    • Yamamoto Soundcraft YAD01 DAC
    I finally received my Yamamoto YAD01 Dac from Japan. This Dac was recommended to me by two of our Audiogon members; Charles1dad and Grannyring. It’s a very simple solid state Dac with only one RCA digital input, and two RCA outputs. As soon as I attached it, I heard improvement with additional detail, better imaging, more natural sound, better bass slam, and greater PRaT. The Audio Research Reference CD 7 CD Player I use is good, but this YAD01 put it over the top. Down the road I'll replace the caps in the YAD01 with something better such as the Jupiter Copper Foil 1UF 600DC, and replace the fuse.

    • Audiodharma Cable Cooker Anniversary Edition 3.5 CCGR
    Technical Discussion From Website: Although it is not yet fully understood scientifically, the phenomenon of “cable break-in” has been experienced by many audiophiles. Interconnects, speaker cables and even power cords seem to go through a conditioning period when used in an audio/video system, and will sound better after many hours of in-system use. The sonic differences between wiring that is broken-in and wiring that is not are very audible in high quality audio systems. The break-in process is believed to be due primarily to current flowing through the conductors of wiring components. Dielectric stress caused by a voltage difference between the conductors is also believed to be of some benefit. The fact that it takes many hours of in-system use for wiring components to break in is primarily due to the low-level nature of audio/video signals from normal program material. As an example, let us take an interconnect used to connect the output of a preamplifier to the input of a power amplifier. The typical maximum signal level for full power output of the average power amplifier is 2 volts peak. The average signal is much less. The typical input impedance of a power amplifier will be 10k ohms at the (very) low end for consumer gear—47 to 100k ohms is typical for a solid state amplifier, while several hundred kohms is not unusual for a tube power amplifier. Taking the (unrealistic) best-case values from the above examples, the maximum current seen is 2 volts/10k ohms = 200 micro-amperes … and this would not be continuous current, as the voltage value is a peak value, not an rms value. For the sake of demonstration and comparison we will describe a “use value” consisting of the current flowing through the wiring component according to the above equation, multiplied by the total time this current flows. We will refer to this use value as CTV, or “Current-Time-Value”. Playing an interconnect cable in an audio system for one week (168 hours) of continuous use would expose it to the following use value: 168 hours x 0.0002 amperes = CTV of 0.0336 The CABLE COOKER™ was designed to produce signal levels far in excess of those seen in normal audio/video system use. Internally, the device contains a sweeping square wave oscillator that drives a very high-efficiency “H” bridge MOSFET switching circuit. The output signal includes a swept square wave calibrated from 0 DC to over 40KHz (plus harmonics). Output voltage is 12 volts rms. The current through the wiring component is determined by the load at the input connector of the CABLE COOKER™. In the case of interconnect cables, the measured current is 120 milli-amperes. Installing an interconnect on the CABLE COOKER™ for one week results in a CTV of: 168 hours x 0.12 Amperes = CTV of 20.16 This is a value 600 times greater than that obtained under the most ideal of audio system conditions. The “stress” on the dielectric of the interconnect is also much higher than in normal use due to the higher output voltage. It should be readily apparent why results with the CABLE COOKER™ are often quite audible after as little as 24 hours of use. The same powerful signal described above is also produced at the speaker cable output binding posts. The load at the speaker cable inputs, however, is designed to draw a continuous 1.88 amperes of current through the wire. With a potential of 12 volts, this is equivalent to a continuous signal level in excess of 22 watts!! It must again be emphasized that this is a continuous condition (i.e., rms). This extreme continuous-signal level, produced in an audio system in a regular listening environment for any length of time, would force us from the room due to the highly uncomfortable and intensively-loud volume. One can now correlate the impressive signal level produced by the CABLE COOKER™ and the benefits derived by its use with the cabling in our audio/video systems.
    • Square D Surge Protector HEPD80
    After doing some research I decided to purchase the “Square D Surge Protector” My purpose is to protect my entire home. appliances, computers (stereo system) etc. incase of a lighting strike etc. This device wires into your main electrical outlet box ideally at the top into one or two 20 amp circuits. Directions are provided, easy to follow and the job can be completed in 20 minutes or less. This product lists for $160 but can be purchased from Amazon for $86. Incase of a surge including lighting strike the unit would need to be replaced and the two green lights on the unit would not be on. See my main system for additional pictures of the Surge Protector seek; Lak's Music Room 2014.

Hi Lak,
I applaud your wise decision to keep the Yamamoto, hang on to this gem😄


I'm somewhat surprised you sold your Yamamoto given how much you enjoyed it. Any way good luck with your next DAC project, keep us posted on your progress.


I'm somewhat surprised you sold your Yamamoto given how much you
enjoyed it. Any way good luck with your next DAC project, keep us posted
on your progress. Bill Im curious about your thoughts on the DHT DAC once
you acquire it. We both admire DHT components when implemented well.
At one time I had interest in the Lampizator Big 7 DHT DAC. No doubt it's
very good( heard at a show) but I just decided the Yamamoto sound quality
keeps me happy, so why change?


Thanks Lak. Did your modifications include the Jupiter copper foil capacitors? To describe an audio component as "natural sounding" is high praise and this isn't an easy accomplishment. In the current High End lexicon, I prefer natural rather than what's described as accurate. Presently these two terms result in different types of sound character. If component A is said to be natural and component B is accurate, I'll choose A.


Hi Lak,
I look forward to reading your comparison of the two DACs. I placed Duelund CAST capacitors and a SR Quantum fuse in my Yamamoto. The effort was worthwhile, however the completely stock Yamamoto is excellent and natural sounding. The changes I made take it up a notch but isn't a night/day improvement. Probably because the stock DAC is so well implemented in the first place.


Hi Lak,
You've obviously have put considerable time, thought and effort into your audio system. I imagine that it sounds fabulous! I'm glad to see you bought the Yamamoto DAC and that you're very pleased with it.
