Sony TA-E1000ESD Preamplifier low output question?

Hi guys,

I have a Sony TA-N77ES amplifier and the Sony TA-E1000ESD Preamplifier. The other day out of curiosity i changed up the preamp and replaced it with my YAMAHA C-40 Preamplifier. WOW what a difference! everything was 25-30% louder,I did not have to open the volume as much.

My question is, why is my Sony ta-e1000esd not as loud as the Yamaha. Do i have this thing hooked up wrong? is there a problem? settings wrong? - I'm running it 2 channel so i have the RCA leads from the front 1 line out on the Sony preamp to the Sony TA-N77ES amp in (variable). Anyone have experience with this preamp or the Sony ES line?

any ideas why?
thanks

Both preamps appear to out 1.5v maximum, perhaps the volume controls have different tapers, or the Sony is configured to respond differently.
 
The Sony TA-E1000ESD puts out 1.5 volts from it's preouts. Could be the damping factors are different or the voltage gain or db signal to noise ratio. Also because its a 5.1 AV preamp, perhaps the video boards interfere with the output. I don't know but there is definitely a huge difference in output levels between the two Pramps. I wonder if there is some kind of gain controller or booster one can use in the chain to boost the mV's up. There is a input level adjuster switch on the front but when i open it up the OVER indicator starts to flicker indicating clipping...

Just read somewhere today that the The Sony TA-E1000ESD is way more sophisticated, some may say to complicated. Also, it converts all analog signals in to digital, then back out to analog post processing, I don't know if this has something to do with the sound output levels at all. It depends on ADC and DAC conversions - and these are ancient chips compared to the best current practice.
Plus, if you have hi res music, like good vinyl, SACD, DVD-A, or HDCD, they will all get mashed into 44.1/16 PCM and them reconverted back to analog, Where as the simple Yamaha C-40 preamp is all direct analog in and out.

thoughts?

It's simply a difference of gain structure that the outputs are different at similar volume positions.

Want the sound from the Sony to be louder? Turn the knob more. Doesn't mean one is better or worse or that something is wrong or that something will be damaged. They're just different.
 
Oh, and perhaps the biggest point of all?

Doesn't mean the amp has suddenly become more powerful because it gets louder, sooner in the volume rotation with the Yamaha. Again, it's just a difference of gain structure.

As far as the Sony digitizing even the analog inputs, yeah, that appears to be true. So, if that's troublesome then maybe a reason you choose not to use it. However, in and of itself, that it's digitizing is not the reason the output is less at similar volume position.

respectfully, I don't know if I agree. Both volume knobs have a start (0) - middle (50) end point (100) and if on one the mid point emits lets say 100 db of sound and on the other mid point emits 75 db, to me it would mean that one has more amplification or something...Now maybe I'm wrong...I'm no physics professor or engineer or anything...I'm just a humble lover of hifi., but I am open to understanding as I am here on this forum to learn...

There is nothing to disagree with. As I said before it's just a difference of gain. Nothing more.

Gain vs. power is commonly misunderstood.

_este hilo es de 2016 , solo voy a dar mi opinión
_te puedo decir que el Sony TA-E77ESD entre el punto de inicio (0) hasta el punto (2,5 al 3) suena casi a la par que otro amplificador Sony de 100w+100w que tengo también pero en tanto llegas al punto ( 3) en adelante se vuelve otro amplificador diferente dando nota de su potencial
_en un principio la sensación era como que faltaba potencia pero en realidad te acostumbras y creo entender que puede ser alguna configuración de Sony , también te puedo decir que desde el punto (0) al punto (2) la entrega de potencia es más elástica y puedes apreciar el ajuste del volumen en esos niveles tan bajos , es decir que Sony en un punto de volumen del (2) se ajusta mejor el volumen y es más preciso en la noche cuando quieres escuchar música a un volumen bajo pero con presencia sin molestar a tus vecinos y sin tener que estar jugando con el volumen buscando el punto , al conectar tu otro "pre" puede que en un punto estar muy bajo el volumen y con solo mover el volumen un poco estar muy alto ..

respetuosamente no se si estoy de acuerdo. Ambos controles de volumen tienen un punto de inicio (0) - medio (50) - final (100) y si en uno el punto medio emite digamos 100 db de sonido y en el otro el punto medio emite 75 db, para mi significaría que uno tiene más amplificación o algo... Ahora bien, tal vez me equivoque... no soy profesor de física ni ingeniero ni nada... solo soy un humilde amante de la alta fidelidad, pero estoy abierto a entender ya que estoy aquí en este foro para aprender...

- publicó otra respuesta con mi opinión,
_ en este solo voy a exponer según ha publicado donde puede estar el error o falta de potencia
_dices que el pre Sony está conectado en la entrada variable al n77 , en este punto esa entrada se controla la potencia de salida por sus potenciómetros es decir que de estar estos colocados al 75% del total el amplificador solo te ofrecerá el 75% de su potencial por mucho volumen que des al preamplificador,
_si por algún casual que se pueda dar conectaste tu preamplificador al RCA que está al lado de la variable donde dice "fijo "el volumen al que esté puesto el preamplificador no tendrá ninguna limitación o restricción por los potenciómetros de la conexión variable,
_entonces puedes tener 3 situaciones
1⁰ el Sony está conectado al ta-n77es por RCA variable
2⁰ el Yamaha está conectado al ta-n77es por RCA fijo
3⁰ puedo estar muy equivocado pues al decir que el punto del volumen ya sea (0), (2), (5) siempre suena inferior al Yamaha este puede ser el error, tal como te he comentado el mío pasando del punto 2 al 3 y en adelante la potencia se siente , también puedes tener un condensador electrolítico que este fallando y al estar fuera de valores altere el funcionamiento
 
mil Sony ta -e1000esd , tiene un botoncito para la ganancia de las entradas analógicas y digitales , espero tengas solucionado el problema
 
I used a 1000 for about 12 years (then replaced with a used 2000). I don't recall it having low vol output, as I ran it through a Music Reference RM-9 tube amp. When the 1000 croaked, I bought a 2000, which has source direct circuitry (or whatever Sony calls it). On the 2000, I pulled the video board out to help with cooling and any other benefit, as I used it for straight 2-channel only. Still have the 2000 in working condition, but have moved on to keeping my audio listening without A/V components. The achilles heel of both units is the rca input jacks, as they can't take much abuse or will need re-soldering.
