Chebby - what made the biggest difference to your setup adding the Supplier or a new opamp?
The opamp swap resulted in a cleaner sound with more detail and smoother treble.
The Supplier gave the sound more heft especially during denser/busier moments. Tighter bass too.
Do both upgrades at once. If you can afford the Supplier, then you can afford an extra tenner for the OPA2107AP.
It should be the 8 pin DIP version so you can just ease the old one out and slot the new one in easily without any soldering necessary. Earth yourself before switching them over.

chebby - where did you get the opamp from - i 'be been looking online and found an american company but they a lot more than a tenner - think the superchip was like $35
chebby just found your post on swapping them - missed that first - cheers
I 'chickened out' of getting the opamp cheap from ebay and opted to pay full-whack (£14) from RS Online to ensure I had a genuine and brand new one.
Type in OPA2107AP on ebay uk and you will find plenty being sold for much less.
I have just noticed (from your signature) that you are currently using a Wadia and an MF DAC.
Why the Firestone?
<P>its on by bedside cabinet with my onkyo nds1 and firestone fubar IV - bought because of the dac and headphone amp in one little box</P>
http://www.firestone-audio.eu/shop/products/allproductslisted/fubar4.php - picked it up cheaply
<P>Quite impressed - thinking of getting another to plug my squeezbox into to go in to the spare cyrus amp I have in my computer room or just straight from the computer and will sell the squeezebox although quite like the display!</P>
Did a bit of opamp googiling today and found these two sites that review a few different opamp's. Clicky and clicky
