Cordless Vacuum 20 Amp

I bought the amp for the following reasons: 1. It is made in the USA; 2. It is vacuum tube based, pure class A amp; 3. The price. I have replaced the stock tube with a Mullard re-issue tube and let it bake for the total of 24 hours. I use it with HiFiman Sundara, Vincent integrated as the tube pre-amp. The sound is very balanced, non-fatiguing but not excessively tube-warm. It's a pleasure to listen to for hours. Highly recommended.

Amazing little vacuum/blower!

makes dust and debris disappear. Can't vacuum.

Vacuum packed cartridges for the longest possible life.

Was a bit frustrating at first, as I have never used a cordless printer before!

Replacement batteries for Panasonic cordless phone.

Cordless charging what more could one ask for. So far so good

Good for quick cordless shooting

Despite the fact that these cans have been on the market for 20 years, they still set the benchmark for mid-priced audiophile headphones. They excel in many areas, including a vast soundstage, pin-point imaging, gobs of detail, and tonal neutrality. They communicate music beautifully and they are very comfortable for long listening sessions. They will sound much better after about 20 hours of use, so don't base an impression solely off a demo of a new pair. However, I do recommended them for everyone. They have a very flat signature, so they are not for bass heads. Also, they are very transparent and you will hear everything upstream. They will not mask any flaws in your equipment. In addition, they absolutely require a headphone amp. The little op amp in my CD player does not do the job. I'm using a Shchiit Magni 2 and quality cables. The little piece of Schiit does a perfect job of powering these cans at the right price. Love em.
