volts is more than sufficient in real world applications.Sorry you may have misunderstood me.As far as those flagship specs go.Look a little deeper and you'll see equipment that's not held as flagships (because of price)that have these qualities.IMHO it's more to do with well engineered gear than it having a flagship stamp.Not sure if the Wadia has this feature. But if you want fuller sound and dynamics have a modifier to put inline output transformers(bypassing the caps or op amps on the analog output of the player).That's if it uses dual differential Dacs like some Denon,Pioneer and Esoteric players.. This is what gives you the full potential of the player's dynamics and transparency.Most stock equipment regardless of cost doesn't have this.You will find it in some DIY gear though..since manufacturing cost isn't an issue.

Well enough babbling on my part... enjoy the new preamp.

Good listening
