Golden Age Project Pre-73 DLX by tribedescribe
I owned the original mk1 version and sold it last year. I liked it a lot on certain things but found it slightly noisy and not as clear in the high end with certain sources. Although at times I really liked that fat sound on some sources like bass, guitar and vocals.
Fast forward and I bought the DLX version with the power supply. Right away I noticed the noise is gone and high end is a little clearer. This version is similar to the mk2 but features the TT mod as a stock addition in the DLX version. The Dlx version also adds a high pass filter and and a output pad to drive the transformers. At first glance I thought it was just a pad but upon using it I quickly realized this is the best part of the DLX. I found driving the input of the mk1 version to much yielded in a unpleasant fuzz overdrive. The pad on the output is designed to drive the output transformer also. I find this a much more pleasing sound allowing me to balance the gain stages and coax and bit more drive equally from each transformer. This yields way more tonal options than the original and makes it much more versatile. Using the D.i. on bass or guitar make my Guitar rig program sound way better.
I think the original is still a great bang for your buck unit. But I have to say the DLX version is also worth every penny and offers much more tonal options with the output pad. You really cant go wrong with either. I think the DLX version also adds better vintage spec wiring and a 600ohm switch which I always keep engaged. On a side note I downloaded the audio files on the SOS site which compare the DLX stock with a DLX with carnhill trans. , I have to say I did not hear a big difference with my Bose in ears except that the heavily driven bass sounded more focused with the mod. Clean to slightly driven setting's sounded exactly the same. To me the upgrade is not worth the cost. Your mileage may vary.
