New (integrated) Amp Day

Recommended Posts

Evening all...

 

Well, as some of you know, I was in the market for a new amp, and based on a few recommendations, and a lot of wavering between a couple of different units, I purchased a Yamaha A-S2100.

 

I cam home from work today, and within an hour the UPS truck pulled up to drop of my much anticipated purchase.  Initial inspection showed no apparent damage to the packaging so by all appearances, the unit had a safe journey.  After enjoying a wonderful meal prepared by my wife, it was time to unpack.

 

I cleared a space on my cabinet to temporarily accommodate the new unit, and with utility knife in hand, ever so carefully begun to cut away the packing tape, fighting back the excitement.  Pulling it from it's packing, I set the unit in it's temporary location and admired the denseness of the unit.  Almost as if chiseled from a block of aluminum, it was heavy, and very sturdy in feel.  A quick inspection for damage revealed no visible flaws, dents or scratches, and I was impressed with it's overall fit and finish.

 

As I proceeded to make the necessary connections to give this beauty a test drive, I opted to forgo connecting my equalizer and run the bass and treble flat on the unit for the initial experience, if for no other reason than to just hear its native tone.  I power up the unit, and queue up 10,000 Maniacs - In My Tribe.  It's difficult to give you a review of what I heard, as I have very little experience with a very small sampling of audio equipment, and can only compare to what I have been using for the last 10 years or so.

 

Let me say, I wasn't impressed......

I was absolutely floored.

 

The clarity from this unit was the first thing I noticed.  Very crisp and accurate.  There also seemed to be an evenness across the mid-range and highs.  The HK unit seemed as if the highs dominated and really stepped over the mids.  The bass response was good.  I live in the low-end, probably much more so than most, but it was certainly enjoyable and seemed more detailed, and not so muddy.  If I had to make a complaint, the only one so far is that when adjusting the treble or bass, the unit clicks and briefly stops playing.  It's almost as if when in the flat position, it is "off".  When you turn to adjust the level, it turns "on", clicks and stops playing for a second.  Is this normal to Yamaha units?

 

I hope to find some time this weekend to check out the phono amp, as well as open the unit up a bit and keep the neighbors pissed.

 

I want to send a special thanks to those that responded in my other thread that helped me to make this purchase.  In my ears, it was the right one.

Congrats on the new toys.  What beauties.

You had me concerned for a split second. :o  :D

My A-S1000 does the same thing.  In other words, yes it is normal for these Yamaha integrateds.  The clicking(and muting) only occurs when first engaging of either bass or treble.  Of the many integrated amps(8) and stereo receivers(5) I have owned, the Yamaha A-S1000 has the most "natural" sounding tone controls I have ever used.  No obnoxious artificial coloring of the signal is detected.

 

This may explain the technology some.

 

 

Superior quality electronic volume control for optimum sound

We’ve utilised a high-quality digital volume control specially designed by New Japan Radio Co., Ltd., which consists only of ladder-type resistance, removing the impact of slew-rate decline or colouring of the sound, delivering higher purity in the sound, and excellent, fast response to large volume changes and steep transients. Moreover, the tone controls employ a triple-parallel method, minimising the detrimental impact on sound quality seen with straight-line tone controls. In addition, the bass, treble, and common circuits each utilise simple construction in which the NFB of the amp is not used and the CR elements are simply fixed in a straight line, ensuring exceptionally pure sound reproduction even when tone control is applied and superb response to audio signal transients. When tone defeat is applied, straight signal flow from only one volume circuit to a discrete configuration buffer amp is realised.

Do these new Yamahas have loudness buttons/knobs?

 

No, just a -20dB mute switch.

That's interesting, since the A-S501, 701, 801 all have a loudness contour control. But they don't get the power or the cool meters. :D

 

Very, very nice looking amp!

There was a time I wouldn't have considered Yamaha for a 2 ch system, but I would now. Many good things have been said about the unit you bought. Looks like a good decision for you. Way to go!!
