I was amazed by the quality and sound of this unit, really bringing my vinyl to life and sounding excellent with no ground hum or anything. Even with the stock chinese tubes it sounds great but I will eventually buy a matched pair of other tubes to try out with it for a different sound.
Highly recommended for any vinyl enthusiast that wants their music to come to life and sound nice and organic.
Don’t let the price fool you this product means business!

I understand this may be further enhanced by fiddling around with different valve sets as well. In this latter regard, I did at the same time purchase the ( allegedly) upgraded valves for an extra £15, but I was disappointed when I received these, as despite what it says on the Amazon website, these were not USA manufactured, made in China writ large on the box(!), so I returned these with a frustrated sense of misrepresentation, unusual for Amazon on the whole.
In terms of downsides, I do think that the increased fullness and warmth have come in terms of sacrificing some detail/ clarity at the top end, although as mentioned above the overall sound is still pleasing. I think it's probably very much a matter of personal taste; if you are used to digital music you will notice, more of a rounding off of the overall sound, but in some scenarios this could be handy to reign in excessively harsh treble. Horses for courses really.
On the whole I'm pleased with my purchase and expect I will be keeping this item.
UPDATE: I acquired another set of valves, Siemens NOS, from eBay, and these immediately lifted the sound further, the bottom end retained its clunk but sharpened up, and a lot more top end detail was revealed. So it does seem that whilst the base package is overall good value an extra £15-20 on better valves is money well spent, with European or American valves seeming to he the way to go.
