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).

The perfect casual layer—unbelievably soft!
Size: Large, Color: Burgundy
I am seriously impressed with this hoodie. It’s made from a lightweight jersey material that feels just like a broken-in, high-quality t-shirt. It’s perfect for those transitional weather days when a heavy fleece hoodie would be too warm, or for just lounging around the house. The fit is spot on—not too baggy but with enough room to move comfortably. It washes really well without shrinking or losing its shape. For the price, you absolutely cannot beat the value. I'll definitely be buying a few more colors!

The Perfect Hoodie for Warm Weather Comfort
Size: XX-Large, Color: Black
I've been on the lookout for something exactly like this... a hoodie with the look and feel of a sweatshirt, but without all that heavy fleece that can become uncomfortable when temperatures rise. This Amazon Essentials Lightweight Jersey Pullover Hoodie turned out to be just the solution I needed. Right out of the package, I noticed the material felt soft and airy, like a premium-quality T-shirt rather than a traditional hoodie. The lightweight fabric hits just the right balance: thin enough to remain cool and breathable, yet substantial enough to give you that hoodie vibe you're after. This makes it especially great when the weather is too warm for your thicker hoodies but still a bit too breezy for just a tee. The fit is exactly what I was hoping for... comfortable without being baggy, and relaxed enough to allow easy movement. It drapes nicely, so it never looks awkward or ill-fitting. The hood itself is perfectly sized—not overly bulky, but still practical if you need a bit of coverage. No shrinkage when washed and didn't fade. I've found this hoodie to be ideal for casual days around town, lounging, or even traveling. It layers well, making it versatile for spring, early summer evenings, or warmer fall days. If you're looking for something comfortable, lightweight, and stylish enough to pull off the hoodie look in warmer weather, this is absolutely worth picking up.

My new favorite hoodie!
Size: XX-Large, Color: Charcoal Heather
I love this, this is my new go-to hoodie! It's very soft and breathable, it's roomy and comfortable, and it's not too heavy. I've washed it a few times and it's held up well. For the price, you really can't go wrong. I'll probably end up buying a couple more colors.

Sleeves are too short
Size: Large, Color: Black
Good quality about as thick as heavy t shirt. The only issue is the sleeves are a tad short which is a bit disappointing. Not sure I will buy this again. I’m 5-7 175 and ordered a large and it fits well. Just a smidge oversized like I prefer.
