Dear Record Collector
Dear and appreciative music listener of authentic vinyl LP recordings, welcome to my pages.
Over the years I have collected many records. In many instances they formed the basis for my pages, for study and research. And many were bought because I did not have the chance to acquire them in the years before because my focus was first on my job in advertising, in designing and copy writing.
Now they have become too many to keep them all. Therefore I will sell items of my well maintained collection, items that may be of interest to you. I wish you happy browsing.

At the moment the records are evaluated on this system:
Preamplifier is NAD C165BEE, a neat sounding and dynamic preamp. This preamp is connected to a McIntosh MC2105. The main turntable for evaluating is the first Technics SP-10 known as 'Technics by Panasonic' with
Rabco SL-8E tangential tonearm and Philips GP 422 II cartridge which goes very well in the Rabco. An aternative is Audio Technica AT12XE cartridge equipped with the generally admired Shibata stylus ATN12S, There are more turntables in the collection using a variety of tonearms and cartridges. The Technics SP10 Mk2 with Technics EPA 500 tonearm and mounted on a slate plinth (with a Philips 420 cartridge) is there for a second opinion.
A second turntable is a Garrard 301 with SME 3009 tonearm and Ortofon VMS20E. There are alternatives of various makes available like Ortofon MC cartridges, newer models of Audio Technica, Shure (various V15 cartridges). The Garrard 301 is connected to a ART Pro Phono USB the signal of which goes into the Tuner input of the NAD.
All connections are by the same 'simple' but very musical interconnects of a brand made in China.
The digital signal coming from the main desktop PC is translated by the Audioquest Dragonfly USB DAC. The signal of which is also connected to the NAD. Loudspeaker cables are Audioquest CV-8 of 8 ft length. These are great cables.
Many audiophiles and also music listeners are well aware of the necessity of clean current to feed the components. There are various power conditioners on the market starting at a few hundred dollars up to thousands of dollars for the ultimate transformer that regenerates a completely new and perfect whole sine wave. Reviews for the low priced items are not always too positive. This also goes for the Isotek Dynavox x4100. Nevertheless I bought two of these in the spring of 2021. And to my surprise the reproduced sound of my system improved notably. A further step was brought about by two heavy power cables, a fancy one with red and gray braided finish and another heavy one with a grey and white, more neutral finish. They give an improvement of the sound: better harmonics, extended frequency band and spatial imaging. I will publish an elaborate review on my Audio and Music Bulletin later.
A pair of JBL 4312A Monitor Loudspeakers has been refurbished with new drop-in cones (including voice coils and corrugated surrounds) made by JBL. After that the 4312A cabinets were fully optimized over a very long period of time while carefully determining the amount of damping material in the woofer compartment and adjusting the material in the cavity for the mid section driver. The surround of the woofer and the surround and cone of the midrange were treated.
The opt5imization of the system has to be done while fully taking the performance of the woofer in its own compartment into account. Finally it is important how to position the speakers in the room to achieve best results.
JBL 4312A and other types are not easily obtained in Europe. My pair was second hand and came from the US. For those who are interested in the qualities of JBL speakers it may be interesting to check the
Kenricksound website in Japan, choose the language and listen to the sound quality of the various loudspeakersystems they have for sale on their website and on YouTube.
