It took about 10 days to two weeks for them to arrive. Of the four tubes in the Freya, I replaced the right two tubes with the PSVANEs and used tube savers to raise them. There was a noticeable improvement in sound. It was a richer and broader sound over the Tung-Sol tubes that came with the Freya. It was very noticeable, and I was pleased. This was my first experience with rolling tubes and I decided to try more. I then purchased two Ray Tubes Select 6SN7 tubes. I put them in the two right sockets and moved the PSVANEs to the left. The Ray Tubes sounded nice, maybe they were slightly better than the PSVANEs, maybe. They were definitely more expensive. After a couple of days, the Ray Tubes developed problems. I sent them back, and the manufacturer sent replacements. During that time I ordered two more PSVANEs. They arrived, and I put them in the Freya, so all four Freya tubes were PSVANEs. It sounded great. Again I was very pleased and think they are a great value. Later, the Ray Tube replacements arrived, and I put them in the two right sockets (gain stage). So two PSVANEs and two Ray Tubes are installed. My system sounds good, and I'm happy. I don't think the Ray Tubes were worth more than the PSVANEs. The Ray Tubes might be slightly more "tubey" sounding... maybe. But if they die, I will replace them with the PSVANEs, so all four are, once again, all four PSVANEs. The PSVANEs sounded a little tighter and more accurate to my ears. I don't want to spend more on tubes than I spent on the PSVANEs. They sound great, and I'd rather invest my money in upgrading speakers or other things. So, I can report that my four PSVANEs sound great and are on par with the more expensive Ray Select tubes. I'd recommend them to anyone. My experience was good. Review: Believe the positive reviews! - PSVANE CV 181-AT HORIZON SERIES (6SN7) right out of the box is the best tube new or NOS I have heard in my Schiit Saga + pre amp. Usually swapping a tube makes a subtle improvement or no difference but I see no reason to look any further. The Horizon Series reviews are correct. I am over the top happy with this purchase. I bought the matched pair even though I only needed a single because that is the way desertcart currently sells them. Sound is subjective but I immediately noticed a balanced frequency response, a large sound stage, clarity and realism in vocals and instrument placement. Deep natural bass. Iā€™m glad I purchased and would recommend to anyone. ## Features - CV181-AT in the PSVANE Horizon series use Increased-Density ceramics for the base to improve on low conductivity and stability.

One would think PSVANE cared more about their merchandise than they do. Second pair were much quieter but still suspect. Waiting for a pair I ordered direct from PSVANE to arrive to compare before returning these. Nothing like going to the wHole Foods to dinf there is no on4e there until nine o'clock and when they finally get there they take forever to get things set up. I left in exasperation. These should NOT be purchased from this company unless you like wasting your time. Forgot to mention - the kiosk there for returns does not take printed out return forms - only from phones. Always an incredible experience. ## Frequently Bought Together - PSVANE Horizon Series CV181-AT / 6SN7 Vacuum Tube Amplifier Matched Pair (2 PACK) - PSVANE Horizon Series 300B-AT Vacuum Tube Amplifier Matched Pair (2 Pack) - PSVANE Horizon Series 12AX7-AT / ECC83 Vacuum Tube Preamp Tubes Amplifier Matched Pair (2 PACK) --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/663947132-horizon-series-cv181-at-6sn7-vacuum-tube-amplifier-matched-pair](https://www.desertcart.vn/products/663947132-horizon-series-cv181-at-6sn7-vacuum-tube-amplifier-matched-pair) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
