Acoustic Research AR91 Speakers

Now these are some serious speakers.  While they don't hold a candle to their bigger brother, they still produce a fine sound signature.

The AR91 are floor standing speakers in a 3-way acoustic sealed design.  It features AR's 12" woofer, it actually measures out to be 11", dome midrange and dome tweeter.  If you're looking for big and detailed sound, these are a fine pair of speakers.

They are pretty big but, not super large and they are well designed having that real wood veneer and unique shape.  The grills are also bowed out at the bottom, so they are quite elegant to look at with some serious sound behind them.

The woofers have been freshly redone and still need to be broken in.  The downsize of these AR91s are that they are power hungry.  They aren't really efficient and they love clean dynamic power.  So, no they aren't really tube friendly unless you have some serious tube monoblocks.  They are also 4 ohms and need something with a good transformer. 

They are quite heavy, but when I was servicing them, the woofer weight was one of the reason why they're so heavy!  Beefy magnets on those woofers. 

For their sound signature they are darker sounding than what I normally listen too.  They are the Sennheiser of speakers.  If you are familiar with Sennheiser headphones the AR91s have similar sound signature.  Hence, why I would recommend a brigher/dynamic amplifier to balance the sound to my taste.  They have superb bass.  They are quite detailed with a lovely midrange and can fill a room nicely with beautiful music.  I just can't stress that you need a very good amplifier to drive them. 

Overall, they are in excellent shape!  Only flaws is the dampening foam on the midrange and tweeters have stiffen due to age.  However, I was lucky to find they still came with it.  So, if you got a powerful amplifier and need some great speakers that have a bit of WAF appeal, these might do!

Micro Seiki MR-622 Turntable

This is one of my greatest prize possessions, well for turntables.  The Micro Seiki MR-622 is a fabulous turntable, and definitely has been one of my favourite tables that I had the pleasure of owning. Everything about this turntable screams quality.  Even the 45rpm adapter seemed to be milled aluminum.  It has adjustable feet, a side pocket for accessories , a nice heavy die cast platter and even the top part of the plinth is cast.  All wrapped in a beautiful smoked dustcover and real wood sides. The Micro Seiki MR-622 is a fully manual, 2-speed, direct drive turntable.  This means, it's low maintenance and high reliability as there is less moving parts within the turntable.  It's just a huge motor, speed controls and Micro Seiki MA-202 tone arm, placed in a overly built plinth just like what one would expect from Micro Seiki. The MA-202 tone arm is a S-shaped tone arm with excellent tracking ability.  It has an adjustable counterweight and the...

Yamaha YP-66 Turntable

The rosewood vinyl wrapped twin sibling of the Yamaha YP-221, they are the exactly the same other than the colour of the plinth and instead of silver plastic bits on the YP-221 the YP-66 has black bits. This is your typical belt drive turntable of the mid to late 70s.  It's a 2-speed with automatic return (semi-automatic).  It's a nice entry level turntable with all the decent built quality that you find on majority of the Japanese made tables of that era.  It has a good sized motor and a decent weight.  Yamaha tables are like Sony tables, they always have decent quality components and they always look nice to the eyes.  The slight smoked dustcover and the rosewood plinth makes it quite unique to look at. Sadly, the antiskate weight on our isn't original.  It was missing when we got it.  After a bit of research we found the appropriate weight and found an appropriate weight to retrofit into our table.  We found a nice brass weight to fit with ...

Sanyo TP-1020 Turntable

That's right, I got myself a Sanyo! It's actually not a bad unit when you start stripping it down. I know, the overall black motif isn't awe-inspiring but, it is quite the performer. It's definitely better built than some other turntable I've come across. The motor, especially, is quite good. So, what can I say about this Sanyo? Well, it's definitely a CEC built table. Apparently, it as a twin called the Grundig PS-1020, tonearm looks different but, probably performs the same. It's your typical Japanese made direct drive turntable, 2-speed, pitch control and automatic return/reject (semi-automatic). It was a quite easy to work, everything was laid out nicely and everything was within reach to get too. Definitely better built than some of the Japanese turntables of the late 70s and into the 80s. I think one of the more common features with the Sanyo is the mirror at the base of the platter. It's an inspection mirror for the needle and I like it! I f...
