Reasons for selection SUNSUI AU-D 707X Dicade<\/h2>\n

\"Sansui<\/p>\n

I had never checked the sound of the actual unit, and based on a few word-of-mouth reviews, I felt that this amplifier could produce something close to the sound I was looking for.<\/p>\n

I had originally used the AU-D 907F<\/strong>, also by Sansui, but thought it was a bit mature.<\/p>\n

When I purchased the AU-D707X Decade, I was using a SONT CDP-X555ESX CD player with a thick mid-bass sound quality, and I wanted to add more punch to the sound.<\/p>\n

\"Sunsui<\/p>\n

Also, I am using Sansui SP-100i<\/strong> speakers, which have a wonderful mid-bass sound, we chose an amplifier that would be compatible with the speakers.<\/p>\n

Characteristics and Sound Quality<\/h2>\n

\"\"<\/p>\n

The mids and lows sound great, as does the thick sound of the circuitry using X-balance.<\/strong><\/p>\n

Especially in love with songs featuring vocals and the sound of live instruments.<\/strong><\/p>\n

However, the speed of the sound is heavy and slow, so electronic music does not really sound well.<\/p>\n

Vocals are also not well balanced when electric guitars and programming are mixed in. So I had to set up a small sub speaker to balance it out.<\/p>\n

It still does not sound modern well. However, only certain genres have a sound that can only be experienced with this model.<\/p>\n

Is there a secret in the circuit?<\/h2>\n

I realized something when I was trying to figure out if I could successfully combine digital data and analog data playback through a thought process.<\/p>\n

I was using “ONKYO’s R-N855(S)” as a digital amplifier<\/strong> and line output from it to “AU-D707X Decade”, but I still could not make the recent digital data sound well.<\/p>\n

However, CDs sound better through the “AU-D707X Decade”, so I was wondering how to use it.<\/p>\n

My main listening is compressed Spotify data, I bought a Chinese power amplifier (FX-AUDIO- FX-98E) to do so.<\/p>\n

Although quite cumbersome, digital sound sources are connected as follows.<\/p>\n

Spotify (smartphone)” -> “ONKYO’s R-N855(S)” -> “AU-D707X Decade” -> “FX-AUDIO- FX-98E” -> Speakers<\/strong><\/div>\n

CDs and records were used in connection with<\/p>\n

CD\/Record” -> “AU-D707X Decade” -> “FX-AUDIO- FX-98E” -> Speakers<\/strong><\/div>\n

Incidentally, the “AU-D707X Decade<\/strong>” does not have an external output, so the REC terminal is used for “FX-AUDIO- FX-98E” LINE output.<\/p>\n

In this case, volume control is not possible on the Sansui amplifier side, the sound is actually increased by “FX-AUDIO- FX-98E”<\/strong> through “AU-D707X Decade”.<\/strong><\/p>\n

What I thought was great about Sansui was that the sansui tone comes on just through this amp.<\/strong><\/p>\n

It loses its sharpness, but the sound becomes softer and more flavorful.<\/p>\n

Malfunctions are bound to occur<\/h2>\n

Currently, I am not using this amplifier.<\/p>\n

The circuit became locked up after prolonged use and was not stable in any way, so I decided to remove it from the configuration.<\/p>\n

The repair can probably be done for about 20,000 yen, but for Spotify sound, I can honestly say that the sound is smaller and more separated without the SANSUI amp,<\/strong> so it is only useful as a CD\/record-only device.<\/p>\n

My sub speakers have broken over the past year and I have been hesitant to send them in for repair because of the systemic problems with this amplifier.<\/p>\n

But there are times when I really want to hear the sound of this amplifier. There is no doubt that when it get hooked, the sound is wonderful and irreplaceable.<\/p>\n

Far from it, the high-spec, low-priced Chinese amplifiers are wonderful for sounding digital sound sources.<\/p>\n

Now I have been beaten by the cost performance of Chinese amplifiers, but I will never forget the sound of that Sansui.<\/p>\n","protected":false},"excerpt":{"rendered":"
