Tannoy Mercury M2 Speakers

Another deal I could not resist is this "Best Buy" rated entry level pair of Tannoy speakers. Not the dual concentric or horn loaded Tannoy's but a budget conscious offering.

Another British designed and built speaker once again using a 6 1/2 woofer and a textile dome tweeter, this speaker has a beautiful cabinet and is very well built.

Not the super efficient Tannoy Oxford Gold that has become my reference speaker connected to the tube amp, but a surprisingly good little speaker that produces amazing bottom end and a clean clean sound.

Not the highest efficiency and the mi range is a little laid back but non the lesss a great speaker and tops all the other speakers in its class that I have sampled on this blog.

Aesthetically these are little beauties and have a high wife friendly factor.

There is plenty of info and reviews on these speakers on the internet, well impressed and very deserving of their "Best Buy" status for under 250 Pounds Sterling.

Wharfdale Delta 30 Speakers

This entry level Wharfedale Delta 30 came my way this week. A nice little 6 1/2" woofer with a textile dome tweeter.

This speaker is a pretty good offering sound wise although the lime green motif is not my favorite. these speakers are very neutral and a little shallow in the bass department. Women vocals are smooth and the sound is very British, very good in the mid range. Imaging was good for their size.

I am sure these competed well against the B&W DM100i, the Mission 700 Leading Edge, EPI A70 or the Acoustic Research AR 18B featured on this blog before. My favorite out of the bunch is the Acoustic Research AR 18B.

Now that I have the Rotel RX-830 back from repair these speakers would match up well with a British designed amp for a starter system.

Kenwood KR-9400 Receiver

A Kenwood monster from 1976, the KR-9400 runs a 120 watts per channel and was one of Kenwood's top of the line receiver during the 1970's only to be superseded by the KR-9500 and the KR-9600.

This unit has a huge transformer with two 15,000uf power caps.

I look forward to auditioning this unit over the next few weeks.

Noresco NE 561 Speakers

A great find came my way in this pair of Noresco NE 561 speakers, these are Canadian made with a well revered Isophon PH2132E dual concentric Alnico 8"X12" woofer with a 3" tweeter center mounted.

This pair of speakers has a beautiful walnut veneer cabinet that was a little sun bleached but a few nice coats of Circa 1856 Naturoil brought out the best in the cabinets.

I have swapped to this oil versus Minwax as the Minwax off gasses for 48 hours and this product is all natural.

I opted to upgrade the internal speaker wire to 16 gauge and replace the tired caps with Solen Fast Caps and it has completely opened up these speakers.

It looks t me like Noresco built these speakers to Isophon specs according to the data sheet.

So how do they sound, absolutely amazing on the Single Ended tube amp. They need a little bump up in the bass region but the mid range imaging is incredible. The cone tweeter is nice and smooth without any paper harshness, almost horn like. The dual concentric driver really shines in placement of instruments and musicians, the sound from one origin source is a real joy to listen to, no wonder the Isophon PH2132 drivers are well sought after.

The efficiency is pretty high of at least 95db at one watt, which suits the tube amp perfectly.

I have become a real fan of well designed speakers that use natural roll offs and a single capacitor in the crossover, it means that the drivers were designed to work together and they are not off the shelf  drivers.

Speakers that do this the best are EPI 100's, AR 18B's these Isophon drivers, the Tannoy Oxford Gold's and the Sound Dynamic Concert 500's all have a 1st order crossover and they all sound best on a tube amp.

These Noresco'c image incredibly well as if they are a window into the music. If you are a tube aficionado these speakers should be on your list of must hear speakers. 

Paradigm Mini Monitor V1

Another and later version of the Paradigm 3SE Mini speakers that showed this past week is this pair of Paradigm Mini Monitors Version 1.

The Paradigm 3SE Mini's made it up to Mark 3 before being rebranded as the Paradigm Mini Monitor. A move to a polypropylene woofer was carried over from earlier versions of the 3SE mini but the Mini Monitor now has a titanium dome tweeter, replacing the Vifa fabric dome tweeter. the Mini Monitor is now sold in its' seventh generation.

I find the titanium dome to be smooth and crisp, revealing more detail in the music that the Vifa tweeter. The bottom end bass notes can be a bit boxy as the 6.5" woofer tries to fulfill its' duties. Where these little speaker really shine is from the lower mid range right to the highs, these are silky smooth with great depth of sound and really nice imaging.

To really balance out these speakers a sub woofer should probably be used with a crossover in the 100-120Hz range.

These speakers sounded nicer on a single ended tube amp versus the push pull tubes.

I have a feeling these speakers will be staying around for a while.

Paradigm 3SE Mini Speakers

Another pair of Paradigm 3SE Mini speakers came to visit me again. this is about the sixth pair of this wonderful speaker that has graced my aural pleasures.

This pair belongs to a friend of the blog and wanted to hear them on the tube amp. These are by far one of my favorite 6.5" 2 way speakers out there and well worth seeking out if in the market for a decent set of used speakers for a smaller space.

The sound way larger than they actually are and outside of being a bit bass shy they image great with spot on mids and highs.

I did do a quick re cap with a  4.7uf Solen polypropylene cap which improved the performance immediately. 

ADC 303AX Speakers

Acoustic Dynamics Corporation, ADC 303AX speakers came my way yesterday. This sealed 2-way speaker is right out of the early 70's and competed with the usual suspect including AR, KLH, Dynaco, Jensen and others.

 These speakers were built around CTS Alnico woofers and a CTS tweeter that also has a doped surround, before the infamous yellow phenolic ring tweeter.

The sound is very deep in the bass region smooth across the mid range and the highs were surprisingly crisp and clean with great dispersion.

Real walnut veneer cabinets are in good shape with all corners square, the usual Wabi Sabi* scratches are evident event after a light sanding and a coat on MinWax and I am fine with that. In fact I prefer Wabi Sabi to modern standards.

 These sound best through the Single Ended tube amp, in fact they sound fantastic, I am well surprised.

An old ad was found on the Audio Karma site from a discount store called Dixie's and you can see where they fell in the pack.

Generous gobs of the doping material have sufficiently cover the crossover that make the 6uf cap un accessible so I will just leave it as it is.

*Wabi Sabi: Japanese for the art of imperfection.



Broadly, wabi-sabi is everything that today’s sleek, mass-produced, technology-saturated culture isn’t. It’s flea markets, not shopping malls; aged wood, not swank floor coverings; one single morning glory, not a dozen red roses. Wabi-sabi understands the tender, raw beauty of a gray December landscape and the aching elegance of an abandoned building or shed. It celebrates cracks and crevices and rot and all the other marks that time and weather and use leave behind. To discover wabi-sabi is to see the singular beauty in something that may first look decrepit and ugly.

Wabi-sabi reminds us that we are all transient beings on this planet—that our bodies, as well as the material world around us, are in the process of returning to dust. Nature’s cycles of growth, decay, and erosion are embodied in frayed edges, rust, liver spots. Through wabi-sabi, we learn to embrace both the glory and the melancholy found in these marks of passing time.
