The preamp is fantastic, but unfortunately the power supply it came with arrived damaged, and i was unable to get a replacement from the seller due to a warehouse issue. I did manage to obtain a replacement power supply and the seller did discount me for the damaged power supply but.

In my 60 years plus of turntables and phono cartridges and preamp experience.. I have rarely come across such an item at such a low cost to both novices and experienced audiophiles alike. Having said that.. the rolls VP 29 phone on stage is one of those rare gems that definitely twinkle went in the ear of the beholder.It's bright red compact appearance easily distinguishes this little Wonder from others. The connections to the rear of the Red Box are well marked on top indicating both left and right inputs and outputs which just happened to be gold-plated and just happen to make me very very happy that they are so! Use good cables and your turntable will sound even better. Incidentally while speaking of the rear connections there is a ground binding post which is absolutely exemplary! It features a small hole in the HD screw connector which accepts both bare wire and lug very nicely and securely. Kudos to this USA company for designing an engineering such a compact Little Wonder.All of this is well and good but how does it sound? Well I'm happy to report that the sound is absolutely exceptional especially at its price point. I seriously doubt that you could do significantly better at twice the price. The sound quality coming from your turntable will be rich detailed and startling as you will discover new nuances in your favorite records. The dimensionality of the image is a wonderful despite what a few nose up in the air audio files might tell you. Anyone who tells you that it lacks such a quality either doesn't know what they're talking about or have turned a blind eye to such a budget product. The fact of the matter is that this budget preamp Wonder brings an extraordinary amount of detail to the table. You need it especially if you're modern receiver or amplifier Lacks a phono stage input. It is designed strictly for moving magnet cartridges not moving coil ones which have an even lower output so please keep that in mind. As such this turns out to be a strength rather than a weakness for the product as the engineering and circuitry and overall build quality is focused on moving magnet performance. The OUTPUT of the VP29 is significantly HIGHER than the cheapies. Please keep this in mind.In conclusion I would say.. especially if you're a beginner in the hobby.. trying to avoid the temptation to choose a made in China $10 preamp but also avoid the more expensive types made anywhere! Trust me when I tell you this is your preamp and I have been looking at this for over the past 10 years and finally pulled the trigger I'm glad I did! Made in USA and it's now hooked up to my maiden USA u-turn orbit basic green turntable and I'm loving it! Your ears will thank you. Happy listening and God bless you and enjoy the music!.. p Js 2

今年、2022年1月に2台目を購入しようとAmazon.com(USA)にアクセスしたものの、メーカー欠品してたためeBayとAmazon.jpを探してたらAmazon.comより少し高価であったがAmazon.jpに在庫があり購入したものです。Rolls VP-29は５万円超以上のフォノアンプに見劣りしない製品だと思います。但し、添付のAC-DCアダプターはチープなため、昔買い込んでいたYAMAHA製pa-6電源アダプターのプラグに極性反転プラグ（センターマイナスに変えて）をかまして使っています。

電源はセンターマイナス（ー）、要注意！ ゲインは仕様上も聴感上も適正。ハム等のノイズは特に気にならない。音質はやや粗く、雑味を感じるが許容範囲。アメリカで評価が高いのも頷ける。手軽に使えて結構です。

Es una gran prefono para el costo, de lo mejor de su gama, buenas dinámicas, frecuencias medias claras sin mermar demasiado los bajos y altos, pequeño y estéticamente bello en ese rojo.
