A full model change of the middle level vacuum tube output driver unit

STAX introduces a new vacuum tube output driver unit “SRM-500T”, the successor model of “SRM-006tS”. STAX custom-made low noise DUAL FET is installed on First Stage and the vacuum tube”6FQ7/6CG7″ is installed on Output Stage. STAX continued to use the traditional circuit design which is perfect for STAX vacuum tube driver and improved the power efficiency. Finally SRM-500T achieved the sound quality improvement.

In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-500T. The low voltage winding enables to improve the power efficiency and achieve further power saving and better sound quality than the conventional vacuum tube output driver units such as SRM-006tS.

The new chassis which is more rigid than the conventional model is installed. The chassis has a hybrid structure using a lot of non-magnetic aluminum and further reduces the effect of the environmental noise factors such as vibrations. The inputs are RCA and XLR, the mutual exclusion inputs. The custom made concentric dual volume knob which is common to STAX products and RCA PARALLEL OUT functions are installed same as the conventional driver units. All electric components are strictly selected considering the environment. Also the sound quality and the performance is improved. The complete DC amplifier configuration that the signal circuit includes no coupling condensers is one of the biggest traditional features.

The clear and highly transparent sound, a feature of the vacuum tube circuit and the warm and wide sound texture is maintained and the thickness of the low-mid range is brushed up. This is the new choice for the combination with the advanced lambda series (SR-L300/SR-L500 MK2/SR-L700 MK2).

Great Shirt, Awkward Shoulders
Color: Light Grey, Size: X-Large
I want to start off by saying, I really, really like this shirt. The fabric is spot on: soft, comfortable, not too thick, not too thin. Honestly, it feels like it was made by someone who understands the Goldilocks principle of clothing. So why only 4 stars instead of 5? The shoulders. I ordered my usual XL, and while the rest of the shirt fit great, the shoulders were so tight I felt like I should audition for the role of the Hulk. I exchanged it for an XXL, and now the shoulders fit perfectly… but the rest of the shirt feels like it’s training me for a parachute jump. If it weren’t for that one sizing quirk, I’d swear off buying any other shirt ever again.

Quality for price

Beautiful color, great fit! Has a nice feel to it worth investing in more colors🙂slightly wrinkled but an iron or steam will probably take those out, has a softer feel to the fabric
