Bi-directional USB 2.0 Audio Class consistent port is locally upheld by OSX and Linux without the need for drivers I also think its separate chassis design looks really good. They have done a very good job with the design. The starting point is to establish input and output reference levels at 1kHz. This means setting the AF signal generator to –20dB out (0dB being up to 10V maximum), and the fine control for an output of 600mV. This is reduced by the 100:1 attenuator to 6mV at the input, giving 400mV at the output – these values were chosen just for the sake of getting round numbers.

WIMA and the later one a 1.0 uF Jantzen Silver Z for the output coupling. Unless you need to drive a low impedance (below about 10k) preamplifier the 1 uF output capacitor is quite sufficient to allow response down to the 20 Hz range. Another difference is the use of Gold Pin JJ ECC83S tubes in place of the JJ ECC803S. The JJ Gold Pin ECC83S tubes were about 1 to 1.5 dB quieter. This helped me reach the -90 dBV level of noise I sought. The above feature also allows more passage of current along the circuit which further enhances the sound quality Gauging the qualities of the PS3’s sound was simple compared to many others that hide secrets in their topology and nooks and crannies of uneven soundstages. The PS3 was a straight shooter. Enviable imaging, wonderfully wide and deep soundstages with timbral accuracy. Phonostage aficionados will recognize the tubey goodness immediately.But like all wonderful tube phonos, they marry beautiful timbre with admirable clarity. Tubey it is, tubby, it’s not. This means that a phono preamp’s work connects a record player to an amplifier by adjusting the phono signal to a standard line level.Having owned a Croft Phono Integrated for a number of years, I knew what to expect from the RIAA Phono unit, but also expected more from the more expensive standalone unit and was ultimately not disappointed. After many months of researching tube phono preamps, I finally bought a Pro-Ject Tube Box S2 to use with my turntable, and it has been my reference phono preamp ever since. This article essentially sums up the research and selection process I went through when buying a good tube phono preamp for personal use. The Yaqin MS23B Tube Phono Stage is a worth buying product that gives a smooth and distortion-free sound. Pro-Ject Tube Box S2 Phono Preamp

I used mine with a Quad 909. I did need the gain reduced slightly in the Croft for a better match (something the dealer did gratis) but boy what an amp pairing. There are likewise a few monaural highlights, even an invalid parity. What’s more, the Puffin handles numerous old record EQ settings. Features

When you cut the built-in phono stage out of the loop, and replace it with something better, your vinyl will begin to reveal its true potential. A dedicated phono stage is easy to install: it sits in the signal chain between the turntable and any line-level input on your amp. A word of caution: Don’t take the output from your phono preamp and connect it to the phono stage on an amplifier, as that will double amplify the signal, resulting in catastrophic distortion (which isn’t as good as it sounds). In an earlier build I wanted to have the capability to do mono records as well as stereo. So I included a switch that connects the two channels at the input (shown in the photo below of an earlier build). This Little Dot MK II Tube Preamp includes propelled functionalities to perform better amplification. This gadget is likewise a perfect preamp in the tube preamps category for beginners.
