Boulder Amplifiers 2150 mono amplifiers custom pair insight part 1


First part of the journey of Boulder Amplifiers custom pair of black 2150 mono amps through the factory after most of their assembly. This photo shows one of the amps prepared for testing. You’ll notice three things are missing: the top cover, the front panel and the feet. They don’t install those parts until the amp has been through all of its testing and listening in order to protect the most visible pieces from any cosmetic damage.

During assembly, the amps are built from the ground up and inside-out. The transformer case is attached to the bottom plate, the rear panel is in place and the surrounding circuitry installation begins. More follows…

PCM, SACD and DVD-A intriguing facts


Dietmar from Trinity Audio explains some of the intriguing facts about the PCM, SACD and DVD-A...

The problems with PCM came up with the introduction of DVD-Audio. Even it was the better data format by default than DSD it was so bad implemented in consumer products.

I bought a Meridian DVD-A player (7500USD) and was surprised about the bad sound. Actually I was looking for a DVD-A drive, which I could “upgrade” with an own high speed digital output for my first TRINITY DAC.

So I had to measure a lot on at least a dozen DVD-A players from Denton, Meridian and so on.

Analyzing the Meridian player has shown, that the drive down- samples all original 192kHz tracks to 96kHz and feed this data stream to an Analog Devices DAC IC, which up-sampled the data stream again.

What a stupid implementation and that from a company, who was part of the standardization with its MLP ( Meridian Lossless Packaging). You got more and useless signal processing than in a CD player.

No wonder that people got disappointed playing DVD-A even using expansive playback devices. 

Another example, it took for me a few days working on the flag ship DVD-A player from Denton, before I found a setting where the 192kHz data stream was not down sampled. But for that you need the service manual and a logic analyzer to understand what they have implemented. The amazing thing was, that the key point in the setting was in the video menu and not in the audio menu. Means only with a dedicated video setting you could get the original 192kHz audio data stream. 

Chisto Easy Groove impressions


Chisto Easy Groove has two types: the immediate Spray and Wipe, and the Concentrate. The immediate Spray and Wipe is to be used as the name suggest. I tried it on a number of new sealed and used LPs, I found that it immediately gave a clarity and improved detail over all presentation. You will and can hear the effect.

As for the Concentrate version, I tried it against the other liquids in hand, The Disc Doctor and MintLP, I prefer the Chisto. The Chisto does not leave a shine on the LP as the Disc Doctor will. The MintLP tends to make the cleaned LP to sound a bit veiled (to my taste). The Chisto is able to bring out more clarity and detail out than the above mentioned liquids. I can hear inner detail being brought out to light. The dynamic slam is more taut and faster. 

Of course, I realized the Chisto Liquids do not bring out what is not there in the grooves but they made me realized how much I have missed without them… enjoy

Transfiguration Proteus MC cartridge


Transfiguration Proteus MC cartridge has entered. To showcase the Dr.Feickert Analogue BlackBird turntable at another level, the kind folks at Audio Note Singapore have sent in one of their best selling MC cartridge for the review. I have no complain over the Ortolan Cadenza MC cartridge that was in the initial set up that I considered to be a fine performer, but I could not refuse the opportunity to hear the Proteus.

The initial impression of the addition of the Proteus was how true the positive review is. I read back the review written by Michael Fremer at Stereophile and I said to myself, I agreed. 
Then I realized that the Blackbird turntable is a good turntable to have allow the change of cartridge to be so obvious and all that are reported in the review can be heard…enjoy

Orpheus in the higher region


Our friend Audio16 boys takes us back to the Sennheiser Orpheus heaven…

Some 20 years ago during my stay in Japan I was listening with Stax electrostatic headphones and I liked it. Back in Europe I was much more concentrating on my system & speakers and of course on everything dealing with Phono! Having built up a dedicated small bedside headfi unit I was intrigued by dynamic headphones like the ones of Ultrasone or Beyerdynamic.

Occasionally I heard about the Sennheiser Orpheus headphone system – the big amp and the fantastic HE-90 headphone being produced in the 90ies. Sennheiser came out with another electrostatic unit in 2005, the HE-60 (also known as the Baby Orpheus). However, the drivers are electrostatic and thus require an electrostatic headphone amplifier. The bypacked HEV-70 mobile amp wasn`t really an ingenious wonder…you see it on the image in the background.

As I knew the Stax Headphones differ in sound quality – some say the older Omegas II with lower numbers (SZ1) are even better than the new ones- I was intrigued by the possibility using a Baby Orpheus in combination with an electrostatic amp. So I went for a HE-60 unit with brand new drivers, new rubber elements and earpads. An upgrade Stax cable with Pro 5-pins and an dedicated resistor of 4,7 MOhms came with it.HE-60 -1

Having had the chance now comparing the HE-60 with Stax headphones on the connected Stax SRM-007tII amp I believe they are different sounding headphones. The HE-60 is much more forward than the Stax headphone SR-007 e.g.The HE-60 has a faster attack due to a little brighter signature. When you hear the drums on the recently published Live CD of Manu Katche you will agree with me that the HE-60 provides naturalness, subtlety, texture and layering of the sounding in
