Wadia S7i direct to amp

The volume control in the Wadia is decent. But, it is no match for a great preamp. A preamp can provide a more natural presentation with dynamics, texture, layering, and body. This is not about lack of transparency or color. In comparison, the digital volume control can sound constrained, 2-dimensional, and less involving. If you enjoy the perception of increased detail with the Wadia direct, then that is fine. I personally don't think some of that direct detail sounds real (i.e. black background, sharp note transients, shortened decay), so in a way, that can also be considered a coloration.

@paperw8 have you tried what you are explaining?
It's just, the statement by krellfan might not be wholly unexptected, if the pre substitutes something otherwise missing.

if your question is: have i driven a wadia directly into a power amplifier? the answer is yes.

if your question is: have i driven a wadia s7i directly into a power amplifier? the answer is no, because i have a wadia 381 [i will leave it to the reader to determine how much difference that should make].

if your question is: have i modified the output voltage delivered by the wadia by flipping internal DIP switches? the answer is no because when i drive the wadia directly into the power amplifier i almost never set the output level of the wadia at 100%. generally i set the output level in the 65% to 85% range depending on the recording level of the source material.

to be more specific, i drive the balanced outputs directly into the power amplifier and i drive the single-ended inputs to a preamplifier. i primarily tend to drive the wadia through a preamplifier when i want to listen late at night. i live in a residential area, so i can't blast music late at night. when i use a preamplifier i set the output level of the wadia at 100% and vary the output volume at the preamplifier. the reason why i do this is because the sound tends to become thin when you turn the digital output level at the wadia too low (as i described earlier).

but as i stated, ultimately all of this stuff is a matter of preference. if it sounds better to you when you drive the wadia into a preamplifier, then you should drive the preamplifier from the output of the wadia. but what i am telling you is that when you do that, you aren't getting greater "transparancy"; instead, what you are getting is the sound produced by the wadia after it has been colored by the electronics in the preamplifier: that is the "something otherwise missing" to which you are referring.

I own a Wadia S7i, and I have ekspermitteret with preamps with my S7i.

The conclusion was very clear. There is a HUGE difference between preamps, and there is also no doubt about, that a good preamp does it _much_ better than the digital preamp built into the Wadia S7i. For those who may doubt my conclusion, try using a Classé Omega MK III, Tidel Preos or Viola Cadenza.

The cost for a good preamp is definitely worth the price, compared to the improvement of the sound.

i don't question that the wadia s7i sounds better to you when going through a preamplifier. but to make this point clear, you *always* go through the digital preamplifier with a wadia; there is no digital preamp bypass. in your case, the output of the wadia digital preamplifer drives the input of your preamplifier; and then your preamplifier drives your power amplifier.

..thanks for your clarification! Good to know there is background behind a statement ;-)
I cannot judge 381 vs s7i, they will have similar problems.
Interesting point about the Digital pre - but:
isn't it always the case with a DAC giving out the full power (i.e. 100%),
or you mean to say, they could make a purist version without attenuation sounding - pure?
My technical background is too small to judge this..
