Space-Tech Lab. EAT-100 (Easy-Audio-Tester) for every audiophiles, DIYers, technicians and engineers From bonnyan in Nov 27, 2017Nov 27, 2017 From bonnyan
The EAT-100 Audio tester with its Tube tester add-on have helped me in making crucial decisions regarding my audio equipment line up. Tweaking the line up as mentioned below has immediately resulted in discernible improvements in the sound stage. In particular the Audio tester EAT-100 helped with decisions regarding which amplifier to use for driving the tweeters and the midrange and which one to use for the woofers in my bi-amp setup. The Frequency Response test was particularly helpful in finding the low and high frequency build-up and roll off points of each of my amp. My bi-amp consists of a tube amp and a solid state amp. Through the EAT-100 I realized that the tube amplifier has a sharp rise starting at 40 Hz going to 100 Hz and at the other end of the audio spectrum rolls off at 45 to 50 kHz to -3 db levels. I found out that the solid state amp is capable of going lower, in the 20 Hz range and rolls off at 80 to 86 kHz. Knowing this has helped in deciding which amp to use for which drivers. Also since I have super tweeters that go way beyond human hearing range to beyond 150 kHz it’s easier to decide which amp to connect them to for maximum benefit. Before I purchased the EAT-100 it was a trial and error process. Relying on feelings, going back and forth between the two amps never knowing conclusively. This because the quality and type of music played varied making objective decision making difficult. The quality of recordings is usually an unknown quantity – since while they may be FLAC or WAV files it is also the recording quality that plays its part, of which one is usually not aware of making it difficult to know which amp played better highs (treble) and which played better lows (bass).
As for the Tube-tester add-on it was more of a convenience for me as both my amp and pre-amp are of the zero negative feedback type and so I could have tested the tubes via the EAT-100 alone, but the add-on makes it way more convenient due to portability (on a table), faster and safer since I do not like hot swapping tubes (removing them with live current flowing) while they are in my expensive amp or alternately switching the amp on and off for removal/insertion of tubes again and again does not appeal to me. For those whose amps have negative feedback loops I suppose than the tube-tester add-on is a must or a full-fledged standalone tube tester which would be even better but more expensive and unnecessary for the average audiophile.
Space-Tech Lab. STR-1002-Mk2 with switchable choke upgrade From bonnyan in Nov 22, 2017Nov 22, 2017 From bonnyan
It has been a pleasure dealing with Albert right from the initial specification phase to end of the building process of the Super Rectifier STR-1002-Super. He was flexible, incorporating changes as required along the process and kept me updated as to the progress with pictures and answers and questions. Now that I have the STR-1002-Super it is bringing me great joy. It has made my already good system which comprises of the award winning DECWARE ZEN Mystery Amp and DECWARE CSP3 pre-amp bloom to their full potential. I will be surprised if I can get more out of them after this upgrade. The STR-1002 replaced the 5U4G tube in my CSP3 and the improvement was palpable to say the least. Within minutes it brought involuntary smile to my face coming to realize that purchasing this was a good call. As most audiophile do I have spent similar amounts of money on power cables, speaker cables and high purity silver interconnect cables and they all did improve my audio experience, but I would definitely say that adding the STR-1002 was more of an improvement than each of the others. I now hear for the first time vibratos in a singers voice that I did know existed in music that I am well acquainted with. Each instrument from the cymbals to the drums and everything in between are well differentiated and more life like. Familiar complex orchestral music that I have been listening to for years seem to have some additional complexity that did not exist before. In short the SRT-1002 brought to light details that makes it more natural thus making it more pleasurable.

I'm very pleased with the pre-amplifier. It has a wide open sound stage, high resolving power, and an emotional presentation. It's also a very good value. Al of Space Tech provides outstanding customer service and support as well.
