help on changing capacitors

Vcap Odams are a better choice for both sound quality and fit.  I directly compared to Miflex in both dac and preamp builds/upgrades and the Odam is clearly the better sounding cap. The Miflex sounds forward and a tad forced in the upper mids and highs compared to the Odams.  The Odams just deliver better better top to bottom coherence while also sounding more real and natural.  They are much smaller and will fit far easier making the job more enjoyable and neat. 

The Odams are mid priced high end caps and nowhere near $1200 a set. They sound 2x better than $50 caps. Just giving the facts and the OP can decide. The Miflex caps I compared were $70 plus each.  The Odams are around $90.  The cheaper Miflex  caps are simply not in the same league as the Odams. 
Cutf Vcaps are very good, but the Odams are very special and many feel no need to spend the Cutf price after using them.  I am one such person. 

An important consideration with that site is the listening tests were only done in speaker crossovers, not electronics. Typically just on the high pass circuit only. This is very important to remember. They will not necessarily sound the same in a preamp, amp or dac circuit.
