Sold Matched pair of New & Unused Burson Audio Discreet Dual OpAmp Modules (generation 1)Two years ago, I purchased one 'matched pair' (that is the way Burson sells them) each of
Burson Audio's single and dual discreet opamps. With the recent sale of my Paradisea+ DAC,
I no longer have use for the dual modules.
I am keeping the single opamp modules for use in the Promitheus DAC. The Promitheus DAC
is currently outfitted with two audio-gd 'moon' single discreet opamps. The Burson Audio
single modules will be swapped in for comparison after I get around to soldering the bypass
capacitors onto them. I can only speak to the change in the Promitheus DAC's sound from
the two standard NE5534 Philips opamps to the audio-gd discreet opamps ...before I could
clearly hear the notes ...now I can hear the 'pluck' of the strings! It is the best inexpensive
tweak I've done yet. I certainly expect no less from the Burson modules.
These dual modules are listed as direct replacements for the following OpAmps:
AD712, AD827, BA5218, C4570, EL2244, JRC4580, JRC5532, JRC5532D, JRC5534, LF353,
LF358, LM4562A, LM833N, LT1057, NE5532, NEC4520, NEC4570, NJM2068D, NJM2114,
NJM2214D, NJM4558, NJM4558D, NJM4560, NJM5532, NJM4558P, OP275, OPA2132,
OPA2134, OPA2604, RC4558D, RC4558, RC4558P, TL052, TL072...
Also included are two pairs each of new and unused capacitors for your choice in using to
bypassing the OpAmp's +/- pins with respect to the OpAmp's grounding wire:
- Vishay MKT1817 0.1 uf, 100v, polyester, radial leaded capacitors
- Vishay MKP1837 0.1 uf, 160v, polypropylene, radial leaded capacitors
[Please do not connect the OpAmp's ground wire to the AC power socket ground
....as I understand this will cause bad things to happen?]If you wish to purchase, please PM me.
$95 USD for the pair. Includes free ConUS shipping via USPS Priority Mail with Signature Confirmation[/b]
Acceptable methods of payment are PayPal (+transaction fees) or USPS money order.
The USPS Tracking Number will be PM'ed to the buyer upon shipping.
The modules will be double-boxed, ridicously well padded and tightly sealed with packaging tape for shipping.
Although my electronics knowledge is limited, I will answer questions related to the modules themselves as
best I can here in this thread.
...thanks for reading
