Highend phono preamplifier

Reference class phono preamplifier with unique impedance control

This ultra low noise and distortion preamplifier is made for the audio conniosseur and offers not only breathtaking performance but is capable to adapt to virtually any phono cartridge through variable impedance control. Impedance adjustment can be done while playback! Due to use of best parts, like SSM2019 from Analog Devices as input stages and Linear Technology LT1010 as high current buffer stage, Phono Box RS delivers ultra low levels of distortion and noise. Its very low output impedance makes it insensitive to selection of interconnect cables and lenghts.

Fully passive RIAA and DECCA equalisation is selectable. Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. All in all vinyl playback will never have sounded as clear, detailed and smooth, than with this superlative phono stage!

  • True dual mono design
  • Balanced XLR & unbalanced RCA In & Outputs

  • Classy & elegant dip switches

Our dog loves this toy so much we bought her a second one!
Size: Large, Size: Large
This is absolutely the best dog toy! Our girl has destroyed just about every other toy we have gotten her, but these have lasted 4 months with no sign of damage or wear (just lots of dirt!). She always has one of these in her mouth (occasionally both when she manages it). They survive tug of war, they are great for throwing, and even better for kicking. Have two is super handy for alternating which ball you kick/throw. Super glad we found them - I can't recommend them enough!

Just 1 toy!
Size: Medium
We have a big dog and a small dog. This is a perfect toy for both of them. However, my low rating comes from the seller. The ad description showed two balls for just under $15. (What a deal!). I received one ball….. and when I went to look back, it does in fact say much lower in the description “ you will receive one of these two color options” Generally, if they’re just showing you color, you have a choice in this case I did not have a choice and I find the post with two balls very deceiving! Five stars for the toy one star for the seller equals three stars

Better than the others
Size: Large
I was in search of a ball that would hold up after the brand I’d bought for years suddenly lasted less than a month. This one is almost 3 months in use. Some damage done after playing with it almost non-stop, but still going.

Aggressive chewers have met their match.
Size: 10.5 inch Rubber Flex Tread
We purchased this toy in 2022, it finally broke last night. Four years of rough play with 2 boxers who are aggressive chewers. They would tug together, gnaw on it for hours, and often leave it outside exposed to the elements, but this toy just kept going. It was by far their favorite toy, it kept them busy for hours. I just ordered a replacement. Well worth the money, perfect size. Highly recommend.

Durable, fun, and safe for my dog
Size: 10.5 inch Rubber Flex Tread
I have a 10 month old, 50 lb mutt who has the musculature of a pit bull and the muzzle of a GSD. Buttercup’s favorite past-time is shredding toys into teeny tiny bits, but sometimes those bits don’t come back out of her mouth. She can’t have tennis balls, stuffies, anything with a squeaker, silicone toys, plastic toys, rubber toys with spikes or small appendages, anything with rope, or most chews & bones. She chewed her first and only $8+ XL bully stick like a corn chip. Finding indoor enrichment is a challenge. Buttercup is extremely pleased with this tire tug thingy, it is very ergonomic for both her and me to get a handle on it, it has more movement than any other toy she can safely have, and it’s very durable. After more than a week, there’s only a little bit of tread missing, which is definitely the best-case outcome with a super chewer. I think this is a good alternative to GoNut toys because it’s solid & dense while also a little bit easier & more interesting to play with, and very unlike GoNuts, this Tonka toy is very reasonably priced. I also think this it’s a good size for almost any breed of dog—I could definitely picture a little Boston or Frenchie dangling from one end. Highly recommended!
