Findings
and short facts |
|
|
| |
Here
are some useful facts I discovered during the testing of
my ES components. The full list of my ES components
can be found here. |

| :: |
Bi-amping with two N55ES amps sounds much better than only one N55ES (mind you,
those JBL Ti 5000 take a lot of power to drive correctly). |
| :: |
2xN55ES in mono mode for LF and one N55 in stereo mode for HF did not give
such good results. I guess mono
mode sounds harsher than stereo. |
| :: |
There
were 3 versions of the N55ES (AEP, for German market)
- I describe my findings chronologically:
1. 7-digit
s/n - 450XXXX, silver input jacks, cylindrical
ES transformer (same as in N80ES),
2. 7-digit
s/n - 450XXXX, gold-plated input jacks, cylindrical
ES transformer (same as in N80ES),
3. 6-digit
s/n - 50XXXX, gold-plated input jacks, square transformer.

2xN80ES in stereo (bi-amp) mode provides the same results as a single N80.
One N80 sounds much better than two N55 in mono-mode. |
| :: |
TA-E1000ESD preamp, despite having two digital processors, sounds very natural
and is a bit noisier than the TA-E80ES using balanced
connections. |
| :: |
TA-E80ES has better power distribution - it seems that the frequency response
compared with TA-E1000ESD is very good at low volume. |
| :: |
TA-E80ES uses a different IR remote control code for volume control than do other
Sony amplifiers. |
| :: |
SDP-EP9ES uses a different IR remote control code for volume control than do
other Sony amplifiers. |
