I have both. A 301 restored in the usual immaculate fashion by @Agrail and a TD-124 mk I which was fully restored and upgraded by Schopper (and Swissonor parts) so neither can be regarded as ‘stock’ items, but particularly the 124 as it has many new parts (sub platter, upper platter, bearing, idler wheel, motor suspension etc. etc)
The 124 has a more delicate sound, but you still know you’re listening to an Idler. The Garrard has more drive and is a more dynamic listen.
Both are lovely decks and I would find it hard to choose which one I like the most. Neither are perfect by any stretch of the imagination, but they are what they are, 60 year old decks (and they’ll probably last another 60) that can give as much enjoyment as anything out there given the right choice of arms, carts and, of course, music.
